Seminar by Katia Colaneri in Milan (25.01.23)
by Valeria Bignozzi 23 May '23

23 May '23

Dear all, you're invited to the seminar that will take place, in hybrid mode, at the Department of Statistics and Quantitative Methods, University of Milano-Bicocca. More details: • Speaker: Katia Colaneri (email: katia.colaneri(a)uniroma2.it <mailto:katia.colaneri@uniroma2.it>) Title: Some Optimisation Problems in Insurance with a Terminal Distribution Constraint Abstract: In this paper, we study two optimisation settings for an insurance company, under the constraint that the terminal surplus at a deterministic and finite time T follows a normal distribution with a given mean and a given variance. In both cases, the surplus of the insurance company is assumed to follow a Brownian motion with drift. First, we allow the insurance company to pay dividends and seek to maximise the expected discounted dividend payments or to minimise the ruin probability under the terminal distribution constraint. Here, we find explicit expressions for the optimal strategies in both cases, when the dividend strategy is updated at discrete points in time and continuously in time. Second, we let the insurance company buy a reinsurance contract for a pool of insured or a branch of business. We only allow for piecewise constant reinsurance strategies producing a normally distributed terminal surplus, whose mean and variance lead to a given Value at Risk or Expected Shortfall at some confidence level α. We investigate the question which admissible reinsurance strategy produces a smaller ruin probability, if the ruin-checks are due at discrete deterministic points in time. This presentation is based on a joint work with Julia Eisenberg (TU Vienna) and Benedetta Salterini (University of Firenze) Seminar venue: University of Milano-Bicocca Department of Statistics and Quantitative Methods Aula Seminari 4026, 4th floor, Building U7 January 25th, 4:30 pm Webex Link : https://unimib.webex.com/unimib/j.php?MTID=m40cd4bb0d7bb8035ca68f3821f453b33 <https://unimib.webex.com/unimib/j.php?MTID=m40cd4bb0d7bb8035ca68f3821f453b33> Join by meeting number Meeting number (access code): 2743 983 3965 Meeting password: c2uJfPBVe83 (22853728 from phones) Best regards, Valeria

Seminar: Giovanni Conforti at Tor Vergata
by mic sal 02 Feb '23

02 Feb '23

Dear all, On Wednesday, February 1st, at 14h00 in Aula Dal Passo at Roma Tor Vergata, RoMaDS (https://www.mat.uniroma2.it/~rds/about.php) will host Giovanni Conforti (École Polytechnique) with the seminar "A probabilistic approach to exponential convergence of Sinkhorn's algorithm" Abstract: The entropic optimal transport problem (EOT) is obtained adding an entropic regularisation term in the cost function of the Monge-Kantorovich problem and is nowadays regularly employed in machine learning applications as a more tractable and numerically more stable version of the optimal transport problem. On the other hand, E.Schrödinger asked back in 1931 the question of finding the most likely evolution of a cloud of independent Brownian particles conditionally to observations. The mathematical formulation of his question through large deviations theory is known as the Schrödinger problem and turns out to be fully equivalent to EOT. In this talk, I shall illustrate both viewpoints and then move on to sketch the ideas of a probabilistic method to show exponential convergence of Sinkhorn's algorithm, whose application the heart of the recent successful applications of EOT in statistical machine learning and beyond. In particular, we shall discuss how the proposed method opens new perspective for showing exponential convergence for marginal distribution that are non compactly supported. We encourage in-person partecipation.

30 Jan '23

Dear Colleagues, We would like to invite you to the following SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi: *Convergence rates and CLT for stochastic inviscid Leray-model with transport noise* *Dejun Luo* (Chinese Academy of Science) The seminar will take place on TUE, 31.1.2023 at 14:00 CET in Sala Seminari, Dipartimento di Matematica, Pisa and streamed online at the link below. The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass -------------------------------------------- *Abstract: * *The stochastic inviscid Leray- model perturbed by multiplicative transport noise is considered on the torus. Under a suitable scaling of the noise, it is shown that the weak solutions converge, in some negative Sobolev spaces, to the unique solution of the deterministic viscous Leray- model. Interpreting such limit result as a law of large numbers, we also study the underlying central limit theorem and provide an explicit convergence rate. This talk is based on a joint work with PhD Bin Tang.*

Seminario Prof. E. Ronchetti
by Enea Bongiorno 24 Jan '23

24 Jan '23

Buongiorno, con piacere segnalo il seguente seminario: -------------------------------- 31 gennaio ore 16.30 - aula 101, campus Perrone, via Perrone, 18, Novara. Università del Piemonte Orientale. - on-line: meet.google.com/yvq-ccbt-pzt Title: *An Introduction to Saddlepoint Approximations* *Prof. Elvezio Ronchetti* Research Center for Statistics and Geneva School of Economics and Management University of Geneva, Switzerland Elvezio.Ronchetti(a)unige.ch www.unige.ch/gsem/en/research/faculty/honorary-professors/elvezio-ronchetti/ Abstract: Classical inference in statistics is typically carried out by means of standard (first-order) asymptotic theory. However, the asymptotic distribution of estimators and test statistics can provide a poor approximation of tail areas especially when the sample size is moderate to small. This can lead to inaccurate p-values and confidence intervals. Several techniques, both parametric and nonparametric, have been devised to improve first-order asymptotic approximations, including e.g. Edgeworth expansions, Bartlett's corrections, and bootstrap methods. Here we focus on saddlepoint techniques, introduced into statistics by H. Daniels, and more generally on small sample asymptotic techniques, an expression coined by F. Hampel to express the spirit of these methods. Indeed they provide very accurate approximations of tail probabilities down to small sample sizes and /or out in the tails. Moreover, these approximations exhibit a relative error of order 1/n, an improvement with respect to other available approximations obtained by means of Edgeworth expansions and similar techniques. We will review the basic ideas, show the link with other nonparametric methods such as empirical likelihood, and outline some connections to information theory and optimal transportation. ----------------------------------- Locandina dell'evento <https://drive.google.com/file/d/1INut-6sD210FwZ437k3ydQA5P3xchdIr/view?usp=…> Seminari Matematici Statistici <https://sites.google.com/uniupo.it/seminari-ms/home-page> ----------------------------------- Tutti gli interessati sono invitati a partecipare.

23 Jan '23

We announce the following seminar (held only in person): 26/01/2023 at 12:00 Bocconi University, Via Roentgen 1, Milan Room 3-B3-sr01, floor 3 Speaker: Olga Klopp (ESSEC and CREST). Personal webapge: http://kloppolga.perso.math.cnrs.fr/ Title: Optimality of Variational Inference for Stochastic Block Model Abstract: Variational methods are extremely popular in the analysis of network data. Statistical guarantees obtained for these methods typically provide asymptotic normality for the problem of estimation of global model parameters under the stochastic block model. In the present work, we consider the case of networks with missing links that is important in application and show that the variational approximation to the maximum likelihood estimator converges at the minimax rate. This provides the first minimax optimal and tractable estimator for the problem of parameter estimation for the stochastic block model. We complement our results with numerical studies of simulated and real networks, which confirm the advantages of this estimator over current methods.

IEEE MetroLivEnv 2023 - Special Session PROBABILITY AND MATHEMATICAL STATISTICS FOR LIVING ENVIRONMENT AND METROLOGY
by Antonella Iuliano 20 Jan '23

20 Jan '23

Dear Colleagues, we would like to draw your attention to the upcoming 2023 IEEE INTERNATIONAL WORKSHOP ON METROLOGY FOR LIVING ENVIRONMENT that will be held at the Politecnico di Milano, (Italy), 29 - 31 May, 2023. The following Special Session is open to receive your submissions. PROBABILITY AND MATHEMATICAL STATISTICS FOR LIVING ENVIRONMENT AND METROLOGY The application of metrology related to living environment plays an important role in many applicative contexts to understand and identify sources of variability and to minimise their influence. There is a lack of probabilistic and machine learning approaches in this field; therefore this session aims at covering this aspect. Probability Theory and Statistics provide powerful tools for the development of new mathematical models to describe real life phenomena. One of the most significant advantages of the probabilistic modeling is that it gives a comprehensive understanding of the uncertainty associated with a measurement result. Therefore, the goal of this session is to gather recent advancements with promising future perspectives on the application of mathematical models, in areas such as health care and environmental, to improve the quality of life. Website: https://www.metrolivenv.org/special-session-4 *Important deadlines:* *Extended Abstract Submission Deadline* January 31, 2023 *Extended Abstract Acceptance Notification* March 15, 2023 *Final Paper Submission Deadline* April 15, 2023 *Conference Dates* May 29-31, 2023 For further information and updates please visit the conference website: https://www.metrolivenv.org/ We are looking forward to Welcome you in Milan! Do not hesitate to forward this message to anyone who could be interested. Thank you very much for your kind consideration, and apologies for multiple copies. We look forward to hearing from you.

Seminario Prof. Leonenko
by Enrica Pirozzi 19 Jan '23

19 Jan '23

**** AVVISO di SEMINARIO Prof. Nikolai Leonenko School of Mathematics, Cardiff University, UK TITOLO: Limit theorems for the first Minkowski functional of Gaussian spatiotemporal random fields with long-memory Abstract The paper [1] addresses the asymptotic analysis of sojourn functionals of spatiotemporal Gaussian random fields with long-range dependence (LRD) in time also known as long memory. Specifically, reduction theorems are derived for local functionals of nonlinear transformation of such fields, with Hermite rank m ? 1, under general covariance structures. These results are proven to hold, in particular, for a family of non?separable covariance structures belonging to Gneiting class. For m = 1, under some general condition on covariance structure of spatiotemporal random field with long memory in time, the properly normalized first Minkowski functional converge in distribution to the normal law. For m = 2, under separability of the spatiotemporal covariance function in space and time, the properly normalized Minkowski functional, involving the modulus of a Gaussian random field, converges in distribution to the Rosenblatt type limiting distribution for a suitable range of the long memory parameter.

by alessandra bianchi 18 Jan '23

18 Jan '23

Dear Colleagues, We would like to invite you to the following seminar that will take place on January 27 at 14.30. The seminar will be held in person and online via the Zoom platform. The organizers, Alessandra Bianchi, Giorgia Callegaro, Marco Formentin _____________________________________________________ *Speaker*: Athanasios Vasileiadis (Université Côte d'Azur) *Title*: Solving Stochastic Control and Mean Field Games using Deep Reinforcement Learning *Date and time*: January 27, 2023 at 14.30 *Place*: Room 2BC30 of the Department of Mathematics, University of Padova *Zoom link*: https://unipd.zoom.us/j/83527477275 (meeting ID: 835 2747 7275) available also on the webpage https://www.math.unipd.it/~bianchi/seminari/ *Abstract*: In recent years there have been big breakthroughs in applying machine learning for the solution of control problems primarily solving the curse of dimensionality. In this talk we will lay the foundations of Reinforcement Learning and apply it to stochastic control problems first and then Mean Field Games. On the theoretical side we will see some guarantees for the convergence of the approximations, as well as how to use noise to learn the Nash Equilibria of the MFG problem. On the practical side we will use Artificial Neural Networks to look for the optimal controls in feedback form and discuss results in higher dimensions. -- Alessandra Bianchi Dip. di Matematica Università di Padova Via Trieste, 63 - 35121 Padova, Italy phone: +39 049 827 14 06 fax: +39 049 827 14 28 e-mail: bianchi(a)math.unipd.it http://www.math.unipd.it/~bianchi/

(PMS)^2 talks: E. Luongo and F. Grotto [Jan 23]
by Maurizia Rossi 18 Jan '23

18 Jan '23

Dear colleagues, We are happy to announce the following *hybrid - that is, in person with online streaming - *talks: Speaker: *Eliseo Luongo* (SNS Pisa) *Title:* A stochastic particle approximation approach of the 2D Navier-Stokes equations with vorticity generation. (See Abstract below.) Speaker: *Francesco Grotto *(Univ. di Pisa) *Title:* Area Excursions and nodal Leray measures for Random Waves on hyperbolic space. (See Abstract below.) Date and Time: *Monday January 23, 14:30-16:30 (Rome time zone)* Place: *Aula 3014,* *Dip. di Matematica e Applicazioni, Univ. di Milano-Bicocca*, via R. Cozzi 55, Milano *Webex link:https://unimib.webex.com/unimib-it/j.php?MTID=m4a814f4cfe7e7a7ace5ef5e… <https://unimib.webex.com/unimib-it/j.php?MTID=m4a814f4cfe7e7a7ace5ef5e4d3f6…>* *Meeting number:* 2743 324 2093 *Password:*YPiMid9rP83 *-* *Abstract (Luongo)*: Particle approximation of 2D Navier-Stokes equations is a relevant problem in fluid dynamics with consequences also in its numerical analysis. The problem is essentially solved in the case of domains without boundary, but it remains mostly open in the case of no-slip boundary conditions, due to the difficulty of understanding and modeling generation of vorticity close to the boundary. The solution of this problem could have a deep impact in our understanding of turbulence. In this talk we present a stochastic particle approximation method which allows us to treat 2D Navier-Stokes equations in the case of prescribed vorticity generation. Our approach is almost completely functional analytic based. Moreover we obtain finer convergence results to the solution of the Navier-Stokes equations compared to propagation of chaos techniques. The talk is based on a joint work with F. Grotto and M. Maurelli. *Abstract (Grotto):* Focusing on the asymptotic behavior of a couple of relevant geometric functionals, we will discuss analogies and differences between random wave models on hyperbolic space and other geometric settings on which the related theory is by now well-established. Based on joint work with Giovanni Peccati. - These talks are part of the *(PMS)^2: Pavia-Milano Seminar series on Probability and Mathematical Statistics* organized jointly by the universities Milano-Bicocca, Pavia, Milano-Politecnico.

Seminar in Statistics - ANGELIKA ROHDE
by Pierpaolo De Blasi 16 Jan '23

16 Jan '23

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 20 Gennaio 2023, alle ore 12.00, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Speaker: *Angelika Rohde* (University of Freiburg) Title: *Estimating functionals under local differential privacy* Abstract: We study the problem of estimating a functional $\theta(\mathbb{P})$ of an unknown probability distribution $\mathbb{P} \in\mathcal{P}$ in which the original iid sample $X_1,\dots, X_n$ is kept private even from the statistician via an $\alpha$-local differential privacy constraint. Let $\omega_{TV}$ denote the modulus of continuity of the functional $\theta$ over $\mathcal{P}$ with respect to total variation distance. For a large class of loss functions $l$ and a fixed privacy level $\alpha$, we prove that the privatized minimax risk is equivalent to $l(\omega_{TV}(n^{-1/2}))$ to within constants, under regularity conditions that are satisfied, in particular, if $\theta$ is linear and $\mathcal{P}$ is convex. Our results complement the theory developed by Donoho and Liu (1991 Ann. Statist. 19 633–667) with the nowadays highly relevant case of privatized data. Somewhat surprisingly, the difficulty of the estimation problem in the private case is characterized by $\omega_{TV}$, whereas, it is characterized by the Hellinger modulus of continuity if the original data $X_1,\dots, X_n$ are available. We also find that for locally private estimation of linear functionals over a convex model a simple sample mean estimator, based on independently and binary privatized observations, always achieves the minimax rate. In particular, over the larger class of so-called sequentially interactive privacy mechanisms, a non-interactive procedure attains this rate. Next, we turn to one of the most studied non-linear functionals, the quadratic functional. Here, in contrast, we show that for estimating the integrated square of a density, sequentially interactive privacy mechanisms improve substantially over the best possible non-interactive procedure in terms of minimax rate of estimation. In particular, in the non-interactive scenario we identify an elbow in the minimax rate at $s=3/4$, whereas in the sequentially interactive scenario the elbow is at $s=1/2$. This is markedly different from both, the case of direct observations, where the elbow is well-known to be at $s=1/4$, as well as from the case where Laplace noise is added to the original data, where an elbow at $s=9/4$ is obtained. ------------------------------------------------ Sarà possibile seguire il seminario anche in streaming: Join Zoom Meeting <https://us02web.zoom.us/j/89240989650?pwd=eVZSTUVEWHM2SnhBWXpnL21VU3gvQT09> Il seminario è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats -- Pierpaolo De Blasi University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/>

Seminario Paolo Dai Pra
by Enrica Pirozzi 11 Jan '23

11 Jan '23

AVVISO di SEMINARIO Prof. Paolo Dai Pra Università di Verona TITOLO Polarization and Coherence in Mean Field Games Driven by Private and Social Utility Abstract We study a mean field game in continuous time over a finite horizon, T, where the state of each agent is binary and where players base their strategic decisions on two, possibly competing, factors: the willingness to align with the majority (conformism) and the aspiration of sticking with the own type (stubbornness). We also consider a quadratic cost related to the rate at which a change in the state happens: changing opinion may be a costly operation. Depending on the parameters of the model, the game may have more than one Nash equilibrium, even though the corresponding N- player game does not. Moreover, it exhibits a very rich phase diagram, where polarized/unpolarized, coherent/incoherent equilibria may coexist, except for T small, where the equilibrium is always unique. We fully describe such phase diagram in closed form and provide a detailed numerical analysis of the N-player counterpart of the mean field game. Joint work with Marco Tolotti (Venezia) and Elena Sartori (Padova).

Annuncio Seminario Sapienza // Martedì 10 Gennaio // Lorenzo Dello Schiavo
by Lorenzo Taggi 09 Jan '23

09 Jan '23

Martedì 10 Gennaio 2023, ore 14:00 Sala di Consiglio, Dipartimento di Matematica, Sapienza Università di Roma *Speaker: *Lorenzo Dello Schiavo (ISTA, Vienna) *Titolo:* Scaling Limits of Random Walks, Harmonic Profiles, and Stationary Non-Equilibrium States in Lipschitz Domains *Abstract:* We consider the open symmetric exclusion (SEP) and inclusion (SIP) processes on a bounded Lipschitz domain Ω, with both fast and slow boundary. For the random walks on Ω dual to SEP/SIP we establish a functional-CLT-type convergence to the Brownian motion on Ω with either Neumann (slow boundary), Dirichlet (fast boundary), or Robin (at criticality) boundary conditions. We further show the discrete-to-continuum convergence of the corresponding harmonic profiles. As a consequence, we rigorously derive the hydrodynamic and hydrostatic limits for SEP/SIP on Ω, and analyze their stationary non-equilibrium fluctuations.

seminar on January 11, 2023 - Giulia Di Nunno - Reminder
by Emanuela Rosazza Gianin 07 Jan '23

07 Jan '23

Dear all, you are all invited to participate to the following seminar on *Wednesday 11th of January 2023 at 16:30* in Aula Seminari 4026 at University of Milano Bicocca (via degli Arcimboldi 8, Milano - building U7, 4th floor): Speaker: *Giulia Di Nunno* (University of Oslo) Titolo: *Sandwiched Volterra volatility models and hedging* Abstract: We present the Sandwiched Volterra Volatility (SVV) model and we discuss some of its characteristic properties. We then move to consider hedging and consider the explicit computation of quadratic hedging strategies. While the theoretical solution is well-known in terms of the non-anticipating derivative for all square integrable claims, the fact that these models are typically non-Markovian provides a concrete difficulty in the direct computation of conditional expectations at the core of the explicit hedging strategy. To overcome this difficulty, we propose a Markovian approximation of the model which stems from an adequate approximation of the kernel in the Volterra noise. We show some numerical simulations performed with different methods. Best wishes, Emanuela ****************************************** Emanuela Rosazza Gianin Department of Statistics and quantitative methods University of Milano-Bicocca Via Bicocca degli Arcimboldi, 8 20126 Milano - Italy Phone (0039) 02 64483208 e-mail: emanuela.rosazza1(a)unimib.it ******************************************

SPASS Seminar: Antonio Agresti - TUE 10.01 at 14:00
by Andrea Agazzi 04 Jan '23

04 Jan '23

Dear Colleagues, We would like to invite you to the following SPASS <https://sites.google.com/unipi.it/spass> seminar, jointly organized by UniPi, SNS, UniFi and UniSi: *The primitive equations with transport noise* by Antonio Agresti (ISTA - Institute of Science and Technology Austria) The seminar will take place in person on *TUE, 10.01.2023 at 14:00 CET* in Aula Seminari, Department of Mathematics, University of Pisa and streamed online here <https://meet.google.com/gji-phwo-vbg>. The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass -------------------------------------------- *Title: **The primitive equations with transport noise* *Abstract: **The primitive equations are one of the fundamental models for geophysical flows used to describe oceanic and atmospheric dynamics. In this talk I will discuss some recent results on the primitive equations with noise of transport type. In addition to transport noise, we also consider non-isothermal turbulent pressure. The dependence of the turbulent pressure on the temperature is a consequence of a stochastic Boussinesq approximation. For the primitive equations with transport noise and non-isothermal turbulent pressure, we provide a physical derivation and we discuss the global well-posedness for data in the critical spaces $H^1$. The latter result gives a non-trivial extension of the celebrated work by C. Cao and E.S. Titi on the deterministic model. Our approach is based on recent developments of maximal regularity techniques in the context of stochastic parabolic PDEs. If time allows, then I will also discuss further results in presence of rough noise.* *Based on joint works with M. Hieber (TU Darmstadt), A. Hussein (TU Kaiserslautern) and M. Saal (TU Darmstadt).*
