by Guillaume Kon Kam King 29 Nov '18

29 Nov '18

Dear all, Benoit Liquet (https://sites.google.com/site/benoitliquet/home) is advertising a postdoc position in Statistics, located in the South-West of France, near Biarritz. More details below, and in attachment. Please forward if you know any interested candidate. Best, Guillaume KON KAM KING Università degli Studi di Torino *https://sites.google.com/site/guillaumekonkamking/home <https://sites.google.com/site/guillaumekonkamking/home>* Recruitment grade: young researcher (i.e. with PhD) Location: Anglet, France Duration: 12 to 24 months, starting late 2018 (December or January 2019) Deadline: position open until filled Gross Salary Range: 2699 euros / month Postdoc description: Recently, several approaches were developed for completing the agnostic > genome-wide association studies (GWAS) in the discovery of new genetic risk > factors. One such approach is gene set analysis (GSA) that incorporates the > available biological knowledge of genes in order to provide additional > insights into the mechanisms involved in carcinogenesis. Another approach > proposed to test variants for association for multiple phenotypes as over > the years multiple loci have been found to be associated to several > distinct traits revealing the existence of pleiotropic effects. Although a > number of statistical approaches have been proposed in the literature for > identifying the existence of pleiotropy at SNP-level, not a lot of work has > been conducted for investigating pleiotropy at gene- and pathway-levels. We > aim to fill this gap by developing advanced statistical methods that test > for pleiotropic effects at a pathway level. Also, we will extend these > methods for the analysis of GxE interactions, as to the best of our > knowledge, pleiotropy methods have not adapted for testing for GxE > interactions. Therefore, our first objective is to develop novel > statistical methods that will identify shared pathways between different > diseases. Our second aim is to extend these methods for testing GxE in > general or in the context of pleiotropy. These methods will be applied to > explore the genetic relationship between differentiated thyroid cancer > (DTC) and breast cancer (BC) types. It has been shown that these two > cancers are linked as women with a prior history of DTC are at an increased > risk for BC and conversely.

We will use data from the CECILE study (1019 BC cases and 999 > controls) and from EPITHYR (1345 DTC cases and 1399 controls). All subjects > were genotyped using the OncoArray chip that includes more than 500 000 > variants. Through the developments of novel statistical methods, we aim to > elucidate the common mechanisms between BC and DTC. This project will lead > to the development of new statistical methods that will benefit both the > epidemiology and statistical communities. These methods will permit to gain > novel insights into the inherited genetic basis of BC and DTC by > identifying the common biological elements that contribute to their > aetiology.

seminario Felix Liebrich - 22 novembre - REMINDER
by Emanuela Rosazza 20 Nov '18

20 Nov '18

Si avvisa che il giorno giovedì 22 novembre alle ore 14 presso l’Università di Milano- Bicocca (via degli Arcimboldi 8 - edificio U7, quarto piano- aula 4026) si terrà il seguente seminario: Speaker: Felix-Benedikt Liebrich (LMU Muenchen, Germany) Titolo: “Sharing utility and risk under (partial) law-invariance” Abstract: The so-called risk sharing problem has two variants: (1) How can an aggregation of individual utilities within a system of agents be maximised by means of distributing a certain good, or (2) how can an aggregation of individual risks be minimised by means of redistributing a certain loss the system incurs? The problem has a long history in economics and financial mathematics, and solving it in relevant infinite dimensional spaces is very challenging. Substantial results have been obtained in the context of Pareto efficiency of such sharing schemes when law-invariant (risk) preferences are involved. These rank Savage acts -- random variables -- in a way which only depends on their distribution under a fixed reference probability measure. It was shown that Pareto efficient allocations (i.e. sharing schemes) exist. For problem (1) of maximising aggregated utility, the talk presents a unifying framework in which solutions to the risk sharing problem can be found. As applications, we will discuss the existence of weakly Pareto efficient allocations, Pareto efficient allocations, and core allocations. In a second part, we solve the risk sharing problem (2) for a wide class of capital requirements determining individual risks. These will not be law-invariant functionals, but build on a law-invariant ingredient. The talk is based on joint work with Gregor Svindland. 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 Fax. 02 64483105 e-mail: emanuela.rosazza1(a)unimib.it *******************************************************************************************

A Summer Day in Probability and Statistical Physics
by Francesca Romana Nardi 17 Nov '18

Carissimi, la prossima giornata di seminari sara` il 14 Settembre 2018. Ricordo che ciascuno oratore fara` una lezione introduttiva e divulgativa di 45 minuti pensata proprio per i non esperti, seguita da altri 45 minuti di tipo seminario (vedi programma). Maggiori informazioni e aggiornamenti sulle giornate passate e future sono reperibili alla pagina web che vi invitiamo a visitare periodicamente. http://web.math.unifi.it/users/fnardi/seminari/ A SUMMER DAY IN PROBABILITY AND STATISTICAL PHYSICS University of Florence Friday 14 September 2018 Lecturers: Stefano Olla (Paris) and Raúl Rechtman (Mexico) Location: Aula Magna di Via S. Gallo 10, Firenze Prof. Stefano Olla (Universite` Paris Dauphine) Title: Hyperbolic Hydrodynamic Limits Abstract: I will present a review of old and new results (and open problems) concerning scaling limits for conservation laws in the hyperbolic space-time scale, for a system of anharmonic oscillators with external boundary tension. The macroscopic equation is given by the compressible Euler system, with corresponding boundary conditions. The problem is particularly challenging when shockwaves are present. Some results exists when the microscopic dynamics is perturbed by a conservative stochastic viscosity. Works in Collaboration with Stefano Marchesani (GSSI) and Lu Xu (CEREMADE). Prof. Raúl Rechtman, (Universidad Nacional Autónoma de México) Title: Chaos and damage spreading in a probabilistic cellular automaton Abstract: Deterministic Boolean cellular automata (CA) are discrete maps F:BN → BN, B={0,1}, x(t+1)=F(x(t)) with x ϵ BN, N large and t=0,1,… . The vector x is the state of the cellular automaton with components xi,, i=0,…,N-1 the state of cell I. Each cell is connected to others, generally in a uniform and local way, and one can define an adjacency matrix aij=1 is cell j is connected to cell i and zero otherwise. The global map F is determined by the parallel application of a local function f, such that xi(t+1) = f(vi(t)), where vi denotes the state of cells connected to cell i. Deterministic CA are thus the discrete equivalent of dynamical systems, and many concepts like trajectory (the sequence of configurations x(t)), fixed points and limit cycles can be used. There are cellular automata for which a small modification in an initial configuration propagates to the whole system, a situation similar to chaos in continuous systems, and indeed one can extend the concept of the largest Lyapunov exponent to deterministic CA using Boolean derivatives. One of the main inconvenient is that these systems do not have continuous parameters to be tuned, in order to study bifurcations. In probabilistic cellular automata, the function f (and thus F) is defined in terms of transition probabilities so that deterministic CA can be seen as the extreme cases of probabilistic ones, when the transition probabilities are either zero or one. Probabilistic CA can be seen also as Markov chains, and one can observe interesting phase transitions after changing the transition probabilities that are therefore continuous control parameters. A realization of a specific trajectory is determined by the extraction of one or more of random numbers for each cell. By extracting these numbers at the beginning of the simulation, for all cells and all times, one converts a probabilistic CA into a deterministic one, running over a quenched random field. One can therefore use the concepts of deterministic CA, like damage spreading and maximum Lyapunov exponent also for probabilistic CA, with the advantage of having the possibility of fine-tuning the control parameters. In particular, we investigate a probabilistic cellular automaton which can be considered an extension of a model in the universality class of directed percolation models, but with two absorbing states. In the first part of the talk all the concepts mentioned above are defined and in the second part, the probabilistic cellular automaton is studied numerically. We show that the phase transitions when the order parameter is the average damage do not coincide with those found for the Lyapunov exponent and the reason of this is the presence of absorbing states.

STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO Venerdì 23 Novembre 2018, alle ore 12:00, presso il nuovo edificio del Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Eleni MATECHOU (University of Kent) BAYESIAN NONPARAMETRIC MODELLING OF PHENOLOGY USING CAPTURE-RECAPTURE DATA. Phenological shifts, that is changes in the timing of cyclic and seasonal phenomena, have been observed for a number of wildlife species in recent years. These shifts are often attributed to the warming climate and their effect on population sizes is a matter of great concern. In this talk, I show how Bayesian nonparametrics can be employed when modelling capture-recapture data to obtain smooth and ecologically meaningful estimates of arrival and departure densities at one or more sites and as functions of environmental covariates or to account for individual phenological heterogeneity. ------------------------------------------------ Tutti gli interessati sono invitati a partecipare.

de Finetti risk seminar - November 2018
by Emanuela Rosazza 15 Nov '18

15 Nov '18

On behalf of the Scientific Committee of the de Finetti Risk Seminars, we are glad to invite you to participate at the following Lecture Mathias Beiglboeck University of Vienna Title: Adapted transport and mathematical finance Abstract: Adapted transport plans generalize adapted processes in the same way as usual transport plans are a relaxed form of Monge-mappings. Correspondingly, one obtains an adapted / causal variant of the usual Wasserstein distance. We will review these concepts and explain why they are relevant for mathematical finance and in particular the problems involving model-uncertainty. LOCATION: The seminar will be held on Wednesday, November 21, at 18.00, Aula di rappresentanza, Dept. of Mathematics, Milano University, Via C. Saldini 50, Milano.

Politecnico di Milano - Seminario Fiserova

10 Nov '18

Si avvisa che in data 21-11-2018, alle ore 14:30 precise, presso l'Aula Seminari "F. Saleri" VI piano, Dipartimento di Matematica, Politecnico di Milano, si svolgerà il seguente seminario: Relatore Eva Fiserova, Palacky University Olomouc, Czech Republic Titolo Working with compositional data in coordinates Abstract Compositional data are multivariate observations carrying only relative information, popularly expressed in percentages, proportions, mg/kg, etc. Because of features inherent to compositional data, such as scale invariance and the relative scale, the statistical analysis of raw compositional data often leads to spurious results. Natural principles of compositional data are followed by the Aitchison geometry on a simplex, the sample space of compositional data (Aitchison, 1986; Pawlowsky-Glahn et al., 2015). However, because most standard statistical methods rely on the Euclidean geometry in real space, compositional data need to be converted to this space prior to statistical processing. In the lecture, we will present the log ratio methodology for dealing with compositional data and several types of their coordinate representations, such as orthonormal log-ratio coordinates, pivot coordinates, weighted pivot coordinates (Hron et al., 2017), or symmetric balances (Kynvclova et al., 2017). Their usage will be demonstrated on examples. Tutti gli interessati sono invitati a partecipare.

Department of Economics and Finance LUISS Viale Romania 32 00196 Roma November 15, 2018, 12:00 noon Room 207 *Speaker: *Mathias Staudigl / Maastricht University *Title: * *“Learning in Time Varying Games”* *Abstract:* *“In this paper, we examine the long-term behavior of regret minimizing agents in time-varying games with continuous action spaces. In its most basic form, (external) regret minimization guarantees that an agent’s cumulative payoff is no worse in the long run than that of the agent’s best fixed action in hindsight. Going beyond this worst-case guarantee, we consider a dynamic regret variant that compares the agent’s accrued rewards to those of any sequence of play. Specializing to a wide class of no-regret strategies based on mirror descent, we derive explicit rates of regret minimization relying only on imperfect gradient observations. We then leverage these results to show that players are able to stay close to Nash equilibrium in time-varying monotone games – and even converge to Nash equilibrium if the sequence of stage games admits a limit.”* The calendar of the future seminars can be found at http://economiaefinanza.luiss.it/en/seminari/prossimi-seminari ******************************************************* Marco Scarsini Dipartimento di Economia e Finanza LUISS Viale Romania 32 00197 Roma, ITALY URL: http://docenti.luiss.it/scarsini/

seminario 13 novembre 9, 30 al Politecnico di Torino DISMA
by Enrico Bibbona 06 Nov '18

06 Nov '18

Martedi' 13 novembre alle 9,30 in Aula Buzano (Politecnico di Torino, DISMA) il prof Badal Joshi (California State University San Marcos) terrà un seminario dal titolo Graphical symmetries of reaction networks and their stationary measures Abstract: Reaction networks are used to model chemical reactions, biochemical reactions, interacting populations in ecology, genetics and infectious disease dynamics among many other systems. Depending on the system scale, three most commonly used models are continuous-time Markov chain (CTMC), stochastic differential equations and ordinary differential equations (ODE). With increased data and scientific focus shifting towards biochemistry which often involves populations as small as few tens of molecules, CTMC models have seen dramatic increase in relevance. The long-term dynamics of a continuous-time Markov chain model are described by its stationary distribution. In general, the explicit form of the stationary distribution is impossible to obtain even for very small networks. However, when the network has some natural symmetries, we can obtain the explicit stationary distribution and it can be connected with the equilibria of the corresponding ODE system. We will discuss the symmetries of reaction balance, complex balance, reaction vector balance, and cycle balance and their properties in both the deterministic (ODE) setting and stochastic (CTMC) setting. We will also discuss the relations between the various forms of balance and the connection with existence and form of the stationary distribution.

seminario Felix Liebrich - 22 novembre

06 Nov '18

Si avvisa che il giorno giovedì 22 novembre alle ore 14 presso l’Università di Milano- Bicocca (via degli Arcimboldi 8 - edificio U7, quarto piano- aula 4026) si terrà il seguente seminario: Speaker: Felix-Benedikt Liebrich (LMU Muenchen, Germany) Titolo: “Sharing utility and risk under (partial) law-invariance” Abstract: The so-called risk sharing problem has two variants: (1) How can an aggregation of individual utilities within a system of agents be maximised by means of distributing a certain good, or (2) how can an aggregation of individual risks be minimised by means of redistributing a certain loss the system incurs? The problem has a long history in economics and financial mathematics, and solving it in relevant infinite dimensional spaces is very challenging. Substantial results have been obtained in the context of Pareto efficiency of such sharing schemes when law-invariant (risk) preferences are involved. These rank Savage acts -- random variables -- in a way which only depends on their distribution under a fixed reference probability measure. It was shown that Pareto efficient allocations (i.e. sharing schemes) exist. For problem (1) of maximising aggregated utility, the talk presents a unifying framework in which solutions to the risk sharing problem can be found. As applications, we will discuss the existence of weakly Pareto efficient allocations, Pareto efficient allocations, and core allocations. In a second part, we solve the risk sharing problem (2) for a wide class of capital requirements determining individual risks. These will not be law-invariant functionals, but build on a law-invariant ingredient. The talk is based on joint work with Gregor Svindland. Tutti gli interessati sono invitati a partecipare.

We develop a method to study the implied volatility for exotic options and volatility derivatives with European payoffs such as VIX options. Our approach, based on Malliavin calculus techniques, allows us to describe the properties of the at-the-money implied volatility (ATMI) in terms of the Malliavin derivatives of the underlying process. More precisely, we study the short-time behaviour of the ATMI level and skew. As an application, we describe the short-term behavior of the ATMI of VIX and realized variance options in terms of the Hurst parameter of the model, and most importantly we describe the class of volatility processes that generate a positive skew for the VIX implied volatility. In addition, we find that our ATMI asymptotic formulae perform very well even for large maturities. Several numerical examples are provided to support our theoretical results. -- Dott.

Torino - Lezione Lagrangiana M. Hairer - 13 Novembre

Annuncio Lezione Lagrangiana al Dipartimento di Matematica "G. Peano", Universita` di Torino Martedì 13 novembre alle ore 16.30 in Aula A Martin Hairer (Imperial College, London) "Taming Infinities" Abstract: Some physical and mathematical theories have the unfortunate feature that if one takes them at face value, many quantities of interest appear to be infinite! What's worse, this doesn't just happen for some exotic theories, but in the standard theories describing some of the most fundamental aspects of nature. Various techniques, usually going under the common name of “renormalisation” have been developed over the years to address this, allowing mathematicians and physicists to tame these infinities. We will tip our toes into some of the conceptual and mathematical aspects of these techniques and we will see how they have recently been used to study equations whose meaning was not even clear until now.

The Aldous spectral gap phenomenon: seminario di Filippo Cesi il 14-11-2018 a Roma Tre
by Pietro Caputo 31 Oct '18

31 Oct '18

Prof. Filippo Cesi Universita' La Sapienza Roma Titolo: THE ALDOUS' SPECTRAL GAP PHENOMENON Mercoledi' 14 Novembre 2018 ORE 16:00 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre Largo San Leonardo Murialdo, 1 - Pal.C - Aula 211 Abstract: Some families of Markov chains have a spectral gap which coincides with the spectral gap of an extremely simplified version of the chain. Another way of restating the same concept is: some families of Cayley graphs have a spectral gap which can be found in a very low dimensional representation of the underlying group. We will present a general approach which could be useful when going fishing for this phenomenon in an arbitrary finite group. Two specific examples will be discussed: the case of the symmetric group which corresponds to the "original" Aldous' spectral gap conjecture, proven in 2010 by Caputo, Liggett and Richthammer, and case of the Weyl group W(B_n) we studied in a recent paper.

We are investigating the following problems rigorously: 1. Find a best possible embedding of an Ising model on a irregular graph to an Ising model on a given regular graph. 2. Find the ground state of the above Ising model on the regular graph by a sampler faster than, say, Glauber dynamics. 3. Find how stable the ground state is against noise in coupling coefficients and/or external magnetic fields. 4. Find killer applications of the Ising computer. The posdoc position is a 2-year position, starting from April 2019 the earliest, with possible 2-year extension (depending on performance). The net salary will be ranging from 3,769,524 JPY to 5,689,524 JPY (depending on previous experiences). The deadline of application (send via email a CV and a list of publications to: sakai(a)math.sci.hokudai.ac.jp) is set on December 15, 2018.

Seminario a Bologna del prof. Macci
by Massimo Campanino 29 Oct '18

29 Oct '18

Il giorno mercoledì 7 novembre alle ore 17 nell'aula al VII piano del Dipartimento di Matematica dell'Università di Bologna in piazza Porta S. Donato 5 il prof. Claudio Macci del Dipartimento di Matematica dell'Università di Roma Tor Vergata terrà un seminario dal titolo Asymptotic behavior of some hitting probabilities for sums of IID Gaussian random sets Abstract: We consider sequences of partial sums of iid Gaussian random sets (with respect to the Minkowski sum) and we study t he asymptotic behavior of some hitting probabilities (of suitable sets of $R^d$) for these partial sums. We also illustrate the use of the importance sampling for the estimation of these hitting probabilities by Monte Carlo simulations. We obtain the analog of well-known results for level crossing probabilities of random walks, and we refer to a version of the classical Cramér's Theorem in large deviations for random compact sets existing in the literature.

Seminario tra Geometria e Probabilita' di Daniele Agostini a Roma Tre il 29-10-2018

Daniele Agostini (Max-Plank Institute fur Mathematik, Leipzig) Titolo: Discrete Gaussians, theta functions and abelian varieties Lunedi' 29 Ottobre 2018 ORE 14:30 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre Largo San Leonardo Murialdo,1 - Pal.C - Aula 009 Abstract The Gaussian distribution is a central object in mathematics and it can be characterised as the unique probability on the real numbers that maximises entropy, for fixed mean and variance. It turns out that the same property can be used to define a discrete Gaussian distribution on the integers. Moreover, the discrete Gaussian is parametrised naturally by the Riemann theta function, and, as such, it has a natural connection to the theory of abelian varieties in algebraic geometry. The aim of the talk is to present this connection and to show how question in probability give rise to natural problems in algebraic geometry and viceversa. This is joint work with Carlos Amendola (TU Munich).

Il giorno giovedì 15 novembre alle ore 16 nell'aula Seminario 2 del Dipartimento di Matematica dell'Università di Bologna (pazza Porta S. Donato 2) il dott. Gianluca Bosi dell'Università di Bologna terrà un seminario dal titolo Revolving random walks in 2D: analysis of type and winding number. We consider simple random walks on two directed versions of the $\mathbb{Z}^2$ lattice; one characteristic feature of these random walks is that they are bound to revolve, according to the orientation prescribed by the edges. The first model was studied by Campanino and Petritis(‘03) and shown to be transient; the other one appeared recently in a paper by Menshikov et al. (’17), where the authors conjectured its recurrence. We shall indeed confirm this conjecture: our proof is done by considering a continuous analogue of the random walk and then applying the Lyapunov function criteria. On the other hand, we obtain a local limit theorem for the return probabilities of the first random walk, which in particular gives a new proof of transience. Finally, we deduce some results related to the winding number for both random walks. This results are joint work with Y.Peres (Microsoft Research, Redmond) and Y.Hu (University of Washington).

Seminario BELITSER

22 Oct '18

STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO Venerdì 26 Ottobre 2018, alle ore 12:00, presso il nuovo edificio del Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Eduard BELITSER (Vrije Universiteit Amsterdam) ROBUST INFERENCE FOR GENERAL PROJECTION STRUCTURES BY EMPIRICAL BAYES AND PENALIZATION METHODS We develop a general framework of projection structures and study the problem of inference on the unknown parameter within this framework by using empirical Bayes and penalization methods. The main inference problem is the uncertainty quantification, but on the way we solve the estimation and posterior contraction problems as well (also a weak version of structure recovery problem). The approach is local in that the quality of the inference procedures is measured by the local quantity, the oracle rate, which is the best trade-off between the approximation error by a projection structure and the complexity of that approximating projection structure. The approach is also robust in that the stochastic part of the general framework is assumed to satisfy only certain mild condition, the errors may be non-iid with unknown distribution. We introduce the excessive bias restriction (EBR) under which we establish the local (oracle) confidence optimality of the constructed confidence ball. As the proposed general framework unifies a very broad class of high-dimensional models interesting and important on their own right, the obtained general results deliver a whole avenue of results (many new ones and some known in the literature) for particular models and structures as consequences, including white noise model and density estimation with smoothness structure, linear regression and dictionary learning with sparsity structures, biclustering and stochastic block models with clustering structure, covariance matrix estimation with banding and sparsity structures, and many others. Many adaptive minimax results over various scales follow from our local results. (Joint work with N. Nurushev.) ------------------------------------------------ Tutti gli interessati sono invitati a partecipare. Il seminario è organizzato dalla "de Castro" Statistics Initiative (www.carloalberto.org/stats) in collaborazione con il Collegio Carlo Alberto. Cordiali saluti, Matteo Ruggiero --- Matteo Ruggiero University of Torino and Collegio Carlo Alberto www.matteoruggiero.it
