Seminar Fabrizio Leisen @ Unimib
by Federico Camerlenghi 03 Feb '20

03 Feb '20

Dear all, we are glad to announce the next DEMS seminar: Wednesday, 12th February 2020 Time 12.00, Aula de Lillo, Department of Economics, Management and Statistics (DEMS) Building U7, II floor, University of Milano - Bicocca The speaker is Fabrizio Leisen from University of Kent. *Title:* *On a Class of Objective Priors from Scoring Rules* *Abstract:* Objective prior distributions represent an important tool that allows one to have the advantages of using a Bayesian framework even when information about the parameters of a model is not available. The usual objective approaches work off the chosen statistical model and in the majority of cases the resulting prior is improper, which can pose limitations to a practical implementation, even when the complexity of the model is moderate. In this talk we propose to take a novel look at the construction of objective prior distributions, where the connection with a chosen sampling distribution model is removed. We explore the notion of defining objective prior distributions which allow one to have some degree of flexibility, in particular in exhibiting some desirable features, such as being proper, or log-concave, convex etc. The basic tool we use are proper scoring rules and the main result is a class of objective prior distributions that can be employed in scenarios where the usual model based priors fail, such as mixture models and model selection via Bayes factors. In addition, we show that the proposed class of priors is the result of minimising the information it contains, providing solid interpretation to the method. This is a work in collaboration with C. Villa and S. G. Walker. Best wishes, Federico Camerlenghi -- Federico Camerlenghi Department of Economics, Management and Statistics University of Milano Bicocca, Milano, Italy. web-page: https://www.unimib.it/federico-camerlenghi

Polimi Finance Seminars Paolo Di Tella (TU-Dresden)
by Carlo Sgarra 27 Jan '20

27 Jan '20

On Tuesday, February 11, at 10:30 in the Seminar Room at the third floor of the Department of Mathematics (Politecnico di Milano), in the framework of the quantitative finance seminars, Paolo Di Tella (TU-Dresden) will give a talk with title: * Semistatic and sparse variance-optimal hedging. ABSTRACT We consider the problem of hedging a contingent claim with a “semistatic” strategy composed of a dynamic position in one asset and static (buy‐and‐hold) positions in other assets. We give general representations of the optimal strategy and the hedging error under the criterion of variance optimality and provide tractable formulas using Fourier integration in case of the Heston model. We also consider the problem of optimally selecting a sparse semistatic hedging strategy, i.e., a strategy that only uses a small subset of available hedging assets and discuss parallels to the variable‐selection problem in linear regression. The methods developed are illustrated in an extended numerical example where we compute a sparse semistatic hedge for a variance swap using European options as static hedging assets. (joint work with M. Haubold, M. Keller-Ressel). All people interested are kindly invited to attend the talk. Carlo Sgarra

Probability Seminar: Alessandra Cipriani (TU Delft) [Padova 31/01, 11.30]
by alessandra bianchi 21 Jan '20

21 Jan '20

Dear Colleagues, we would like to invite you to the following Probability seminar that will take place at the Department of Mathematics of Padova, on January 31. ________________________________________________________ Speaker: Alessandra Cipriani (TU Delft) Title: Dynamical fitness models: evidence of universality classes for preferential attachment 31 JANUARY (Friday), 11:30; ROOM 1BC45, Dipartimento di Matematica “Tullio Levi-Civita”, Via Trieste 63, Padova Abstract: In this talk we study different variations of a particular class of random graphs called preferential attachment models with fitness. These are dynamic graphs in which, at every time step, a new node attaches itself to an older one with probability proportional to the degree and a random factor associated to the node, called the fitness. Motivated by learning mechanisms of real-life networks, we assume the fitness to be a Moving Average process MA(q) with positive increments. We study different properties of such models, for example the degree distribution, the attachment probability and the phenomenon of Bose-Einstein condensation. Finally we provide evidence that, tuning the parameters of the fitness process, we fall into two universality classes represented by the well-known Albert-Barabàsi model and Bianconi-Barabàsi model. This implies the robustness of heavy tails in the degree distribution under random perturbations of the attachment rule. All of you are very welcome.

Si comunica che il 30 gennaio 2020 alle ore 14.00 presso l'Aula Riunioni dell'Istituto per le Applicazioni del Calcolo (sede di Roma) si terrà il seguente seminario: Relatore: Professor Alberto Lanconelli (Universita' di Bologna) Titolo: Absolute continuity and Fokker-Planck equation for the law of Wong-Zakai approximations of Ito SDEs Abstract: We investigate the regularity of the law of Wong-Zakai-type approximations for Ito stochastic differential equations. These approximations solve random differential equations where the diffusion coefficient is Wick-multiplied by the smoothed white noise. Using a criterion based on the Malliavin calculus we establish absolute continuity and a Fokker-Planck-type equation solved in the distributional sense by the density. The parabolic smoothing effect typical of the solutions of Ito equations is lacking in this approximated framework; therefore, in order to prove absolute continuity, the initial condition of the random differential equation needs to possess a density itself. -- *Giovanni Luca Torrisi Consiglio Nazionale delle Ricerche, Rome, Italy Homepage: http://www.iac.rm.cnr.it/~torrisi/* * *

Seminario di Francesco Caravenna a Roma 1
by Faggionato, Alessandra 21 Jan '20

21 Jan '20

Buongiorno Lunedì 27.01 alle 16:00 Francesco Caravenna (Università di Milano-Bicocca) terrà il seguente seminario in Sala di Consiglio del Dipartimento di Matematica La Sapienza. Title: On the two-dimensional KPZ and Stochastic Heat Equation Abstract: We consider the Kardar-Parisi-Zhang equation (KPZ) and the multiplicative Stochastic Heat Equation (SHE) in two space dimensions, driven by with space-time white noise. These singular PDEs are "critical" and lack a solution theory, so it is standard to consider regularized versions of these equations - e.g. convolving the noise with a smooth mollifier - and to investigate the behavior of the regularized solutions when the regularization is removed. Based on joint works with Rongfeng Sun and Nikos Zygouras, we show that these regularized solutions undergo a phase transition as the noise strength is varied on a logarithmic scale, with an explicit critical point. In the sub-critical regime, the regularized solutions of both KPZ and SHE exhibit so-called Edwards-Wilkinson fluctuations, i.e. they converge to the solution of the *additive* Stochastic Heat Equation (after centering and rescaling), with a non-trivial constant on the noise. We finally discuss the critical regime, where many questions are open.

Complexity72h Call for Tutors
by Mateusz Wilinski 19 Jan '20

19 Jan '20

Dear colleagues, We are glad to announce the *third edition of the Complexity72h workshop*, which will take place at LUISS, Rome, Italy, on *July 1-4 2020*, as pre-event of the *NetSci 2020* Conference. Complexity72h is an interdisciplinary workshop whose aim is to bring together young researchers from different fields of complex systems and complex networks. Participants form teams and carry out projects in a three days' time, i.e. 72 hours. The goal of each team is to upload on the arXiv a report of their work by the end of the event. The previous two editions have been a success: 11 out of 11 projects have become arXiv preprints and new collaborations have been born. Each team will have a tutor that: 1. designs and proposes the project; 2. supervises its execution; 3. provides the necessary knowledge and data. *Do you want to become a Complexity72h tutor?* We are opening a *call for tutors* targeting researchers in complex systems and networks. We are looking for people who wish to propose a stimulating project to a team of highly motivated students and postdocs, and have the stamina to carry it out in 72 hours. But is it really possible to do it in just 72 hours? To succeed, we need: 1. A motivated and multidisciplinary team of resilient researchers; 2. A comfortable research environment and supportive staff; 3. A solid and feasible research project and a tutor who can make it happen. We provide the first two. It is up to you to provide the last point. *Send your project proposal (title and abstract) and short CV to: complexity72h [at] gmail [dot] com* , or get in touch with us as soon as possible if you have any questions. *The call for tutors deadline is February 7th, 2020.* Looking forward to your ideas.

-- AVVISO DI SEMINARI DI PROBABILITÀ E STATISTICA MATEMATICA Title: The risk model with stochastic premiums and a multi-layer dividend strategy by Olena Ragulina Faculty of Mechanics and Mathematics, Taras Shevchenko National University of Kyiv Abstract: The lecture is devoted to a generalization of the risk model with stochastic premiums where dividends are paid according to a multi-layer dividend strategy. First of all, we derive piecewise integro-differential equations for the Gerber-Shiu function and the expected discounted dividend payments until ruin. Next, we concentrate on the detailed investigation of the model in the case of exponentially distributed claim and premium sizes and find explicit formulas for the ruin probability as well as for the expected discounted dividend payments. Moreover, we obtain an exponential bound for the ruin probability under certain conditions and study these conditions for some special distributions of claim and premium sizes. Lastly, numerical illustrations for some multi-layer dividend strategies are presented. -- Title: The first-passage time properties of the Jacobi process and applications to neuronal modeling by Giuseppe D'Onofrio Dipartimento di Matematica "Giuseppe Peano", Università di Torino Abstract: Nonlinear dynamical systems are often affected by different sources of noise and the usual belief is that the presence of noise can hinder or deteriorate the signal transmission in the system. However it has been observed, both in theoretical models and experiments, that random fluctuations can sometimes improve information processing. Mathematical models in neuroscience are one of the most prominent examples of phenomena for which the noise is of primary importance or even a part of the signal itself rather than a source of inefficiency and unpredictability. Our aim is to contribute to the discussion on the role of noise, studying the effects of a multiplicative noise on the performance of single neuron models using an analytical approach on the related first-passage-time problem. We consider a model where the evolution of the neuronal membrane depolarization between two consecutive spikes is described by a Jacobi process. We analyze the spiking activity of the neuron under study through the firing rate and the variability of the output related to the first two moments of the random variable first-passage time and we describe the occurrence of a phenomenon of coherence resonance. In particular we present counterintuitive effects due to the presence of the multiplicative noise and its dependence on the input parameters. Based on joint work with Petr Lansky (Czech Academy of Sciences) and Massimiliano Tamborrino (University of Warwick). I seminari si terranno il 23 Gennaio 2020 ore 15:00 e ore 15:45, rispettivamente, in Aula G terzo livello del Dipartimento di Matematica e Applicazioni, Università di Napoli FEDERICO II, Complesso di Monte Sant'Angelo, Via Cintia, Napoli. -- Enrica Pirozzi Dipartimento di Matematica e Applicazioni Universita' di Napoli FEDERICO II Via Cintia, Monte S.Angelo, 80126, NAPOLI, ITALY Tel. 081 675634 https://www.docenti.unina.it/ENRICA.PIROZZI

Dear all, On Wednesday, 22 January 2020 — at 11:30 — at the Scuola Normale Superiore (Room: Aula Fermi) Dr Tiziano De Angelis (University of Leeds) will hold the following Seminar: Title Probabilistic results concerning smoothness of the value function and of the free boundary in optimal stopping Abstract I will present probabilistic proofs of some regularity properties for the value function of general optimal stopping problems and for the associated optimal boundaries. In particular this talk focuses on C^1 regularity of the value function and Lipschitz continuity of the optimal boundary. Most of our arguments rely on fundamental concepts from the theory of Markov processes and bridge the probabilistic and the analytical strands of the literature on free boundary problems. I will also illustrate situations in which our work improves or complements known facts from PDE theory. (based on https://epubs.siam.org/doi/pdf/10.1137/17M1113709 <https://epubs.siam.org/doi/pdf/10.1137/17M1113709> and https://arxiv.org/abs/1812.04564 <https://arxiv.org/abs/1812.04564>) Feel free to forward this announcement to your colleagues.

Seminar Cuturi @Bocconi
by Giacomo Zanella 16 Jan '20

16 Jan '20

We kindly invite you to the following BIDSA seminar: “Differentiable Ranking and Sorting using Optimal Transport” Marco Cuturi (Google Brain / ENSAE) Friday, January 17, 2020 | 12:30 | Room 3-e4-sr03 (third floor) Bocconi University, Via Roentgen 1, Milan Abstract: We propose in this paper proxy operators for ranking and sorting that are differentiable. To do so, we leverage the fact that sorting can be seen as a particular instance of the optimal transport (OT) problem between two univariate uniform probability measures, the first measure being supported on the family of input values of interest, the second supported on a family of increasing target values (e.g. 1,2,...,n if the input array has n elements). Building upon this link, we propose generalized rank and sort operators by considering arbitrary target measures supported on m values, where m can be smaller than n. We recover differentiable algorithms by adding to this generic OT problem an entropic regularization, and approximate its outputs using Sinkhorn iterations. To illustrate the versatility of these operators, we use the soft-rank operator to propose a new classification training loss that is a differentiable proxy of the 0/1 loss. Using the soft-sort operator, we propose a new differentiable loss for trimmed regression. Speaker: Marco Cuturi joined Google Brain, in Paris, in October 2018. He graduated from ENSAE (2001), ENS Cachan (Master MVA, 2002) and holds a PhD in applied maths obtained in 2005 at Ecole des Mines de Paris. He worked as a post-doctoral researcher at the Institute of Statistical Mathematics, Tokyo, between 11/2005 and 3/2007. He worked in the financial industry between 4/2007 and 9/2008. After working at the ORFE department of Princeton University between 02/2009 and 08/2010 as a lecturer, he was at the Graduate School of Informatics of Kyoto University between 9/2010 and 9/2016 as a tenured associate professor from 10/2013. He then joined ENSAE, the french national school for statistics and economics, in 9/2016, where he still teaches. His recent proposal to solve optimal transport using an entropic regularization has re-ignited interest in optimal transport and Wasserstein distances in the machine learning community. His work has recently focused on applying that loss function to problems involving probability distributions, e.g. topic models / dictionary learning for text and images, parametric inference for generative models, regression with a Wasserstein loss and probabilistic embeddings for words.

Ernesto De Vito @ Roma Tor Vergata
by Anna Vidotto 16 Jan '20

16 Jan '20

Dear all, I would like to announce the following talk that will be held on Thursday January 23rd 2020, at 4:30 PM, in Aula D’Antoni of the Department of Mathematics, University of Rome Tor Vergata. Speaker: Ernesto De Vito Title: Multi-Scale Vector Quantization with Reconstruction Trees Abstract: The aim of vector quantization is a parsimonious reconstruction of unsupervised data as provided by K-means and geometric multi-resolution analysis, to name a few. In the talk I will present a multi-scale algorithm for vector quantization and study its statistical properties. The proposed approach is inspired by decision trees and is based a family of given partitions, to quickly explore the data in a coarse to fine-multi-scale-fashion. The main technical contribution is an analysis of the expected distortion achieved by the proposed algorithm. Both asymptotic and finite sample results are derived. The presentation is based on a joint work with E. Cecini and L. Rosasco.

seminario Djehiche a Milano 27/1/2020
by Marco Alessandro Fuhrman 15 Jan '20

15 Jan '20

Il prof. Boualem Djehiche (KTH Stockholm) terrà un seminario dal titolo On a class of mean-field reflected backward stochastic differential equations and the related obstacle problem. Il seminario è fissato alle ore 10:30 del 27/1/2020 presso il Dipartimento di Matematica dell'Università di Milano (via Saldini 50), in aula C (II piano). Tutti gli interessati sono cordialmente invitati. Un sommario è riportato sotto. Il prof. Djehiche è ospite del Dipartimento per tutta la settimana. Cordialmente, Marco Fuhrman --------------------------- Abstract. In this talk I will review some recent results on the solvability of a class of reflected backward stochastic differential equations (BSDEs) (driven by the Brownian motion) of mean-field type, where the mean-field interaction in terms of the distribution of the Y-component of the solution enters both the driver and the lower obstacle. When the reflected BSDE is driven by an underlying Markov diffusion, it is possible to derive a related obstacle problem in the form of a variational inequality involving differential operators w.r.t. both the space and the probability measure components. -------------------------- <signaturebeforequotedtext></signaturebeforequotedtext><signatureafterquotedtext></signatureafterquotedtext>

de Finetti Risk Seminar - January 2020
by Emanuela Rosazza 14 Jan '20

14 Jan '20

On behalf of the Scientific Committee of the de Finetti Risk Seminars, we are glad to invite you to participate at the following Lecture Quadratic Hedging and Optimization of Option Exercise Policies in Incomplete Markets and Discrete Time Nicola Secomandi Tepper School of Business – Carnegie Mellon University Abstract. This paper extends quadratic hedging from European to Bermudan options in discrete time when markets are incomplete and investigates its use for supporting exercise policy optimization. The key idea is to construct date specific approximate replicating portfolios. Hedging any given exercise policy can be done by solving a collection of stochastic dynamic programs. Optimizing the exercise policy based on the resulting martingale measure requires care. If this measure is risk neutral (RN), the value of an optimal such policy, which can be obtained by augmenting the hedging model with an exercise policy optimization step, is a no arbitrage one. Otherwise this approach must be refined by imposing time consistency on exercise policies, although the value of the resulting exercise policy may not be arbitrage free. Following the common pragmatic strategy of specifying quadratic hedging under an RN measure, e.g., one calibrated to market prices, avoids these issues. In particular, it provides a simple hedging policy with immediate practical applicability and is equivalent to exercise policy optimization under RN valuation, thus complementing it with a consistent hedging policy. A simple numerical example shows that this procedure generates effective hedging policies LOCATION: The seminar will be held on Wednesday, January 15, at 18.00 at room 3-E4-SR03, Bocconi University, Via Rontgen 1, 3rd floor, Milano.

Seminar Announcement: M. Glanzer (univie) at Polimi
by Carlo Sgarra 14 Jan '20

14 Jan '20

On Monday, January 21, at 11:00 o'clock, in the Seminar Room located at the third floor of the MATHEMATICS Department ( POLITECNICO di Milano) MARTIN GLANZER of the University of Vienna will give a talk on the following subject: Stochastic Optimization with Multiple Time Scales ( Joint work with G. Pflug) All interested people are kindly invited to participate. ABSTRACT Real-world multistage stochastic optimization problems are often characterized by the fact that the decision maker may take actions only at specific points in time, even if relevant data can be observed much more frequently. In such a case there are not only multiple decision stages present but also several observation periods between consecutive decisions, where profits/costs occur contingent on the stochastic evolution of some uncertainty factors. We present a tailor-made modeling framework for such problems, which allows for a computationally efficient solution. We first establish new results related to the approximation of (Markovian) stochastic processes by scenario lattices. In a second step, we incorporate the multiscale feature by leveraging the theory of stochastic bridge processes. The ingredients to our proposed modeling framework are elaborated explicitly for various popular examples, including both diffusion and jump models. In particular, we present new results related to the simulation of compound Poisson bridges. Finally, we discuss a valuation problem of a thermal power plant, where implementing our multiscale modeling framework turned out to be particularly convenient. If time permits, we incorporate model ambiguity into the power plant valuation problem and show some numerical results.

Probability Seminar: Richard Kraaij (TUDelft) [Padova, Tue 14/01 (TOMORROW), 11am]

*** REMINDER *** ____________________________________________________________________________________________________ DR. RICHARD C. KRAAIJ (Delft University of Technology) “Large deviations for weakly coupled slow-fast systems via the comparison principle of an associated Hamilton-Jacobi equation” Tuesday 14 January (TOMORROW), 11:00; room 1BC50, Dipartimento di Matematica “Tullio Levi-Civita”, Via Trieste 63, Padova ABSTRACT. In statistical physics many interesting phenomena, e.g. behavior of systems at critical parameters or in the theory of hydrodynamic limits, arise from systems having multiple time-scales. A slow component is influenced by fast components, and as the number of interacting components tends to infinity, limiting results for the slow component are obtained in terms of `averaged' versions of the fast components. I will consider in my talk the fluctuations (large deviations) of coupled Markovian systems with two-time scales. These fluctuations can arise from two sources: fluctuations of the slow process itself, or fluctuations of the large time averages of the fast process, effectively leading to a competition of two fluctuation effects. To obtain the large deviation principle, we consider an associated Hamilton-Jacobi-Bellman equation of which the Hamiltonian is given in terms of the two fluctuation effects. We establish under mild conditions that this Hamilton-Jacobi-Bellman equation is well-posed, and as a consequence that we have a large deviation principle for a wide class of weakly coupled Markov processes.

Maria Gordina @ Roma Tor Vergata

Dear all, I would like to announce the following talk that will be held on *Thursday January* *16th* 2020, at *4:30 PM*, in *Aula Dal Passo* of the Department of Mathematics, University of Rome Tor Vergata. Speaker: *Maria Gordina* (University of Connecticut) Title: *Stochastic analysis and geometric functional inequalities* Abstract: We will survey different methods of proving functional inequalities for hypoelliptic diffusions and the corresponding heat kernels. Some of these methods rely on geometric methods such as curvature-dimension inequalities (due to Baudoin-Garofalo), and some are probabilistic such as coupling, and finally some use structure theory and a Fourier transform on Lie groups. For nilpotent groups, the latter can be interpreted as an eigenfunction expansion of the hypoelliptic heat kernel. This is based on joint work with F. Baudoin, B. Driver, T. Melcher, Ph. Mariano. This seminar is part of the activity of the MIUR Department of Excellence Grant 2018-2022, CUP E83C18000100006.

SEMINARIO DI PROBABILITA’ E STATISTICA MATEMATICA IL giorno 14/01/2020, alle ore 14 nell’Aula di Consiglio del Dipartimento di Matematica, Sapienza Università di Roma Il prof. Antonio Galves dell’Universidade de Sao Paulo terrà una conferenza dal titolo ESTIMATING THE INTERACTION GRAPH OF STOCHASTIC NEURAL DYNAMICS Abstract: We address the question of statistical model selection for a class of stochastic models of biological neural nets.Models in this class are systems of interacting chains with memory of variable length. Each chain describes the activity of a single neuron, indicating whether it spikes or not at a given time. The spiking probability of a given neuron depends on the time evolution of its presynaptic neurons since its last spike time. When a neuron spikes, its potential is reset to a resting level and postsynaptic current pulses are generated, modifying the membrane potential of all its postsynaptic neurons. The relationship between a neuron and its pre- and postsynaptic neurons defines an oriented graph, the interaction graph of the model. The goal is to estimate this graph based on the observation of the spike activity of a finite set of neurons over a finite time. We provide explicit exponential upper bounds for the probabilities of under- and overestimating the interaction graph restricted to the observed set and obtain the strong consistency of the estimator. Our result does not require stationarity nor uniqueness of the invariant measure of the process. Joint work with A. Duarte, E. Locherbach and G. Ost.

Probability Seminar: Richard Kraaij (TUDelft) [Padova, Tue 14/01, 11am]
by Francesca Collet 07 Jan '20

07 Jan '20

*** Apologies for cross-posting *** Dear Colleagues, we would like to invite you to the following Probability seminar that will take place at the Department of Mathematics, University of Padova, on January 14. ____________________________________________________________________________________________________ DR. RICHARD C. KRAAIJ (Delft University of Technology) “Large deviations for weakly coupled slow-fast systems via the comparison principle of an associated Hamilton-Jacobi equation” 14 JANUARY (Tuesday), 11:00; ROOM 1BC50, Dipartimento di Matematica “Tullio Levi-Civita”, Via Trieste 63, Padova ABSTRACT. In statistical physics many interesting phenomena, e.g. behavior of systems at critical parameters or in the theory of hydrodynamic limits, arise from systems having multiple time-scales. A slow component is influenced by fast components, and as the number of interacting components tends to infinity, limiting results for the slow component are obtained in terms of `averaged' versions of the fast components. I will consider in my talk the fluctuations (large deviations) of coupled Markovian systems with two-time scales. These fluctuations can arise from two sources: fluctuations of the slow process itself, or fluctuations of the large time averages of the fast process, effectively leading to a competition of two fluctuation effects. To obtain the large deviation principle, we consider an associated Hamilton-Jacobi-Bellman equation of which the Hamiltonian is given in terms of the two fluctuation effects. We establish under mild conditions that this Hamilton-Jacobi-Bellman equation is well-posed, and as a consequence that we have a large deviation principle for a wide class of weakly coupled Markov processes. Based on joint work with Mikola Schlottke (Eindhoven, The Netherlands). ____________________________________________________________________________________________________ All of you are very welcome.

Seminari congiunti ASI - Dipartimento Matematica Tor Vergata

07 Jan '20

Annuncio Seminari congiunti ASI - Dipartimento Matematica Tor Vergata *9 Gennaio 2020* Aula Dal Passo, Edificio Sogene *Ore 14: Gianluca Polenta, ASI Space Science Data Centre* Title: Cosmology through CMB maps Abstract: The Cosmic Microwave Background is a fundamental source of information for cosmology. In the standard inflationary scenario, the CMB can be described to first order as a Gaussian random field on the sphere, and as such cosmological information is encoded in the two-point correlation function or in the angular power spectrum. To derive these quantities as well as the likelihood function needed to estimate the cosmological parameters, a number of estimators have been developed following different trade-off between optimality, unbiasedness, and computational resources, also depending on the characteristics of the dataset to be analysed. In this talk I will review the different classes of estimators used in the CMB data analysis, focusing in particular to the solutions adopted for the ESA Planck satellite, which produced CMB full sky maps of unprecedented quality. Finally, I will briefly discuss how CMB non-Gaussianity, isotropy, and those anomalies found in the analysis of Planck data can be used to further test the inflationary paradigm. *Ore 15: Domenico Marinucci, Department of Mathematics, University ofRome Tor Vergata* Title: Critical Points, Multiple Testing and Point Source Detection for Cosmological Data Abstract: In this talk, we shall review some mathematical issues arising in the analysis of Cosmic Microwave Background (CMB) radiation data; many of these issues can be related to the investigation of functionals of independent interest in random geometry. We will first review some results on harmonic analysis for spherical random fields, on the construction of spherical wavelets and on their stochastic properties; we will then show how to compute the asymptotic distribution of critical points for Fourier/wavelet components of random fields, and we will establish some ergodicity results, in the high-frequency limit. We will then investigate how to exploit these results to implement multiple testing procedures for detection of point sources (Galaxies) in CMB Data; the resulting tests will be shown to exhibit a number of optimality properties. Applications to CMB data from the Planck collaboration will also be briefly illustrated. --------- Anna Vidotto PostDoc Researcher Dipartimento di Matematica Università degli Studi di Roma Tor Vergata https://sites.google.com/view/annavidotto

Seminario Lionel Levine (Cornell), Università La Sapienza, Martedì 7 Gennaio

REMINDER Seminario di Probabilità Speaker: Lionel Levine (Cornell University) Title: Random walks with local memory Martedì 7 Gennaio, ore 14:00 (sharp) Aula di Consiglio Dipartimento di Matematica Università di Roma La Sapienza Piazzale Aldo Moro, 5 Abstract: The theme of this talk is walks in a random environment of "signposts" altered by the walker. I'll focus on three related examples: 1. Rotor walk on Z^2. Your initial signposts are independent with the uniform distribution on {North,East,South,West}. At each step you rotate the signpost at your current location clockwise 90 degrees and then follow it to a nearest neighbor. Priezzhev et al. conjectured that in n such steps you will visit order n^{2/3} distinct sites. I'll outline an elementary proof of a lower bound of this order. The upper bound, which is still open, is related to a famous question about the path of a light ray in a grid of randomly oriented mirrors. This part is joint work with Laura Florescu and Yuval Peres. 2. p-rotor walk on Z. In this walk you flip the signpost at your current location with probability 1-p and then follow it. I'll explain why your scaling limit will be a Brownian motion perturbed at its extrema. This part is joint work with Wilfried Huss and Ecaterina Sava-Huss. 3. p-rotor walk on Z^2. Rotate the signpost at your current location clockwise with probability p and counterclockwise with probability 1-p, and then follow it. This walk “organizes” its environment by destroying cycles of signposts. A native environment -- stationary in time, from your perspective as the walker -- is an orientation of the uniform spanning forest, plus one additional edge. This part is joint work with Swee Hong Chan, Lila Greco, and Peter Li: https://arxiv.org/abs/1809.04710 ******************************** Vittoria Silvestri Assistant Professor Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome ********************************

Seminario Lionel Levine (Cornell), Università La Sapienza
by Silvestri, Vittoria 16 Dec '19

16 Dec '19

PREANNUNCIO DI SEMINARIO (seguirà un reminder) Seminario di Probabilità Speaker: Lionel Levine (Cornell University) Title: Random walks with local memory Martedì 7 Gennaio, ore 14:00 (sharp) Aula di Consiglio Dipartimento di Matematica Università di Roma La Sapienza Piazzale Aldo Moro, 5 Abstract: The theme of this talk is walks in a random environment of "signposts" altered by the walker. I'll focus on three related examples: 1. Rotor walk on Z^2. Your initial signposts are independent with the uniform distribution on {North,East,South,West}. At each step you rotate the signpost at your current location clockwise 90 degrees and then follow it to a nearest neighbor. Priezzhev et al. conjectured that in n such steps you will visit order n^{2/3} distinct sites. I'll outline an elementary proof of a lower bound of this order. The upper bound, which is still open, is related to a famous question about the path of a light ray in a grid of randomly oriented mirrors. This part is joint work with Laura Florescu and Yuval Peres. 2. p-rotor walk on Z. In this walk you flip the signpost at your current location with probability 1-p and then follow it. I'll explain why your scaling limit will be a Brownian motion perturbed at its extrema. This part is joint work with Wilfried Huss and Ecaterina Sava-Huss. 3. p-rotor walk on Z^2. Rotate the signpost at your current location clockwise with probability p and counterclockwise with probability 1-p, and then follow it. This walk “organizes” its environment by destroying cycles of signposts. A native environment -- stationary in time, from your perspective as the walker -- is an orientation of the uniform spanning forest, plus one additional edge. This part is joint work with Swee Hong Chan, Lila Greco, and Peter Li: https://arxiv.org/abs/1809.04710 ******************************** Vittoria Silvestri Assistant Professor Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome ********************************

Seminar at Scuola Normale Superiore, 17 December 2019, Luciano Campi
by Giulia Livieri 13 Dec '19

13 Dec '19

Dear all, On Tuesday, 17 December 2019 — at 11:30 — at the Scuola Normale Superiore (Room: Aula Bianchi Scienze) Prof. Luciano Campi (London School of Economics) will hold the following Seminar: Title : Correlated Equilibria and Mean Field Game Abstract: Mean field games are limit models for symmetric N-player games, as N tends to infinity, where the pre-limit models are solved in terms of Nash equilibria. A generalization of the notion of Nash equilibrium, due to Robert Aumann (1973, 1987), is that of a correlated equilibrium. Here, we discuss, in a simple non-static setting, the mean field game limit for correlated equilibria. We give a definition of correlated mean field game solution, prove that it arises as limit of N-player correlated equilibria in restricted (”open-loop”) Markov feedback strategies, and show how to construct approximate N-player equilibria starting from a correlated mean field game solution. We also compare our definition to the one by Lacker (2018) of weak solutions for mean field games without a common noise. (Joint work with Markus Fischer, Padova University) Fill free to forward this announcement to your colleagues.

Doppio Seminario PELUCHETTI & KOWAL
by Pierpaolo De Blasi 13 Dec '19

13 Dec '19

Mercoledi 18 Dicembre 2019, presso il nuovo edificio del Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terranno i seguenti due seminari: ———————————————————————— ore 11.00 Stefano PELUCHETTI (Cogent Labs Tokyo) DEEP NEURAL NETWORKS AND STOCHASTIC PROCESSES We review deep neural networks and their training, and then focus on the connection between neural networks and stochastic processes. Deep neural networks at initialization correspond to prior models in function space, and under appropriate assumptions they converge to Gaussian processes in the limit of infinite width. While this connection holds "a priori", it is possible to derive similar results for "a posteriori" training via gradient descent. In this talk we discuss these and related results, and we introduce a recent line of research which generalizes established results to non-Gaussian initializations and stochastic processes arising in the limit of infinite depth. ———————————————————————— ore 12.00 Daniel KOWAL (Rice University) SCALABLE BAYESIAN INFERENCE AND SUMMARIZATION FOR FUNCYIONAL DATA Modern scientific monitoring systems, such as wearable and implantable devices, commonly record data over a continuous domain at high resolutions. These functional data are high-dimensional, strongly correlated, and usually measured concurrently with other variables of interest. Bayesians models for functional data are particularly appealing: they accommodate multiple dependence structures, handle missing or irregularly-spaced data, and provide regularization via shrinkage priors. However, these models are often complex, computationally intensive, and difficult to interpret. This talk will focus on two fundamental challenges for Bayesian functional data analysis: (1) constructing sufficiently flexible and scalable functional regression models and (2) extracting interpretable posterior summaries. The proposed modeling framework is nonparametric and uses an unknown functional basis to learn prominent functional features, which are associated with scalar predictors within a regression model. A customized projection-based Gibbs sampler provides posterior inference with linear time complexity in the number of predictors, which is empirically faster than existing frequentist and Bayesian alternatives. Using the posterior distribution, a decision theoretic approach for Bayesian variable selection is developed, which identifies a subset of covariates that retains nearly the predictive accuracy of the full model. The methodology is applied to actigraphy data to investigate the association between intraday physical activity and responses to a sleep questionnaire. ———————————————————————— Tutti gli interessati sono invitati a partecipare. Il seminario è organizzato dalla "de Castro" Statistics Initiative (www.carloalberto.org/stats <http://www.carloalberto.org/stats>) in collaborazione con il Collegio Carlo Alberto. Cordiali saluti, Pierpaolo De Blasi --- University of Torino & Collegio Carlo Alberto https://sites.google.com/a/carloalberto.org/pdeblasi/ <https://sites.google.com/a/carloalberto.org/pdeblasi/>

Seminari di H.A.Mimun e G. Panizo a Roma, Univ. La Sapienza
by Faggionato, Alessandra 11 Dec '19

11 Dec '19

Buongiorno sotto trovate l'annuncio per due seminari che si terranno al Dipartimento di Matematica dell'Università La Sapienza a Roma la prossima settimana. grazie saluti alessandra ****************************************************************************************** *When*: Monday 16 December, 16:00 *Where*: Room B, Department of Mathematics, Sapienza University, Rome. *Speaker*: H.A. Mimun (Department of Mathematics, Sapienza University, Rome) *Title:* Percolation in the Miller-Abrahams random resistor network *Abstract: *The Miller-Abrahams random resistor network is used to study electron transport in amorphous solids. This resistor network is given by the complete random graph built on a marked homogeneous Poisson point process on R^d and each edge {x,y} is associated to a filament with conductance depending on the temperature, the distance between the points x,y and their associated marks. In this talk we consider the subgraph containing only edges with lower bounded conductances and, using the method of randomized algorithms developed by Duminil-Copin et al. and the renormalization argument proposed by Grimmett and Marstrand, we analyze the connection probabilities and the left-right crossings in appropriate regimes. These percolation properties are key ingredients for understanding the asymptotic behavior at low temperature of the effective conductivity of the Miller-Abrahams random resistor network. Joint work with Alessandra Faggionato (Sapienza University, Rome). ****************************************************************************************** *When*: Tuesday 17 December, 14:00 (sharp!) *Where:* Sala di Consiglio, Department of Mathematics, Sapienza University, Rome. *Speaker: *Gonzalo Panizo Garcia, IMCA, Lima, Perù *Title:* A self-interacting random walk *Abstract:* In 2011, Benjamini, Kozma and Schapira introduced a “balanced excited random walk” in the 4-dimensional lattice. In 2016, a similar model was studied by Peres, Schapira and Sousi in the 3-dimensional lattice. Here we generalize their constructions in the d-dimensional lattice, in the following way: if the walk visits a site for the first time, it makes a simple random walk step in the first d_1 dimensions, whereas if the site has been already visited, it makes a simple random walk step in the last d_2 coordinates. Both BKS and PSS proved transience in the non-overlapping case d=d_1+d_2, with d_1=d_2=4 (BKS) and d_1=1, d_2=3 (PSS). In this talk some result for the overlapping case (d_1+d_2>d) will be presented, in particular for d=4, d_1=2 and d_2=3. (Joint work with D. Camarena and A. Ramirez). -- ************************************************* Prof. Alessandra Faggionato http://www1.mat.uniroma1.it/~faggionato/ Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome Office 5, Phone (0039) 06 49913252 *************************************************

Seminario Antonio Lerario Roma Tor Vergata
by Anna Vidotto 06 Dec '19

06 Dec '19

I would like to announce the following talk that will be held on Thursday December 12th 2019, at 4:30 PM, in Aula Dal Passo of the Department of Mathematics, University of Rome Tor Vergata. Speaker: Antonio Lerario (SISSA Trieste) Title: Low-degree approximation of real singularities Abstract: In this talk I will discuss some recent results that allow to approximate a real singularity given by polynomial equations of degree $d$ (e.g. the zero set of a polynomial, or the number of its critical points of a given Morse index) with a singularity which is diffeomorphic to the original one, but it is given by polynomials of degree $O(d^{1/2}log d)$. The approximation procedure is constructive (in the sense that one can read the approximating polynomial from a linear projection of the given one) and quantitative (in the sense that the approximating procedure will hold for a subset of the space of polynomials with measure increasing very quickly to full measure as the degree goes to infinity). This is based on a combination of joint works with P. Breiding, D. N. Diatta and H. Keneshlou. — This talk is part of the activity of the MIUR Excellence Department Project CUP E83C18000100006 — —————— Anna Vidotto PostDoc Researcher Dipartimento di Matematica Università degli Studi di Roma Tor Vergata https://sites.google.com/view/annavidotto

Please note that the conference room allows only for a very limited number of participants. COURSE OUTLINE The aim of this course is to introduce the fundamental concepts and state-of-art methods for causal inference under the potential outcome framework. The lectures will be organized by the treatment assignment mechanisms. Topics will cover randomized experiments, observational studies with ignorable assignment mechanisms, natural experiments, sequential ignorable longitudinal treatments. Recent advances related to machine learning and more complex situations such as spatial-temporal treatments and interference will also be discussed. All methods will be illustrated via real case studies in health studies, economics and biology. Though the causal framework and most of the methods are independent of the inferential paradigm, an emphasis will be put on the Bayesian paradigm for inference. TENTATIVE PROGRAM See the daily program on the website. PRACTICAL INFORMATION The school will replicate the successful format of the previous years, and will feature lectures and practical sessions (run by a junior researcher), as well as participants' talks. It will start on Monday after lunch and end on Friday before lunch; Wednesday afternoon is free. Info on accommodation will appear soon on the website. Florence (Firenze) is easily accessible by train, airplane or car.

Seminario di Tyler Helmuth (Bristol) a Roma Tre, 12-12-2019
by Alexandre Stauffer 03 Dec '19

03 Dec '19

SEMINARIO Probabilita' Tyler Helmuth (University of Bristol) Titolo: Random spanning forests and hyperbolic symmetry Giovedi' 12 Dicembre 2019 ORE 10:00 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre Largo San Leonardo Murialdo,1 - Pal.C - Aula 211 Abstract The arboreal gas is a probability measure that arises from conditioning the random subgraph given by Bernoulli(p) bond percolation to be a spanning forest, i.e., to contain no cycles. This conditioning makes sense on any finite graph G, and specializes to the uniform measure on spanning forests when p = 1/2. One is naturally lead to ask about the percolative properties of the arboreal gas, and this turns out to be a surprisingly rich question. I will discuss some results and conjectures about the arboreal gas, most of which are based on important relations between the arboreal gas and spin systems with hyperbolic symmetry. Based on joint work in progress with Roland Bauerschmidt, Nick Crawford, and Andrew Swan.

Economists For Future (fwd)
by Tiziano Vargiolu 02 Dec '19

02 Dec '19

Per completezza: c'e' una cosa molto importante che non viene detta sotto, ma nella procedura di firma si', ed e' questa: IMPORTANT: This open letter is open to everyone to sign, not just economists! Cordiali saluti a tutti ---------- Forwarded message ---------- Date: Mon, 02 Dec 2019 13:16:12 +0000 From: Luisa Jentsch <noreply(a)econ4future.org> Reply-To: info(a)econ4future.org To: Tiziano <vargiolu(a)math.unipd.it> Subject: Economists For Future Dear Tiziano, I write to introduce you to Economists for Future?s open letter that is calling on the economics community to raise its game and devise a more impactful contribution to tackling climate change. Economists for Future is an international student-led organisation with the aim to put pressure on the economics community to treat climate change like the emergency it is. While many economists have shown great academic leadership on this issue, the overall contribution from the community has not been commensurate with the magnitude of the problem. The shortage of climate change related articles in top journals is one such demonstration. For example, the most-cited journal in our discipline has never published an article on climate change [https://lists.econ4future.org/links/iJ9AW4JXP/PfQP6QyMO/aMbvBGRdzdg/YJmX2li…] As the next generation of economists, as young people who will live through the most severe climate effects and as individuals with a deep belief in the power of good economics to make the world a better place, we feel an acute pressure to ?do more? that we are hoping you will share. We think economists have both a responsibility and an enormous opportunity to have an even greater contribution to help tackle this emergency. The open letter (attempts to) make the case for economists seizing this opportunity to provide the intellectual framework that enables a rapid decarbonisation that is coupled with a great leap in human progress. We would like to invite you to support this initiative by signing the letter, which you can do by filling out the form on our website. [https://lists.econ4future.org/links/iJ9AW4JXP/PfQP6QyMO/aMbvBGRdzdg/K8_4G0o…] And, if you agree with it, we would kindly ask you to share your support among your social and academic networks. If you have any questions about our initiative or the letter, we would love to hear from you ? at the end of the day, we are curious students that desire more from the discipline we want to dedicate our lives to. Kind Regards, Luisa Jentsch Economists For Future Website: econ4future.org [econ4future.org] Facebook [https://lists.econ4future.org/links/iJ9AW4JXP/PfQP6QyMO/aMbvBGRdzdg/CY-m9M0…] Instagram [https://lists.econ4future.org/links/iJ9AW4JXP/PfQP6QyMO/aMbvBGRdzdg/qHhHAzS…] Twitter [https://lists.econ4future.org/links/iJ9AW4JXP/PfQP6QyMO/aMbvBGRdzdg/zMI73YS…]

Seminario Prof. Claudio Macci

Il Prof. Claudio MACCI dell'Università di Roma Tor Vergata mercoledì 4 dicembre 2019 alle ore 16 nell'Aula E al III livello del Dipartimento di Matematica e Applicazioni dell'Università degli Studi di Napoli Federico II terrà un seminario dal titolo: Large deviations for risk measures in finite mixture models ABSTRACT Due to their heterogeneity, insurance risks can be properly described as a mixture of different fixed models, where the weights assigned to each model may be estimated empirically from a sample of available data. If a risk measure is evaluated on the estimated mixture instead of the (unknown) true one, then it is important to investigate the committed error. In this paper we study the asymptotic behaviour of estimated risk measures, as the data sample size tends to infinity, in the fashion of large deviations. We obtain large deviation results by applying the contraction principle, and the rate functions are given by a suitable variational formula; explicit expressions are available for mixtures of two models. Finally, our results are applied to the most common risk measures, namely the quantiles, the expected shortfall and the shortfall risk measure. Joint work with Valeria Bignozzi and Lea Petrella.

Avviso di Seminario, università di Trento Stochastic homogenization in amorphous media and applications to interacting particle systems and random resistor networks Giovedì 5 dicembre 2019 Luogo: Polo Ferrari 1, via Sommarive, 5 - Povo (TN) - Aula A221 Ore: 16:00 Relatore: Alessandra Faggionato (Università La Sapienza, Roma) Abstract: We consider random walks on marked simple point processes with symmetric jump rates and unbounded jump range. Examples are given by simple random walks on Delaunay triangulations or Mott variable range hopping in doped semiconductors. We present homogenization results for the associated Markov generators. As a first application, we obtain the hydrodynamic limit of the exclusion process given by multiple random walks as above, with hard–core interaction. As a second application, we derive a limit theorem for the effective conductivity of some classes of random resistor networks. This result together with a percolation-type analysis allows to derive the low temperature scaling behavior of conductivity in some classes of strongly disordered media.

Seminar Berthet @Bocconi
by Giacomo Zanella 25 Nov '19

25 Nov '19

We announce the following DEC Statistics seminar: Thursday, November 28 12:30 Meeting room 3-e4-sr03, Bocconi University, Via Roentgen 1, 3rd floor Quentin Berthet (Google Research) Title: Optimal transport methods in statistics and machine learning: theory and applications Abstract: Optimal transport is one of the foundational problems of optimization, and a very important topic in analysis. It asks how one can transport mass with a given measure to have another measure, with minimal global transport cost. The associated Wasserstein distance is a useful statistical tool to compare distributions, taking into account geometric properties of the data. In this presentation, I will talk about two recent projects on this topic. In the first one, we propose a novel approach for unsupervised embedding alignment, and show applications to natural language processing. It is based on a new approach for Wasserstein loss minimization (joint work with E. Grave and A. Joulin). In the second one, we provide new methods and guarantees for estimation of distributions with smooth densities, in the Wasserstein distance. We show that these tools, inspired by techniques in nonparametric statistics, yield information-theoretic optimal results. We also develop ideas to handle our proposed estimators in a computationally efficient manner, and explore some of the associated computational trade-offs (joint work with J. Weed). Kind regards, Giacomo Zanella The DEC statistics seminars schedule is available at http://www.unibocconi.eu/statseminar Please note: if you are a guest and you do not have a Bocconi ID Card to access to the Bocconi Buildings, please communicate your participation by sending an email to elisa.picassi(a)unibocconi.it

PEANO" UNIVERSITÀ DEGLI STUDI DI TORINO ********************************************************************* Giovedì 5 Dicembre 2019 alle ore 14:00 nell'aula Magna del Dipartimento di Matematica "G. Peano" dell'Università degli Studi di Torino, Via Carlo Alberto 10, Il Prof. *Pierre Patie* (Cornell University, Ithaca, NY, USA) terrà un seminario dal titolo *Completely monotone intertwining relations* Abstract: In this talk, we introduce the concept of completely monotone intertwining relations as a strengthening of usual intertwining relations between Markov semi-groups. We proceed by providing some interesting applications of this new idea which includes the characterization of ergodic constants and hypercontractivity estimates for non-self-adjoint semigroups. We illustrate these results by presenting several examples that have emerged from the recent literature: discrete-to-continuous interacting particle models, degenerate hypoelliptic Ornstein-Uhlenbeck processes, and diffusion-to-jump Jacobi processes. This talk is based on a joint a work with L. Miclo (IMT Toulouse). Tutti gli interessati sono invitati a partecipare.

STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO Venerdì 29 Novembre 2019, alle ore 12:00, presso il nuovo edificio del Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Robin RYDER (Université Paris Dauphine) A BAYESIAN NON-PARAMETRIC METHODOLOGY FOR INFERRING GRAMMAR COMPLEXITY Based on a set of strings from a language, we wish to infer the complexity of the underlying grammar. To this end, we develop a methodology to choose between two classes of formal grammars in the Chomsky hierarchy: simple regular grammars and more complex context-free grammars. To do so, we introduce a probabilistic context-free grammar model in the form of a Hierarchical Dirichlet Process over rules expressed in Greibach Normal Form. In comparison to other representations, this has the advantage of nesting the regular class within the context-free class. We consider model comparison both by exploiting this nesting, and with Bayes’ factors. The model is fit using a Sequential Monte Carlo method, implemented in the Birch probabilistic programming language. We apply this methodology to data collected from primates, for which the complexity of the grammar is a key question. (joint work with L. Murray, J. Rousseau and A. Thin) ------------------------------------------------ Tutti gli interessati sono invitati a partecipare.

Seminar Wadsworth @Bocconi
by Giacomo Zanella 18 Nov '19

18 Nov '19

We announce the following DEC Statistics seminar: Thursday, November 21 12:30 Meeting room 3-e4-sr03, Bocconi University, Via Roentgen 1, 3rd floor Jenny Wadsworth (Lancaster University) Title: Towards higher-dimensional spatial and spatio-temporal extremes Abstract: The past decade has seen a huge effort in modelling the extremes of spatial processes. Significant challenges include the development of models with an appropriate asymptotic justification for the tail; ensuring model assumptions are compatible with the data; and the fitting of these models to (at least reasonably) high-dimensional datasets. I will review basic ideas of modelling spatial extremes, and introduce a more scalable approach via conditioning on a single site being extreme, which can also be applied in the space-time context. Furthermore, the sometimes-undesirable nature of conditioning on an extreme event at a particular location can be circumvented by an importance sampling algorithm to change the conditioning event. As we move towards being able to model extremes at more locations, we must also learn to deal with the complex structures of larger datasets, such as spatial nonstationarity in the extremal dependence. Some approaches to simplify these structures via deformations tailored to extremal dependence will also be discussed. Kind regards, Giacomo Zanella The DEC statistics seminars schedule is available at http://www.unibocconi.eu/statseminar Please note: if you are a guest and you do not have a Bocconi ID Card to access to the Bocconi Buildings, please communicate your participation by sending an email to elisa.picassi(a)unibocconi.it

Seminar: okada@DISMEQ Department of Statistics and Quantitative Methods, University of Milano-Bicocca
by Fulvia Pennoni 18 Nov '19

18 Nov '19

----------------------------------------------------------------------------------- ** 21/11/2019 h.11.00 /Building U7 4th floor - Seminar Room 4026/ Department of Statistics and Quantitative-Methods, Via Bicocca degli Arcimboldi, 8 - 20126 Milano ----------------------------------------------------------------------------- MULTIDIMENSIONAL SCALING OF ASYMMETRIC RELATIONSHIPS Akinori Okada Professor Emeritus of the Rikkyo University, Tokyo okada(a)rikkyo.ac.jp Torgerson (1952) introduces his multidimensional scaling as the first practical method of representing proximity (similarity, dissimilarity) relationships among objects in a multidimensional space or a configuration. The method is called metric, which means that the observed proximities are assumed to be interval or ratio scaled values. Shepard (1962a, b) and Kruskal (1964a, b) introduced methods which are called nonmetric multidimensional scaling. Nonmetric multidimensional scaling assumes that the observed proximities are ordinal scaled values. This mean that only the information which of two proximities is larger (or smaller) than the other is utilized in the analysis. The nonmetric multidimensional scaling of Kruskal (1964a, b) has been used most frequently in practical applications of multidimensional scaling, and several multidimensional scaling methods based on the similar idea of Kruskal (1964a, b) have been introduced. The multidimensional scaling developed so far assumes that the proximity is symmetric. Several researchers focused their attention on the asymmetry in various sorts of proximity; similarity/dissimilarity judgment, same/different judgment, reaction time, social and psychological distance, and so on. It is meaningful to develop asymmetric multidimensional scaling which can represent asymmetric proximity relationships among objects in a configuration. Various kinds of procedures to analyze an asymmetric proximity matrix were invented. We concentrate on the multidimensional scaling which is based on the distance among points, each representing an object, in a multidimensional space (distance model). The asymmetric multidimensional scaling by Okada and Imaizumi (1987) represents asymmetric proximity relationships among objects by the interpoint distance in a multidimensional configuration. The distance between two points is symmetric. It is difficult to represent asymmetric relationships simply by the interpoint distance, because the distance itself is symmetric. The model of Okada and Imaizumi (1987), which is called Distance-radius model, represents an object by a point and a circle [two-dimensional model] (sphere [three-dimensional] or hypersphere [larger than three-dimensional]) centered at the point in a multidimensional space. Several models were derived from the model. Multidimensional scaling mentioned above, regardless of metric or nonmetric and of being able to represent asymmetry or not, analyzes one proximity matrix (object x object) or one-mode two-way proximities (Carroll and Arabie, 1980). To analyze a set of proximity matrices each comes from a source (object x object x source) or two-mode three-way proximities, INDSCAL was developed by Carroll and Chang (1970). INDSCAL can represent relationships among objects and how each source (individual) has different relationships among objects each other. While INDSCAL can represents differences among sources, it cannot represent the asymmetry in relationships among objects of each source. The model of Okada and Imaizumi (1997) is an extension of the Distance-radius model which can analyze a set of asymmetric proximity matrices or two-mode three-way asymmetric proximities. The asymmetric multidimensional scaling of Okada and Imaizumi (1997) can represents asymmetric relationships among objects, and how each source has different symmetric and asymmetric relationships among objects each other as well. Several models, which are less restricted or more restricted, have been derived from Okada and Imaizumi (1997). To analyze one-mode two-way asymmetric proximities, there is another asymmetric multidimensional scaling by Okada (2011) and Okada and Tsurumi (2012) which is based on the singular value decomposition. The asymmetric multidimensional scaling has been utilized to analyze mainly the data from marketing research or brand switching. Several models and procedures have been derived by extending the model of Okada (2011) which can, for example, evaluate newly introduced brands, diagnose brands, tell how to increase the dominance of a brand in the brand switching... Another sort of procedure to analyze one-mode two-way asymmetric proximities is asymmetric cluster analysis, which can represent asymmetric proximity relationships among objects by forming clusters (Okada & Iwamoto, 1966; Okada & Yokoyama, 2015). It is important and meaningful to develop not only multidimensional scaling but also cluster analysis as well so that we can use two different kinds of methods to analyze the same proximity data (Arabie & Hubert, 1994). There are quite a few number of applications of asymmetric multidimensional scaling and cluster analysis. While these applications are not mentioned here because of the space limitation, some of them will be mentioned in the talk. The present abstract deals only with researches of the author and his colleagues. Bove and Okada (2018) gives a review which covers a wide range of asymmetric multidimensional scaling and asymmetric cluster analysis in detail. Some books mention the analysis of asymmetric relationships. Borg and Groenen (2005) has a chapter of asymmetric multidimensional scaling. Coxon and Coxon (2001) refers to asymmetric multidimensional scaling. **/References/// Arabie, P. & Hubert, L. (1994). Cluster analysis in marketing research. In Bagozzi, R. F.

A coloro che fossero interessati (per una migliore organizzazione) chiediamo di mandare un email a <mailto:francescaromana.nardi@unifi.it> francescaromana.nardi(a)unifi.it; <mailto:gianmarco.bet@unifi.it> gianmarco.bet(a)unifi.it; <mailto:angela.caporicci@unifi.it> angela.caporicci(a)unifi.it con l'intenzione di partecipare al seminario, al coffe break e al pranzo. PROGRAMMA Prof. Sabine Jansen (LMU Munich) Title: Large deviations and metastability for the Widom-Rowlinson model Abstract: The Widom-Rowlinson model is one of the few models in statistial mechanics for which a phase transition is rigorously proven. It is also popular in stochastic geometry and spatial statistics where it is called area interaction model and belongs to the broader class of quermass interaction models. After reviewing some relevant background about Gibbs measures for continuum interacting particle systems, I will discuss large deviations for the Widom-Rowlinson model in a joint high-density / low-temperature limit. I will also discuss metastability for a spatial birth and death process, a.k.a. continuum Glauber or grand-canonical Monte-Carlo, for which the Gibbs measure is reversible. Based on joint work with Frank den Hollander, Roman Kotecký and Elena Pulvirenti. Prof. Luca Avena (University of Leiden) Title: Explorations of networks through random spanning forests: theory and applications Abstract: David Wilson in the 1990s described a simple and efficient algorithm based on loop-erased random walks to sample uniform spanning trees and, more generally, weighted rooted trees or forests spanning a given graph. The goal of this lecture is to describe the resulting probability measure when Wilson's algorithm is used to sample rooted spanning forests. This forest-measure has a rich, flexible and explicit mathematical structure which makes it a powerful tool to design different algorithms to explore a given network. In the first part of the lecture, I will focus on fundamental aspects of this measure and how it relates to other objects of interest in statistical physics such as the well known Random-cluster model. I will in particular describe the main properties of related observables (e.g. set of roots, induced partition) which turn out to be determinantal processes with simple kernels and then discuss some progress in understanding related scaling limits. The second part of the lecture will be devoted to applications. In particular, depending on time, I plan to discuss four different algorithms aiming at: (1) sampling well-distributed points in a graph, (2) coarse-graning a given network, (3) processing signals on graphs (a novel gaph wavelet transform), (4) estimating the spectrum of the graph Laplacian. The core of this lecture is based on different joint collaborations with the following colleagues and students: Castell, Gaudillere, Melot, Milanesi (Marselle), Quattropani (Rome), Driessen, Koperberg, Magrini (Leiden) , Amblard, Barthelme, Tremblay (Grenoble).

Seminario Luca Avena a Pisa
by Dario Trevisan 13 Nov '19

13 Nov '19

Dear all, this is to announce the following research talk by Luca Avena, to be held in Pisa. PLACE: Aula Riunioni, Dipartimento di Matematica, Università di Pisa (first floor). DATE & TIME: Wednesday, Nov 20, 2019, 2 PM SPEAKER: Luca Avena (Univ. Leiden) TITLE: Multiscale analysis of network data sets via random walk kernels. ABSTRACT: I will present a random walk approach to analyse data sets that are encoded into a network structure (a weighted graph). Random walks are natural objects to explore a given network and have been used as building blocks to design different type of algorithms such as the celebrated PageRank. The core of this lecture is on three new general algorithms aiming at: 1) sampling well-distributed points in a graph, 2) coarse graining a given network at different scales, 3) processing signals on graphs through a novel wavelets transform. As I will discuss, these algorithms can be good or not depending on the specific data set problem to be analyzed. The main emphasis will be given on the underlying mathematical structures which are of fundamental interest per se within probability theory and statistical phyisics. Partially based on joint work with Castell, Gaudilliere and Melot Best regards, Dario -- Dario Trevisan, Università degli Studi di Pisa, Dipartimento di Matematica, Largo Bruno Pontecorvo 5, 56127 - Pisa (PI) Italy telephone: (+39) 050 2213832 mobile: (+39) 331 2899761 Skype: dario-trevisan e-mail: dario.trevisan AT unipi.it webpage: http://people.dm.unipi.it/trevisan/

AN``AUTUMN'' DAY IN PROBABILITY AND STATISTICAL PHYSICS - 22 November 2019 (Jansen e Avena)
by Francesca Romana Nardi 07 Nov '19

07 Nov '19

Carissimi, Vi annunciamo che prossimamente si terrà la nona giornata di seminari: AN ``AUTUMN'' DAY IN PROBABILITY AND STATISTICAL PHYSICS University of Florence Friday 22 November 2019 Lecturers: Sabine Jansen (Munich) and Luca Avena (Leiden) Location: Aula Tricerri Viale Morgagni 67, Firenze Informazioni su come arrivare alla pagina: <https://www.dimai.unifi.it/vp-285-come-arrivare-how-to-get.html> https://www.dimai.unifi.it/vp-285-come-arrivare-how-to-get.html Note pratiche: Stiamo prenotando un catering con cibi vegerariani e non, percio` abbiamo bisogno del numero di persone che vogliono mangiare insieme. A coloro che fossero interessati (per una migliore organizzazione) chiediamo di mandare un email a <mailto:francescaromana.nardi@unifi.it> francescaromana.nardi(a)unifi.it; <mailto:gianmarco.bet@unifi.it> gianmarco.bet(a)unifi.it; <mailto:angela.caporicci@unifi.it> angela.caporicci(a)unifi.it con l'intenzione di partecipare al seminario, al coffe break e al pranzo. PROGRAMMA Prof. Sabine Jansen (LMU Munich) Title: Large deviations and metastability for the Widom-Rowlinson model Abstract: The Widom-Rowlinson model is one of the few models in statistial mechanics for which a phase transition is rigorously proven. It is also popular in stochastic geometry and spatial statistics where it is called area interaction model and belongs to the broader class of quermass interaction models. After reviewing some relevant background about Gibbs measures for continuum interacting particle systems, I will discuss large deviations for the Widom-Rowlinson model in a joint high-density / low-temperature limit. I will also discuss metastability for a spatial birth and death process, a.k.a. continuum Glauber or grand-canonical Monte-Carlo, for which the Gibbs measure is reversible. Based on joint work with Frank den Hollander, Roman Kotecký and Elena Pulvirenti. Prof. Luca Avena (University of Leiden) Title: Explorations of networks through random spanning forests: theory and applications Abstract: David Wilson in the 1990s described a simple and efficient algorithm based on loop-erased random walks to sample uniform spanning trees and, more generally, weighted rooted trees or forests spanning a given graph. The goal of this lecture is to describe the resulting probability measure when Wilson's algorithm is used to sample rooted spanning forests. This forest-measure has a rich, flexible and explicit mathematical structure which makes it a powerful tool to design different algorithms to explore a given network. In the first part of the lecture, I will focus on fundamental aspects of this measure and how it relates to other objects of interest in statistical physics such as the well known Random-cluster model. I will in particular describe the main properties of related observables (e.g. set of roots, induced partition) which turn out to be determinantal processes with simple kernels and then discuss some progress in understanding related scaling limits. The second part of the lecture will be devoted to applications. In particular, depending on time, I plan to discuss four different algorithms aiming at: (1) sampling well-distributed points in a graph, (2) coarse-graning a given network, (3) processing signals on graphs (a novel gaph wavelet transform), (4) estimating the spectrum of the graph Laplacian. The core of this lecture is based on different joint collaborations with the following colleagues and students: Castell, Gaudillere, Melot, Milanesi (Marselle), Quattropani (Rome), Driessen, Koperberg, Magrini (Leiden) , Amblard, Barthelme, Tremblay (Grenoble). Program: 11.00-11.45 Introductory lecture: Jansen 11.45-12.00 Break 12.00-12.45 Seminar: Jansen 13.00-14.30 Lunch 14.30-15.15 Introductory lecture: Avena 15.15-15.30 Break 15.30-16.30 Seminar: Avena Organizers: G.

30 Oct '19

Dear all, I would like to announce the following talk that will be held on Thursday *November* *7th* 2019, at *5 PM*, in *Aula D’Antoni* of the Department of Mathematics, University of Rome Tor Vergata. *Speaker:* Emilio Porcu (Trinity College Dublin) *Title:* Modeling Temporally Evolving and Spatially Globally Dependent Data *Abstract:* The last decades have seen an unprecedented increase in the availability of data sets that are inherently global and temporally evolving, from remotely sensed networks to climate model ensembles. This paper provides an overview of statistical modeling techniques for space–time processes, where space is the sphere representing our planet. In particular, we make a distinction between (a) second order‐based approaches and (b) practical approaches to modeling temporally evolving global processes. The former approaches are based on the specification of a class of space–time covariance functions, with space being the two‐dimensional sphere. The latter are based on explicit description of the dynamics of the space–time process, that is, by specifying its evolution as a function of its past history with added spatially dependent noise. We focus primarily on approach (a), for which the literature has been sparse. We provide new models of space–time covariance functions for random fields defined on spheres cross time. Practical approaches (b) are also discussed, with special emphasis on models built directly on the sphere, without projecting spherical coordinates onto the plane. We present a case study focused on the analysis of air pollution from the 2015 wildfires in Equatorial Asia, an event that was classified as the year's worst environmental disaster. The paper finishes with a list of the main theoretical and applied research problems in the area, where we expect the statistical community to engage over the next decade. Kind regards, Anna Vidotto --------- Anna Vidotto PostDoc Researcher Dipartimento di Matematica Università degli Studi di Roma Tor Vergata https://sites.google.com/view/annavidotto

A revolution in statistics and machine learning (ML) is underway. Modern algorithms can now learn high level abstractions via hierarchical models, leading to break-through accuracy in benchmarks for computer vision, language, etc. Underlying these advances is a strong and deep connection to various aspects of applied mathematics and statistical physics. For example, proper choice of statistical force allows to screen interaction and learn graphical models governing multi-dimensional distributions efficiently, gauge transformations from physics guide incorporation of symmetries in the neural network design, dynamical system interpretation helps to understand and improve performance of most efficient deep learning schemes, etc. This workshop seeks perspectives on leveraging the deep connection between ML and physics, but now with the goal to better understand and model physical systems, static and dynamic. We invite experts both in machine learning techniques as well as domain science applications. In this third edition of PIML we will focus on applications of interest to our LANL and DOE sponsors, specifically on improving scale-reduced, large eddy modeling and simulations of turbulence that arise in various mechanical-engineering, aerospace and climate applications; building reduced models for infrastructures (energy systems, cyber-physical systems, etc.); guiding development of inverse/design approaches in quantum physics, e.g. related to tensor networks; designing new computational paradigms (such as related to quantum and neuromorphic computing). The workshop discussions are aimed towards approaches and methods for physical modeling applications where a big-data, black-box approach to ML is only a starting point. We seek participants who may suggest innovative approaches that extend application agnostic ML techniques by incorporating complex constraints imposed by physical principles (e.g. conservation laws, causality, symmetries, entropy principles and related). The workshop format assumes 7 talks a day, late afternoon discussions and poster session. We encourage application of young researchers for fellowships (see website for details). We plan for active participation of LANL researchers and program managers across directorates and divisions interested in the physics informed learning. This emerging area of research has many aspects of computational co-design, and draws on LANL's strengths in statistical physics, modern applied mathematics, theoretical and applied computer science, infrastructure modeling and simulations, fluids and materials modeling, and high performance computing. Looking forward, we view physics informed learning as a viable path for LANL and DOE toward truly predictive multi-scale modeling, optimization, inference and leading for plethora of relevant applications in sciences and engineering. *Organizing Committee:* Michael Chertkov (University of Arizona) Andrey Lokhov (Los Alamos National Laboratory) Arvind Mohan (Los Alamos National Laboratory) [image: bed3f21384084acb905f2c173a3fa658.jpg]

seminario Claudio Macci a Pisa
by Dario Trevisan 28 Oct '19

28 Oct '19

Dear all, this is to announce the following research talk by Claudio Macci, to be held in Pisa. PLACE: Sala Seminari, Dipartimento di Matematica, Università di Pisa (first floor). DATE & TIME: Wednesday, Nov 6, 2019, 3 PM SPEAKER: Claudio Macci (Università Roma Tor Vergata) TITLE: Multivariate fractional (possibly compound) Poisson processes ABSTRACT: we present multivariate space-time fractional Poisson processes by considering common random time-changes of a finite-dimensional vector of independent classical (nonfractional) Poisson processes. In some cases we also consider compound processes. We obtain some equations in terms of some suitable fractional derivatives and fractional difference operators, which provides the extension of known equations for the univariate processes. In particular we show that, for each fixed $t\geq 0$, the conditional joint distribution of the components given their sum is multinomial, as happens for the nonfractional Poisson processes. Thus we consider a suitable multivariate "alternative" fractional Poisson process, and we study its asymptotic behavior for large times (large and moderate deviations). The results appear in two papers with Luisa Beghin.

Seminario a Padova: Alekos Cecchin

Seminario di Analisi e Probabilità all'Università di Padova Martedì 29 ottobre 2019 alle ore 14:30 in aula seminario 430 del Dipartimento di Matematica (via Trieste, 63, 35121 Padova) Alekos Cecchin (Université de Nice Sophia-Antipolis, France) terrà un seminario dal titolo "Selection by vanishing common noise for potential finite state mean field games" Abstract: By adding a suitable Wright-Fisher common noise in the dynamics of the law, uniqueness is restored for finite state mean field games, for any shape of the costs. We then focus on a class of mean field games in which the costs admit a potential in the simplex of probability measures. Firstly, by modifying the cost in the mean field game, we show that the unique solution of the randomized mean field game is equal to the unique minimizer of a suitable stochastic control problem stated in the simplex, called potential randomized game. Thus we study the limit as the intensity of the common noise vanishes. On the one hand, the optimal trajectories converge to the mean field game solutions which are minimizers of the corresponding potential game (not randomized), that is a deterministic optimal control problem in the simplex. On the other hand, the classical solution to the second order master equation converges to the gradient of the value function of the related potential game; we select a particular weak solution, in the sense of distributions, of the master equation, which can be written as multidimensional system of hyperbolic PDEs stated in the simplex. Lastly, we establish uniqueness of such solution in a suitable class. Joint work with Francois Delarue. Tutti gli interessati sono invitati a partecipare.

Seminario di probabilita' di Daniel Valesin (Groningen) a Roma Tre
by Alexandre Stauffer 24 Oct '19

SEMINARIO Probabilita' Daniel Valesin (University of Groningen) Titolo: On the threshold of spread-out contact process percolation Lunedi' 04 Novembre 2019 ORE 16:30 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre Largo San Leonardo Murialdo,1 - Pal.C - Aula 211 Abstract We study the stationary distribution of the (spread-out) d-dimensional contact process from the point of view of site percolation. In this process, vertices of ^d can be healthy (state 0) or infected (state 1). With rate one infected individuals recover, and with rate lambda they transmit the infection to some other vertex chosen uniformly within a ball of radius R. The classical phase transition result for this process states that there is a critical value lambda_c(R) such that the process has a non-trivial stationary distribution if and only if lambda > lambda_c(R). In configurations sampled from this stationary distribution, we study nearest-neighbor site percolation of the set of infected sites; the associated percolation threshold is denoted lambda_p(R). We prove that lambda_p(R) converges to 1/(1-p_c) as R tends to infinity, where p_c is the threshold for Bernoulli site percolation on ^d. As a consequence, we prove that lambda_p(R) > lambda_c(R) for large enough R, answering an open question of [Liggett, Steif, AIHP, 2006] in the spread-out case. Joint work with Bala'zs Ra'th.

Mini corso di A. Stauffer a Roma Tre: Multi-scale analysis of reaction-diffusion particle systems
by Pietro Caputo 22 Oct '19

22 Oct '19

Speaker: Alexandre Stauffer (Roma Tre) Title: Multi-scale analysis of reaction-diffusion particle systems 6 Lectures: Monday, 25 November at 16:30 Tuesday, 26 November at 14:30 Monday, 2 December at 16:30 Tuesday, 3 December at 14:30 Monday, 9 December at 16:30 Tuesday, 10 December at 14:30 All lectures will be in Room 211 (2nd floor) at Department of Mathematics and Physics of Roma Tre Largo San Murialdo 1, Palazzina C For PhD students that want to take the course as part of their PhD coursework, the course will be completed by a reading part (to be discussed with the lecturer). Abstract: This course focus on the (microscopic) analysis of stochastic processes on particle systems. A few examples include spread of infection among moving particles, the frog model or stochastic combustion model, activated random walks, growth processes with competition, and branching random walk with interactions. A common feature of such models is that correlations do not decay exponentially fast, which brings serious challenges to the application of standard techniques of analysis, such as renormalization techniques and comparison with independent percolation. Recently, there has been very important progress in this field, with most new results employing a so-called multi-scale analysis to control the dependences in the model. Multi-scale analysis proved to be an extremely powerful technique; it has been employed in areas beyond particle system, one notable example being the study of random interlacements, where it has been playing a fundamental role. Despite its power, a multi-scale analysis can be quite involved to implement and can become very technical. In particular, it usually needs to be developed from scratch for each application as it needs to be tailored to each specific question being analyzed. The goal of this course is to explain the multi-scale analysis in a didactic and comprehensible way, demystifying this technique, and explaining its main aspects (the ones that are common to most applications) and the most common variations. In order to do this we will concentrate on one problem: the analysis of the spread of an infection among particles that move as independent simple random walks.

Seminar Cadonna @Bocconi
by Giacomo Zanella 18 Oct '19

18 Oct '19

We announce the following DEC Statistics seminar: Thursday, October 24 12:30 Meeting room 3-e4-sr03, Bocconi University, Via Roentgen 1, 3rd floor Annalisa Cadonna (Wirtschaftsuniversität Wien) Title: Hierarchical shrinkage in time-varying parameter models through the Triple Gamma prior Abstract: Time varying parameter (TVP) models are widely used in time series analysis, because of their flexibility and ability to capture gradual changes in the evolution dynamics of the model variables. The popularity of TVP state-space models in macroeconomics and finance is based on the evidence that, in most applications, the influence of certain predictors on the outcome variables varies over time. The risk of overfitting in TVP models is a well know issue, which increases with the dimension of the problem at hand, as only a small subset of the predictors might actually have a dynamic influence on the output variables. Hence, in the last decade, there has been a growing need for models and methods able to discriminate between time varying and static parameters in TVP models or, in other words, perform variance selection. We propose a new global local shrinkage prior for shrinkage of variances in TVP models, referred to as the Triple Gamma prior. The Triple Gamma prior extends to variance selection the Normal-Gamma-Gamma prior introduced in Griffin and Brown (2017) in the context of highly structured regression models. The Triple Gamma prior accommodates, as special or limit cases, the Bayesian Lasso, the Double Gamma prior, and the popular Horseshoe prior. Interesting properties of the triple gamma prior are outlined and an efficient Markov Chain Monte Carlo algorithm is developed. An extended simulation study is conducted and the proposed modeling approach is applied to real data, both in a univariate and a multivariate framework. The predictive performance of different shrinkage priors is compared in terms of log predictive density scores. Kind regards, Giacomo Zanella The DEC statistics seminars schedule is available at http://www.unibocconi.eu/statseminar Please note: if you are a guest and you do not have a Bocconi ID Card to access to the Bocconi Buildings, please communicate your participation by sending an email to arianna.colombo(a)unibocconi.it

Spring School COMPLEX NETWORKS: THEORY, METHODS, AND APPLICATIONS (6th edition)

Spring School COMPLEX NETWORKS: THEORY, METHODS, AND APPLICATIONS (6th edition) Lake Como School of Advanced Studies Villa del Grumello, Como, Italy, 18-21 May 2020 https://ntmf.lakecomoschool.org/ *** DEADLINE FOR APPLICATION: February 23, 2020 *** Many real systems can be modeled as networks, where the elements of the system are nodes and interactions between elements are edges. An even larger set of systems can be modeled using dynamical processes on networks, which are in turn affected by the dynamics. Networks thus represent the backbone of many complex systems, and their theoretical and computational analysis makes it possible to gain insights into numerous applications. Networks permeate almost every conceivable discipline---including sociology, transportation, economics and finance, biology, and myriad others---and the study of "network science" has thus become a crucial component of modern scientific education. The school "Complex Networks: Theory, Methods, and Applications" offers a succinct education in network science. It is open to all aspiring scholars in any area of science or engineering who wish to study networks of any kind (whether theoretical or applied), and it is especially addressed to doctoral students and young postdoctoral scholars. The aim of the school is to deepen into both theoretical developments and applications in targeted fields.

Colloquium di Lorenzo Zambotti a Milano-Bicocca (lunedì 28 ottobre)
by Francesco Caravenna 15 Oct '19

15 Oct '19

Ho il piacere di annunciare il seguente Colloquium del Dipartimento di Matematica e Applicazioni, Università di Milano-Bicocca, congiuntamente con il Seminario Matematico e Fisico di Milano. Il giorno lunedì 28 ottobre 2019, alle ore 16:00, Lorenzo Zambotti (Sorbonne Université, Paris) terrà un colloquium dal titolo "Regularity structures: from physics to probability, from analysis to algebra, from combinatorics to geometry" Il seminario si terrà nell'aula 3014 (edificio U5, terzo piano, via Cozzi 55, Milano) e sarà seguito da un rinfresco. Segue l'abstract. Tutti gli interessati sono invitati a partecipare. Francesco Caravenna %%%%%%%%%%%%%%%%%%%%%%%%%%%% Abstract: In this talk I wish to present some of the ideas at the heart of the theory of regularity structures (RS), introduced by Martin Hairer in 2014. RS are perhaps best described as a theory of Taylor expansions in a fractal (random) setting. I plan to show how this theory is based on a fascinating interplay between several different disciplines, as announced by my title. %%%%%%%%%%%%%%%%%%%%%%%%%%%% _________________________________________ Francesco Caravenna Dipartimento di Matematica e Applicazioni Università degli Studi di Milano-Bicocca Via Cozzi 55, 20125 Milano, Italy http://www.matapp.unimib.it/~fcaraven/ _________________________________________

Looking forward to your participation, Fabio Ancona, Paolo Dai Pra, Franco Rampazzo ---------------------------------------------------------------- *** Half day in Stochastic Analysis and applications *** Wed. 30 Oct. 2019, Aula 1C150 Maths Department, Padova ---------------- *** Special Guest: THERRY LYONS (Oxford) *** *** Opening the workshop at 10:30*** ---------------- *** Speaker: FRANCO FLANDOLI (SNS Pisa)*** *** Seminar at 11:05*** *** Title: Effect of transport noise on PDEs *** *** Abstract *** Linear PDEs of transport type are regularized by the addition of an extra transport term of stochastic type; this is a phenomenon discovered around 2010 and consolidated by different techniques and on different examples. However, the effect on nonlinear PDEs is much less clear. Two results for point vortex solutions and point charge solutions of 2D Euler equations and 1D Vlasov-Poisson equations respectively, indicate that a rich noise has to be considered, opposite to the linear case where a simple space-independent noise suffices to regularize. Some confirmations that such rich noise may have regularizing properties on nonlinear models came for Leray alpha model and dyadic models of turbulence. We now have new insight in the case of 2D Euler equations and 3D Navier-Stokes equations, that will be explained in the talk. The results mentioned above, the classical and the new ones, have been obtained by several authors including Gubinelli, Priola, Barbato, Galeati, Luo and myself. ---------------- *** Speaker: FRANCESCO CARAVENNA (Milano Bicocca) *** *** Seminar at 11:40 *** *** Title: On the two-dimensional KPZ equation *** *** Abstract: *** We consider the Kardar-Parisi-Zhang (KPZ) equation in two space dimensions, driven by space-time white noise. This is a singular PDE which lacks a solution theory, so it is standard to consider a regularized version of the equation and then to investigate the behavior of the solution when the regularization is removed. We first show that the regularized solution undergoes a phase transition, as the noise strength is varied on a logarithmic scale. Then, in the sub-critical regime, we prove convergence (after centering and rescaling) to an explicit well-posed random PDE, the additive Stochastic Heat Equation, with a non-trivial constant on the noise. Based on joint works with Rongfeng Sun and Nikos Zygouras. ---------------- *** Speaker: FRANCO RAMPAZZO (Padova) *** *** Seminar at 12:15 *** *** Title: Limit solutions for control-affine nonlinear systems of ode's *** *** Abstract: *** The aim of this talk, which is fully devoted to deterministic input-output systems, is to present the extremely weak notion of 'limit solution', that might be (or might be not) of interest also for whom is more interested in Stochastic Analysis. For a nonlinear (deterministic) control system with a given initial condition and with a dynamics which is affine in the control variable, a 'limit solution' verifies the following properties: i) it is pointwise defined for an input which is (formally) the derivative of a Lebesgue integrable function; ii) in the commutative case (i.e. when all Lie brackets of the involved vector field vanish identically) the limit solution coincides with the solution one can obtain via a (existing) change of coordinates which makes all vector fields constant; iii) the notion of limit solution subsumes former concepts of solution valid for the generic, non-commutative case. In particular, when the control is the derivative of a bounded variation path, a quite clear relation is established between limit solutions and so-called 'graph completion' solutions.

Seminario di Antonio Blanca a Roma Tre il 24-10-2019

Speaker: Antonio Blanca (Penn State University) Titolo: Lower bounds for testing spin systems Giovedi' 24 Ottobre 2019 ORE 10:00 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre Largo San Leonardo Murialdo,1 - Pal.C - Aula 211 Abstract We study the identity testing problem in the context of spin systems where it takes the following form: given the parameter specification of the model M and a sampling oracle for the distribution μ of an unknown model M*, can we efficiently determine if the two models M and M* are the same? We establish hardness results for this problem for two prototypical spin systems: the Ising model and proper colorings. For the ferromagnetic (attractive) Ising model, Daskalakis et al. (2018) presented a polynomial-time algorithm for identity testing. I will present a hardness result for the antiferromagnetic (repulsive) setting. In our proofs, we use random graphs as gadgets; this is inspired by similar constructions in seminal works on the hardness of approximate counting. The results for proper colorings are based on the presumed hardness of #BIS, the problem of (approximately) counting independent sets in bipartite graphs. Based on joint work with Ivona Bezakova, Zongchen Chen, Daniel Stefankovic and Eric Vigoda

Despite the existing results on estimation of such objects through high frequency observations, the question of optimality is rarely discussed. We will demonstrate some optimal estimation methods for the supremum and local times of the Brownian motion in the L2 and L1 sense. In the second part of the talk we will investigate how the main ideas can be extended towards the class of Levy processes and continuous diffusion models. (joint work with J.

Peano" dell'Università degli Studi di Torino, Via Carlo Alberto 10, Il Prof. *Enrico Scalas* (Department of Mathematics – University of Sussex, UK) terrà un seminario dal titolo *Functional and Thermodynamic Limits of a Simple Coagulation-Fragmentation Markov Chain* Abstract: We discuss a simple random exchange model for the distribution of wealth. There are N agents, each one endowed with a fraction of the total wealth; indebtedness is not possible, so wealth fractions are positive random variables. At each step, two agent are randomly selected, their wealths are first merged (coagulation) and then randomly split into two parts (fragmentation) conserving the total wealth. We start from a discrete state space - discrete time version of this model and, under suitable scaling, we present its functional convergence to a continuous space - discrete time model. Then, we discuss how a continuous-time version of the one-point marginal Markov chain functionally converges to a kinetic equation of Boltzmann type. Solutions to this equation are presented and they coincide with the appropriate limits of the invariant measure for the marginal Markov chain. In this way, in this simple case, we complete Boltzmann’s program of deriving kinetic equations from random dynamics.

Martedi' 15 Ottobre 2019 ORE 14:30 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre Largo San Leonardo Murialdo,1 - Pal.C - Aula 211 Speaker: Jonathan Hermon Titolo: Anchored expansion in supercritical percolation on nonamenable graphs. Abstract: Let G be a transitive nonamenable graph, and consider supercritical Bernoulli bond percolation on G. We prove that the probability that the origin lies in a finite cluster of size n decays exponentially in n. We deduce that: 1. Every infinite cluster has anchored expansion (a relaxation of having positive Cheeger constant), and so is nonamenable in some weak sense. This answers positively a question of Benjamini, Lyons, and Schramm (1997). 2. Various observables, including the percolation probability and the truncated susceptibility (which was not even known to be finite!) are analytic functions of p throughout the entire supercritical phase. 3. A RW on an infinite cluster returns to the origin at time 2n with probability exp(-Theta(n^{1/3})). Joint work with Tom Hutchcroft.

Seminar Mealli @Bocconi

08 Oct '19

We announce the following DEC Statistics seminar: Thursday, October 10 12:30 Meeting room 3-e4-sr03, Bocconi University, Via Roentgen 1, 3rd floor Fabrizia Mealli (University of Florence) Title: Assessing causal effects in the presence of treatment switching through principal stratification Abstract: consider clinical trials focusing on survival outcomes for patients suffering from Acquired Immune Deficiency Syndrome (AIDS)-related illnesses or particularly painful cancers in advanced stages. These trials often allow patients in the control arm to switch to the treatment arm if their physical conditions are worse than certain tolerance levels. The Intention-To-Treat analysis compares groups formed by randomization regardless of the treatment actually received. Although it provides valid causal estimates of the effect of assignment, it does not measure the effect of the actual receipt of the treatment and ignores the information of treatment switching in the control group. Other existing methods propose to reconstruct the outcome a unit would have had if s/he had not switched. But these methods usually rely on strong assumptions, for example, there exists no relation between patient's prognosis and switching behavior, or the treatment effect is constant. Clearly, the switching status of the units in the control group contains important post-treatment information, which is useful to characterize the treatment effect heterogeneity. We propose to re-define the problem of treatment switching using principal stratification and introduce new causal estimands, principal causal effects for patients belonging to subpopulations defined by the switching behavior under control. For statistical inference, we use a Bayesian approach to take into account that (i) switching happens in continuous time generating infinitely many principal strata; (ii) switching time is not defined for units who never switch in a particular experiment; and (iii) survival time and switching time are subject to censoring. We illustrate our framework using a synthetic dataset based on the Concorde study, a randomized controlled trial aimed to assess causal effects on time to-disease progression or death of immediate versus deferred treatment with zidovudine among patients with asymptomatic HIV infection. Joint work with Alessandra Mattei and Peng Ding Kind regards, Giacomo Zanella The DEC statistics seminars schedule is available at http://www.unibocconi.eu/statseminar Please note: if you are a guest and you do not have a Bocconi ID Card to access to the Bocconi Buildings, please communicate your participation by sending an email to arianna.colombo(a)unibocconi.it

Seminar announcement
by Marco Scarsini 01 Oct '19

01 Oct '19

Thursday, 3 October, 12:00 Luiss | Viale Romania, 32 | Room 207 Yosi Rinott, Hebrew University of Jerusalem Title Priors and Posteriors of Asset Values, Domination, Optimism, and Monotonicity Abstract Suppose there is a set of states that are relevant to the value of an asset, and the market has a prior distribution on the state space. Consider signals having distribution depending on the true state. The price of an asset depends on the market’s posterior probability that the asset is in a good state, given a signal. Before the signal is given, the market considers the expectation of this (random) posterior probability, and more generally, its distribution. It is well known that the expected posterior equals the prior, but the actual posterior probability may be higher or lower than the prior depending on the signal. Suppose an insider has a different prior than the market. We study the question of what kind of priors will make the insider expect that the asset value following the signal will be higher than the market’s value (suggesting to buy, or to be optimistic). Since the posterior is a random variable, this leads to stochastic ordering, and in fact, we obtain a very strong ordering, namely likelihood ratio order. Given such a setup, if signals are generated independently according to a given state, then Doob’s Bayesian Consistency Theorem says that the posterior probability of this state converges to one. We study some monotonicity properties of this convergence, and some (perhaps) surprising lack of monotonicity. ******************************************************* Marco Scarsini Dipartimento di Economia e Finanza Luiss Viale Romania 32 00197 Roma, ITALY URL: http://docenti.luiss.it/scarsini/

Seminario di Claudio Macci presso l’Università di Salerno
by Barbara Martinucci 01 Oct '19

01 Oct '19

Il Prof. Claudio Macci (Università di Roma Tor Vergata) terrà il seguente seminario mercoledì 9 ottobre alle ore 16.00 presso la sala riunioni del Dipartimento di Matematica dell’Università di Salerno: *Titolo*: "Multivariate fractional (possibly compound) Poisson processes " *Abstract:* We present multivariate space-time fractional Poisson processes by considering common random time-changes of a finite-dimensional vector of independent classical (non fractional) Poisson processes. In some cases we also consider compound processes. We obtain some equations in terms of some suitable fractional derivatives and fractional difference operators, which provides the extension of known equations for the univariate processes. In particular we show that, for each fixed t≥0, the conditional joint distribution of the components given their sum is multinomial, as happens for the non fractional Poisson processes. Thus we consider a suitable multivariate "alternative" fractional Poisson process, and we study its asymptotic behavior for large times (large and moderate deviations). The results appear in two papers with Luisa Beghin Cordiali saluti, Barbara Martinucci

30 Sep '19

Da: "Centre de Recerca Matemàtica (CRM)" difusions(a)crm.cat Cc: Data: Mon, 30 Sep 2019 12:18:34 +0000 Oggetto: 🆕 Intensive Research Programme in Quantitative Finance View this email in your browser [1] Dear colleague, we are pleased to announce the forthcoming CRM Intensive Research Programme in QUANTITATIVE FINANCE JUNE – JULY 2020 Centre de Recerca Matemàtica (BARCELONA) This intensive program focuses in hot topics in Quantitative Finance. In the last decades, problems emerging in the financial industry have been a starting point for the development of quantitative techniques. These techniques cover a wide spectrum of mathematical fields, from probability theory to numerical and computational tools. A huge volume of research has done in the academia inspired by these problems. In the contrary direction, the financial industry is using more and more advanced (from the mathematical point of view) tools and concepts, due to the increasing complexity of markets, that can only be addressed with high-level quantitative methods. This program has been designed to create a bridge between the academia and the industry and it is thought to be a forum to gather professionals working in this area. This means, from the academia, the financial industry and specialized software companies. The program will last for two months and it will take place at the Centre de Recerca Matemàtica during the period June-July 2020. The program is composed of: ADVANCED COURSE ON NUMERICAL METHODS IN FINANCE [2]. June 8th to 12th, 2020 ADVANCED COURSE ON STOCHASTIC TOOLS IN FINANCE [3]. June 15th to 19th, 2020 WEEKLY SEMINARS FOR RESEARCHERS. June 22nd to July 24th, 2020 WEEKLY SEMINARS FOR STUDENTS. June 22nd to July 24th, 2020 WORKSHOP: NEW CHALLENGES IN QUANTITATIVE FINANCE [4].

Seminar Panaretos @Bocconi
by Giacomo Zanella 27 Sep '19

27 Sep '19

We announce the following DEC Statistics seminar: Thursday, October 3 12:30 Meeting room 3-e4-sr03, Bocconi University, Via Roentgen 1, 3rd floor Victor Panaretos (École Polytechnique Fédérale de Lausanne) Title: Fréchet Means and Procrustes Analysis in Wasserstein Space Abstract: Given a collection of diffuse random measures in R^d, we consider the problems of: constructing their optimal multicoupling in a mean square sense (a.k.a. Procrustes analysis); and of determining their Fréchet mean with respect to the Wasserstein metric. Though these problems admit explicit solutions when d=1, they are considerably more challenging when d>1. To attack them, we exploit the geometry of Wasserstein space, and specifically the relation between its tangent bundle and the class of optimal coupling maps. This allows us to determine the gradient of the Fréchet functional and show that the two problems at hand represent two sides of the same coin: gradient descent for the Fréchet mean reduces to a Procrustes algorithm, requiring only successive solution of pairwise coupling problems, thus being practically feasible; and the optimal maps obtained as a bye-product can be used to explicitly construct the optimal multi-coupling. We show how these results can be used in order to consistently solve the problem of registration of warped spatio-temporal point processes in an entirely nonparametric fashion, by means of appropriate regularisation. Kind regards, Giacomo Zanella The DEC statistics seminars schedule is available at http://www.unibocconi.eu/statseminar Please note: if you are a guest and you do not have a Bocconi ID Card to access to the Bocconi Buildings, please communicate your participation by sending an email to arianna.colombo(a)unibocconi.it

seminario Fabio Antonelli a Roma Tor Vergata
by Anna Vidotto 27 Sep '19

27 Sep '19

Dear all, I would like to announce the following talk that will be held on Friday, October 4th 2019, at 4:30 PM, in Aula Dal Passo of the Department of Mathematics, University of Rome Tor Vergata. Speaker: Fabio Antonelli Title: CVA and vulnerable options in stochastic volatility model Abstract: CVA adjustment in order to evaluate correctly derivatives subject to default risk has become more and more important in the past decade, especially when Wrong Way Risk, that is an increase in the product's price when deterioration of credit occurs. Considering the most common stochastic volatility models, we express WWR in terms of the correlation between asset's price and default event, that is described exploiting the so called intensity approach. When intensity follows an affine process, we are able to parametrize this correlation and, applying accurately Ito's formula, to suggest a Taylor polynomial approximation of CVA. Some numerical results showing the efficiency of the method are provided.

Seminario di Lorenzo Taggi a Roma 1
by Faggionato, Alessandra 24 Sep '19

24 Sep '19

Buongiorno il Dr. Lorenzo Taggi (WIAS - Berlino) terrà il seguente seminario Martedi' 1 Ottobre alle ore 14 in Aula di Consiglio del Dipartimento di Matematica alla Sapienza: *Title:* Absorbing-state phase transition in Activated Random Walk and Oil and Water. *Abstract:* We consider two interacting particle systems, Activated Random Walk and Oil and Water, which belong to the so-called class of Abelian networks. In these systems particles of two different types are present and the dynamics conserves the number of particles. This conservation law introduces hard-core constraints and long-range correlations which make the rigorous mathematical analysis particularly challenging. Activated Random Walk undergoes an absorbing-state phase transition, namely if the particle density is small enough, the activity dies out with time, while if the particle density is large enough, the activity is sustained. In recent years significant effort has been made to provide a rigorous proof of the occurrence of such a phase transition and a non-trivial characterisation of the critical particle density. Oil and Water shows a substantially different behaviour from Activated Random Walks and other Abelian networks: the activity dies out with time at *all *densities for *any *graph which is vertex-transitive. This talk reviews the main questions, results and conjectures about these models and presents joint works with E. Candellero and A. Stauffer. saluti alessandra ************************************************* Prof. Alessandra Faggionato http://www1.mat.uniroma1.it/~faggionato/ Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome Office 5, Phone (0039) 06 49913252 *************************************************

24 Sep '19

Si avvisa che il giorno martedì 1 ottobre alle ore 16 presso l’Università di Milano- Bicocca (via degli Arcimboldi 8 - edificio U7, quarto piano- aula 4026) si terrà il seguente seminario: Speaker: Samuel Cohen (University of Oxford) Titolo: “Learning and filtering in an uncertain setting” Abstract: Optimal filtering is a classical method for inferring the distribution of a hidden process from data. As an input it requires a probability model, which needs to be separately estimated. In this talk, we will look at what happens when we include the uncertainty of this estimation into our filtering problem, using a nonlinear expectation approach. A key difficulty is that one obtains a pathwise optimal control problem, which requires some care in analysis. We will see how we can ensure this problem remains well posed, and demonstrate the gains in performance from using this approach. Tutti gli interessati sono invitati a partecipare. Un saluto cordiale, Emanuela ******************************************************************************************* Emanuela Rosazza Gianin Dipartimento di Statistica e Metodi Quantitativi Università di Milano-Bicocca Edificio U7 – 4° Piano Via Bicocca degli Arcimboldi, 8 20126 Milano Tel. 02 64483208 e-mail: emanuela.rosazza1(a)unimib.it *******************************************************************************************

Carissimi, Vi ricordiamo che la settimana prossima si terrà la ottava giornata di seminari: A ``LATE-SUMMER'' DAY IN PROBABILITY AND STATISTICAL PHYSICS University of Florence Friday 27 September 2019 Lecturers: Pierre Picco (Marseille) and Rui Pires da Silva Castro (Eindhoven) Location: Aula Tricerri Viale Morgagni 67, Firenze Informazioni su come arrivare alla pagina: https://www.dimai.unifi.it/vp-285-come-arrivare-how-to-get.html <https://www.dimai.unifi.it/vp-285-come-arrivare-how-to-get.html> Note pratiche: Stiamo prenotando un catering con cibi vegerariani e non, percio` abbiamo bisogno del numero di persone che vogliono mangiare insieme. A coloro che fossero interessati (per una migliore organizzazione) chiediamo di mandare un email a francescaromana.nardi(a)unifi.it <mailto:francescaromana.nardi@unifi.it>; gianmarco.bet(a)unifi.it <mailto:gianmarco.bet@unifi.it>; angela.caporicci(a)unifi.it <mailto:angela.caporicci@unifi.it> con l'intenzione di partecipare al seminario, al coffe break e al pranzo. PROGRAMMA Prof. Pierre Picco (CNRS Marseille) Title: One-dimentional Ising model with long range interactions. A review of results Abstract: In the first talk I will make a quick historical survey of the rigorous results on the one-dimensional Ising model with long-range interactions. A first part will be dedicated to uniqueness of the Gibbs states (Ruelle (1968); Dobrushin (1968); Bricmont, Lebowitz & Pfister (1986)) and the regularity of the free energy when the decay of the potential is fast enough (Dobrushin (1973) Cassandro & Olivieri (1981) and its extensions in particular Capocaccia, Campanino & Olivieri (1983). A second part will be dedicated to the existence of phase transition starting from the Kac-Thompson conjecture (1968) the Dyson results (1969), the Frohlich \& Spencer result (1982), the Imbrie result (1982) the Aizenmann, Chayes, Chayes & Newman result on the Thouless effect (1988), Imbrie & Newman result on the Berezinsky, Kosterlitz & Thouless transition (1988). A third part will be dedicated to present results in the phase transition regime that started with Frohlich & Spencer (1981), Cassandro, Ferrari, Merola & Presutti (2001) and its extensions in particular by Cassandro, Merola, Picco & Rosikov (2014) on the definition of an interface and its fluctuations, and on a Minlos & Sinai theorem on the phase separation problem by Cassandro, Merola & Picco (2017). In the second talk I will review heuristic arguments that were invoked to conjecture the existence of a phase transition at low temperature in particular the Landau argument. I will present toy models where the fluctuation of interfaces and localisation of the droplet in the Minlos & Sinai theory will be explained. I will give an algorithmic definition of one-dimensional contours of Cassandro, Ferrari, Merola & Presutti. Prof. Rui Pires da Silva Castro (Eindhoven University of Technology) Title: Testing for the presence of communities in inhomogeneous random graphs Abstract: Many complex systems can be viewed as a network/graph consisting of vertices (e.g., individuals) connected by edges (e.g., a friendship relation). Often one believes there is some sort of community structure, where some vertices are naturally grouped together (e.g., more densely connected between themselves than to the rest of the network). Much of the community detection literature is concentrated around methods that extract communities from a given network. Our goal in this work is different, and we attempt to understand how difficult is it to determine if a network has real communities. Furthermore, we are primarily interested in the case of small or very small communities, for which many existing results and methods are not applicable. We cast this problem as a binary hypothesis test, where the null model corresponds to a graph without community structure, and the alternative model almost the same, but it also includes a planted community - that is, a small subset of the vertices has higher connection probability than under the null. The main question is to determine the minimal size and “strength” of the planted community that will allow detection. The seminal work of Arias-Castro and Verzelen tackled this problem when the null model is a homogeneous random graph. In our work, however, we consider the case where the null model is inhomogeneous, as this is somewhat closer to realistic scenarios. In particular, we present a scan test and provide conditions under which it is able to detect the presence of a small community. These results are valid for a wide variety of parameter choices. Furthermore, we show that for some parameters choices the scan test is optimal, and no other test can perform better (e.g, detect smaller or weaker planted communities). Finally, we extend this scan test to adapt to many parameters of the model when the null is a rank-1 generalized random graph. In the first part of the talk I will describe the above formulation and ensuing results, with illustrative examples and briefly touching upon the analytical methodology. In addition, I will discuss the related problem of characterizing cliques in rank-1 random graphs, which provides some insights on the role of inhomogeneity. The second part of the talk will go deeper into more technical aspects and ensuing insights. This presentation is based on joint work with Kay Bogerd and Remco van der Hofstad (https://arxiv.org/abs/1805.01688 <https://arxiv.org/abs/1805.01688> and ongoing work).

[Simai-soci] Fwd: Urgent: Open Letter to reinstate Research and Education as EC areas of focus
by c.costantini＠unich.it 20 Sep '19

20 Sep '19

Inolto questo messaggio della SIMAI. Un saluto, Cristina Costantini Cari Soci, ho ricevuto dalla presidente dell'ICIAM questo messaggio riguardante l'attuale composizione della Commissione Europea, dove non e` piu` presente un Commissario con un mandato specifico alla Ricerca, e alla Formazione, ma solo un generico "Commissioner for innovation and youth". Alcuni colleghi hanno preparato una lettera aperta per la Presidente della Commissione per sollecitare una migliore precisazione delle deleghe in "Education, Research, Innovation and Youth", per ribadire il ruolo fondamentale e specifico della formazione e ricerca. Se condividete la posizione firmate la petizione all'indirizzo indicato nel messaggio allegato (e fate circolare la lettera tra i colleghi). Un saluto, Luca ---------- Forwarded message --------- From: Maria J. ESTEBAN <esteban(a)ceremade.dauphine.fr> Date: Thu, Sep 19, 2019 at 2:05 PM Subject: Fwd: Urgent: Open Letter to reinstate Research and Education as EC areas of focus To: Wil Schilders <w.h.a.schilders(a)tue.nl>, Ari Laptev < laptev(a)mittag-leffler.se>, Helge Holden <secretary(a)mathunion.org>, Volker Mehrmann <Mehrmann(a)math.tu-berlin.de>, Alfio Quarteroni < alfio.quarteroni(a)epfl.ch>, luca formaggia <luca.formaggia(a)polimi.it>, Ball, John M <john.ball(a)hw.ac.uk> Dear friends, urgent action is required in the direction of Bruxelles, not only because there is no longer a commissioner for research (see below), but also because there is the looming threat of a substantial cut of the Horizon Europe Budget. If you resonate with what is written below could you please sign on the web site www.futureofresearch.eu and invite fellow scientists to do the same, i.e. widely distribute the email to all scientists? It is important to have also very visible people who sign, recipient of prizes or directors of big institutes, if you get them to sign, please signal to us so that it can be mentioned on the main webpage. It is urgent as the hearing is on 30.09.2019. At least 10000 signatures are needed in the next few days in order to be able to address the parliament.. thanks so much and all the best Maria ********************* Dear Colleague, We are writing you for the following reason: the candidates for the new EU commissioners were presented last week. In the new commission the areas of education and research are not explicitly represented anymore and instead are subsumed under the "innovation and youth" title. This emphasizes economic exploitability (i.e. "innovation") over its foundation, which is education and research, and it reduces “education” to “youth” while being essential to all ages. We, as members of the scientific community of Europe, wish to address this situation early on and emphasize both to the general public, as well as to relevant politicians on the national and European Union level, that without dedication to education and research there will neither exist a sound basis for innovation in Europe, nor can we fulfill the promise of a high standard of living for the citizens of Europe in a fierce global competition. President von der Leyen, in her mission letter to commissioner Gabriel (Web link to Mandate Letter: https://ec.europa.eu/commission/sites/beta-political/files/mission-letter-ma riya-gabriel-2019_en.pdf <https://ec.europa.eu/commission/sites/beta-political/files/mission-letter-m…>), has emphasized that “education, research and innovation will be key to our competitiveness”. We have prepared an open letter at www.futureofresearch.eu to demand that the EU commission revises the title for commissioner Gabriel to “Education, Research, Innovation and Youth” reflecting Europe’s dedication to all of these crucial areas. We also call upon the European Parliament to request this change in name before confirming the nominees for commissioner. Please support this letter by going to www.futureofresearch.eu and signing up as supporter on line.

Seminar Dunson @BIDSA, Bocconi
by Giacomo Zanella 16 Sep '19

16 Sep '19

We kindly invite you to the following BIDSA seminar: “Learning and exploiting low-dimensional structure in high-dimensional data” David Dunson (Duke University) September 19, 2019 | 12:30 | Room AS03 Bocconi University, Via Roentgen 1, underground floor Abstract: This talk will focus on the problem of learning low-dimensional geometric structure in high-dimensional data. We allow the lower-dimensional subspace to be non-linear. There are a variety of algorithms available for "manifold learning" and non-linear dimensionality reduction, mostly relying on locally linear approximations and not providing a likelihood-based approach for inferences. We propose a new class of simple geometric dictionaries for characterizing the subspace, along with a simple optimization algorithm and a model-based approach to inference. We provide strong theory support, in term of tight bounds on covering numbers, showing advantages of our approach relative to local linear dictionaries. These advantages are shown to carry over to practical performance in a variety of settings including manifold learning, manifold de-noising, data visualization (providing a competitor to the popular tSNE), classification (providing a competitor to deep neural networks that requires fewer training examples), and geodesic distance estimation. We additionally provide a Bayesian nonparametric methodology for inference, using a new class of kernels, which is shown to outperform current methods, such as mixtures of multivariate Gaussians. Speaker: David Dunson is Arts and Sciences Distinguished Professor of Statistical Science and Mathematics at Duke University. He is known for his broad spanning contributions to statistical methodology, with a particular focus on novel modeling frameworks and Bayesian approaches that are motivated by complex and high-dimensional data collected in the sciences. This includes latent factor, dimensionality reduction, nonparametric and machine learning methodology. Primary areas of application include neurosciences and brain network modeling, environmental health, ecology, and human fertility among others. He is a fellow of the ASA, IMS and ISBA and has won numerous awards, including most notably the 2010 COPSS President’s Award. His work is very widely cited and he has an H-index over 70 on Google Scholar. Best regards, Giacomo Zanella

Seminar Guindani @Bocconi
by Giacomo Zanella 06 Sep '19

06 Sep '19

We are glad to announce the first DEC Statistics Seminar of the Fall 2019 series: Thursday, September 12 12:30 Meeting room 3-e4-sr03, Bocconi University, Via Roentgen 1, 3rd floor Michele Guindani (University of California, Irvine) Title: Bayesian Approaches to Dynamic Model Selection Abstract: In many applications, investigators monitor processes that vary in space and time, with the goal of identifying temporally persistent and spatially localized departures from a baseline or ``normal" behavior. In this talk, I will first discuss a principled Bayesian approach for estimating time-varying functional connectivity networks from brain fMRI data. Dynamic functional connectivity, i.e., the study of how interactions among brain regions change dynamically over the course of an fMRI experiment, has recently received wide interest in the neuroimaging literature. Our method utilizes a hidden Markov model for classification of latent neurological states, achieving an estimation of the connectivity networks in an integrated framework that borrows strength over the entire time course of the experiment. Furthermore, we assume that the graph structures, which define the connectivity states at each time point, are related within a super-graph, to encourage the selection of the same edges among related graphs. Then, I will propose a Bayesian nonparametric model selection approach with an application to the monitoring of pneumonia and influenza (P&I) mortality, to detect influenza outbreaks in the continental United States. More specifically, we introduce a zero-inflated conditionally identically distributed species sampling prior which allows borrowing information across time and to assign data to clusters associated to either a null or an alternate process. Spatial dependences are accounted for by means of a Markov random field prior, which allows informing the selection based on inferences conducted at nearby locations. We show how the proposed modeling framework performs in an application to the P&I mortality data and in a simulation study and compare with common threshold methods for detecting outbreaks over time, with more recent Markov switching based models, and with other Bayesian nonparametric priors that do not take into account spatio-temporal dependence. Kind regards, Giacomo Zanella The DEC statistics seminars schedule is available at http://www.unibocconi.eu/statseminar Please note: if you are a guest and you do not have a Bocconi ID Card to access to the Bocconi Buildings, please communicate your participation by sending an email to arianna.colombo(a)unibocconi.it *************************************************** Giacomo Zanella Assistant Professor - Statistics DEC - Department of Decision Sciences Bocconi University

Just-in-time maintenance requires a very accurate, enhanced physically based data-driven assessment of the system’s health and its future evolution guaranteeing the reliability, availability and affordability of the system through accurate monitoring, prognostics and diagnostics. This is organized around the following key game changers: • *Development of a big data health index*. Intelligent systems are equipped with sensors collecting data real-time. Analyzing the collected data can guarantee the reliability, availability and affordability of the system through accurate monitoring, prognostics and diagnostics. However, when dealing with especially large and complex systems, a key challenge for engineers is how to assess the present condition. By measuring the dynamics of the asset/network, modelling the dynamic behavior and by combining the real-time information, we aim to assess the present condition in the form of a health index and predict the remaining useful life (based on an assumed usage profile) using big data analytic techniques stemming from machine learning and artificial intelligence. • *Causal discovery of failures and root cause analysis.* A key step in failure prevention is to understand why systems fail. Data-driven techniques are good at finding correlations between failure modes, but finding causal relations is challenging. Combinations with physical models and domain knowledge will create crucial actionable insight and condition assessment. These associations will be incorporated in a dynamic estimation and inference paradigm framework for extracting causal graph dynamics, which can be efficiently queried to find the root causes of specific failures. • *Model-enhanced big data techniques for decision making under uncertainty*. To cope with the complex reality, we need hybrid approaches leveraging the advantages of statistical methods (guaranteed performance and uncertainty bounds), data mining approaches (superior in situations where rules are not yet known), and physics of failure models (causality). We propose to combine big data analytic techniques stemming from machine learning and artificial intelligence with the more classical decision-making approaches (stochastic dynamic programming, Markov decision models). This combination goes in two directions: (i) on the one hand, we propose to use big data analytics to automatically learn the health index model and other relevant failure models with the objective of optimally fitting the decision objective instead of the classical data fitting objective. (ii) On the other hand, we propose to use decision-making approaches to improve the data analytic techniques, e.g., by incorporating an exploration vs exploitation approach in the maintenance decision making to cope with the uncertainty in the information. *Job description* The project is methodologically oriented. It is on the interface of statistical operations research and machine learning, and it is strongly inspired by industrial challenges. The PhD project will be conducted in an international team and in close collaboration with academic and industrial partners of PrimaVera. The main goal of the PhD project is to develop mathematical tools/models/algorithms for (some of) the above-mentioned key game changers, and thus get a deeper insight. The research will be concluded with a PhD thesis. A small teaching load is part of the job. *Job requirements *Preference will be given to candidates in any branch of applied mathematics and to candidates from a different background (e.g. engineering) but with strong mathematical foundation.

A coloro che fossero interessati (per una migliore organizzazione) chiedo di mandare un email a francescaromana.nardi(a)unifi.it <mailto:francescaromana.nardi@unifi.it> ; gianmarco.bet(a)unifi.it <mailto:gianmarco.bet@unifi.it> ; angela.caporicci(a)unifi.it <mailto:angela.caporicci@unifi.it> , con l'intenzione di partecipare al seminario, al coffe break e al pranzo. PROGRAMMA Prof. Pierre Picco (CNRS Marseille) Title: One-dimentional Ising model with long range interactions. A review of results Abstract: Introductory lecture In the first talk I will make an quick historical survey of the rigorous results on the one-dimensional Ising model with long-range interactions. A first part will be dedicated to uniqueness of the Gibbs states (Ruelle (1968); Dobrushin (1968); Bricmont, Lebowitz & Pfister (1986)) and the regularity of the free energy when the decay of the potential is fast enough (Dobrushin (1973) Cassandro & Olivieri (1981) and its extensions in particular Capocaccia, Campanino & Olivieri (1983). A second part will be dedicated to the existence of phase transition starting from the Kac-Thompson conjecture (1968) the Dyson results (1969), the Frohlich \& Spencer result (1982), the Imbrie result (1982) the Aizenmann, Chayes, Chayes & Newman result on the Thouless effect (1988), Imbrie & Newman result on the Berezinsky, Kosterlitz & Thouless transition (1988). A third part will be dedicated to present results in the phase transition regime that started with Frohlich & Spencer (1981), Cassandro, Ferrari, Merola & Presutti (2001) and its extensions in particular by Cassandro, Merola, Picco & Rosikov (2014) on the definition of an interface and its fluctuations, and on a Minlos & Sinai theorem on the phase separation problem by Cassandro, Merola & Picco (2017). Seminar In the second talk I will review heuristic arguments that were invoked to conjecture the existence of a phase transition at low temperature in particular the Landau argument. I will present toy models where the fluctuation of interfaces and localisation of the droplet in the Minlos & Sinai theory will be explained. I will give an algorithmic definition of one-dimensional contours of Cassandro, Ferrari, Merola & Presutti. Prof. Rui Pires da Silva Castro (Eindhoven University of Technology) Title: Testing for the presence of communities in inhomogeneous random graphs Abstract: Many complex systems can be viewed as a network/graph consisting of vertices (e.g., individuals) connected by edges (e.g., a friendship relation). Often one believes there is some sort of community structure, where some vertices are naturally grouped together (e.g., more densely connected between themselves than to the rest of the network). Much of the community detection literature is concentrated around methods that extract communities from a given network. Our goal in this work is different, and we attempt to understand how difficult is it to determine if a network has real communities. Furthermore, we are primarily interested in the case of small or very small communities, for which many existing results and methods are not applicable. We cast this problem as a binary hypothesis test, where the null model corresponds to a graph without community structure, and the alternative model almost the same, but it also includes a planted community - that is, a small subset of the vertices has higher connection probability than under the null. The main question is to determine the minimal size and “strength” of the planted community that will allow detection. The seminal work of Arias-Castro and Verzelen tackled this problem when the null model is a homogeneous random graph. In our work, however, we consider the case where the null model is inhomogeneous, as this is somewhat closer to realistic scenarios. In particular, we present a scan test and provide conditions under which it is able to detect the presence of a small community. These results are valid for a wide variety of parameter choices. Furthermore, we show that for some parameters choices the scan test is optimal, and no other test can perform better (e.g, detect smaller or weaker planted communities). Finally, we extend this scan test to adapt to many parameters of the model when the null is a rank-1 generalized random graph. In the first part of the talk I will describe the above formulation and ensuing results, with illustrative examples and briefly touching upon the analytical methodology. In addition, I will discuss the related problem of characterizing cliques in rank-1 random graphs, which provides some insights on the role of inhomogeneity. The second part of the talk will go deeper into more technical aspects and ensuing insights. This presentation is based on joint work with Kay Bogerd and Remco van der Hofstad (https://arxiv.org/abs/1805.01688 and ongoing work).
