Carissimi, vi ricordo il seminario di venerdi` prossimo 25 Maggio (vedi annuncio sotto per dettagli). Stiamo prenotando un ristorante diverso dal precedente con cucina fiorentina e prezzo contenuto, per questo ho bisogno del numero ESATTO di persone. Potreste farmi sapere chi intende mangiare con il gruppo per favore? A prestissimo Francesca R Nardi -------- Messaggio originale -------- OGGETTO: A Spring Day in Probability and Statistical Physics DATA: Venerdì 27/04/2018 18:13 MITTENTE: Francesca Romana Nardi <francescaromana.nardi(a)unifi.it> DESTINATARIO: random(a)fields.dm.unipi.it Carissimi, stiamo preparando la prossima giornata di seminari del 25 Maggio 2018 (quarto incontro della serie di giornate sulla probabilita` e le sue applicazioni alla Fisica, Biologia e Scienze sociali). 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). Per maggiori informazioni e aggiornamenti sulle giornate passate e future abbiamo istituito una pagina web che vi invitiamo a visitare periodicamente. http://web.math.unifi.it/users/fnardi/seminari/ A SPRING DAY IN PROBABILITY AND STATISTICAL PHYSICS University of Florence Friday 25 May 2018 Lecturers: Francis Comets (Paris) and Remco van der Hofstad (Eindhoven) Location: Aula Magna di Via S. Gallo 10, Firenze Prof. Francis Comets (University of Paris Diderot) Title: Cover time, cover process, random interlacements for random walk on the torus, I and II" Abstract: The cover time is the time needed for the $d$-dimensional simple random walk to visit all points of the torus of size $n$ on the lattice $Z^d$; in the continuum, it is the time for the Wiener sausage of radius 1 to cover the torus of linear size $n$. As a maximum of correlated random variables (here, with logarithmic decay when $d=2$) it has interesting asymptotics as $n \to \infty$, which are related to the way the covering is performed. Things are different in dimension $d \geq 3$ (the walk is transient) from dimension $d=1,2$ (the walk is recurrent). In dimension $d \geq 3$, Sznitman introduced random interlacements to describe the local picture during the covering process. They consist in a Poissonian soup of bi-inifinite random walk trajectories. They still give a reliable account at large densities, up to cover time. We will emphasize dimension 2: random interlacements can be used as a description of the neighborhood of an unvisited site, provided that the paths used in the interlacements are random walk _conditioned not to visit a point_. (Joint works with Serguei Popov and Marina Vachkovskaia.) (Leiden University) Prof. Remco van der Hofstad (Technical University Eindhoven) Title: Ising models on random graphs ABSTRACT: The Ising model is one of the simplest statistical mechanics models that displays a phase transition. While invented by Ising and Lenz to model magnetism, for which the Ising model lives on regular lattices, it is now widely used for other real-world applications as a model for cooperative behavior and consensus between people. As such, it is natural to consider the Ising model on complex networks. Since complex networks are modelled using random graphs, this leads us to study the Ising model on random graphs. In this talk, we discuss some recent results on the stationary distribution of the Ising model on locally tree-like random graphs. We start by giving an extensive introduction to random graph models for complex networks, to set the stage of the graphs on which our Ising models live. Real-world networks tend to be highly inhomogeneous, a fact that is most prominently reflected in their degree distributions having heavy tails as described by power laws. Due to the randomness of the graphs on which the Ising model lives, there are different settings for the Ising model on it. The quenched setting describes the Ising model on the random graph as it is, while the averaged quenched setting takes the expectation w.r.t. the randomness of the graph. As such, it takes the expectation of the Boltzman distribution, which is a ratio of an exponential involving the Hamiltonian, and the partition function. In the annealed setting, the expectation is taken on both sides of the ratio. These different settings each describe different physical realities. We discuss the thermodynamic limit of the Ising model, which can be used to define the phase transition in the Ising model on locally tree-like random graphs, by describing when spontaneous magnetization exists and when not, extending work by Dembo and Montanari. We give an explicit expression for the critical value and the critical exponents for the magnetization close to it. These critical exponents depend on the power-law exponent of the degree distribution in the random graph. We also discuss central limit theorems for the total spin in the uniqueness regime, as well as a non-classical limit theorem for the total spin at the critical point in the special setting of the annealed generalized random graph. This talk is based on several joint works with Sander Dommers, Cristian Giardina, Claudio Giberti and Maria Luisa Prioriello.

Seminario di G. Giacomin a Milano-Bicocca (29 maggio 2018)
by Francesco Caravenna 17 May '18

17 May '18

Martedì 29 maggio 2018 alle ore 14:30 Giambattista Giacomin (Université Paris Diderot) terrà un seminario dal titolo "On phase transitions in disordered systems and singular behavior of Lyapunov exponents" Aula 3014, Dipartimento di Matematica e Applicazioni (edificio U5, terzo piano, via Cozzi 55, Milano) Università di Milano-Bicocca Trovate il sommario di seguito. Tutti gli interessati sono invitati a partecipare. Francesco Caravenna %%%%%%%%%%%%%%%%%%%%%%%%%% Abstract: Understanding the effect of disorder on phase transitions and crtical phenomena is a challenging problem that has been repeatedly considered in the phyisics literature. In this domain there is a highly non trivial model that takes the center stage because it is considered to be «exactly solvable». It is the two dimensional Ising model with a special type of disorder («columnar disorder»). I will provide an introduction to this model and to what has been conjectured about it. I will also explain why the exact solvability claim is an overstatement. The solvability aspect in fact is limited to the reduction of the problem to another one - the computation of the Lyapunov exponent of a certain product of two by two random matrices - that seems (and probably is) much easier. In collaboration with Francis Comets and Rafael Greenblatt, we have made some progress toward understanding this product of random matrices. The main aim of the talk is explaining these results and what they imply on the two dimensional Ising model with columnar disorder. %%%%%%%%%%%%%%%%%%%%%%%%%% _________________________________________ 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/ _________________________________________

Colloquium di Balint Toth a Roma Tre il 23 maggio alle 16
by Pietro Caputo 15 May '18

15 May '18

COLLOQUIUM DI MATEMATICA Balint Toth (University of Bristol, UK and Renyi Institute, Budapest) Titolo: Invariance principle for the random Lorentz gas beyond the [Boltzmann-Grad / Gallavotti-Spohn] limit Mercoledi' 23 Maggio 2018 ORE 16:00 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre Aula F, primo piano, edificio Aule - Largo San Leonardo Murialdo,1 Abstract Let hard ball scatterers of radius $r$ be placed in $mathbb R^d$, centred at the points of a Poisson point process of intensity $rho$. The volume fraction $r^d rho$ is assumed to be sufficiently low so that with positive probability the origin is not trapped in a finite domain fully surrounded by scatterers. The Lorentz process is the trajectory of a point-like particle starting from the origin with randomly oriented unit velocity subject to elastic collisions with the fixed (infinite mass) scatterers. The question of diffusive scaling limit of this process is a major open problem in classical statistical physics. Gallavotti (1969) and Spohn (1978) proved that under the so-called Boltzmann-Grad limit, when $r to 0$, $rho to infty$ so that $r^{d-1}rho to 1$ and the time scale is fixed, the Lorentz process (described informally above) converges to a Markovian random flight process, with independent exponentially distributed free flight times and Markovian scatterings. It is essentially straightforward to see that taking a second diffusive scaling limit (after the Gallavotti-Spohn limit) yields invariance principle. I will present new results going beyond the [Boltzmann-Grad / Gallavotti-Spohn] limit, in $d=3$: Letting $r to 0$, $rho to infty$ so that $r^{d-1}rho to 1$ (as in B-G) and simultaneously rescaling time by $T sim r^{-2+epsilon}$ we prove invariance principle (under diffusive scaling) for the Lorentz trajectory. Note that the B-G limit and diffusive scaling are done simultaneously and not in sequel. The proof is essentially based on control of the effect of re-collisions by probabilistic coupling arguments. The main arguments are valid in $d=3$ but not in $d=2$. Joint work with Chris Lutsko (Bristol)

Seminario at Scuola Normale Superiore, Prof. Jean Jacod, Université Paris 6, Pierre et Marie Curie (17-05-2018)
by Giulia 11 May '18

11 May '18

Dear all, On Thursday, 17 May 2018 — at 14:00 — at the Scuola Normale Superiore (Room: Aula Fermi) Prof. Jean Jacod (Université Paris 6, Pierre et Marie Curie) will hold the following Seminar: Title : Modeling asset prices: small scale versus large scale Abstract: A typical model for the price of financial asset, allowing for explicit or numerical computation of option prices, hedging, calibration, etc... , describes the price with an horizon of months or years. In contrast, a very active topic now is concerned with models for tick prices or order books. The structure of the price at the microscopic level is very di_erent from the structure of the usual (often continuous) semimartingales used at a macroscopic level. In particular the microscopic prices evolves on the tick grid, usually going up or down by one tick only. Our aim is to see how it is possible to reconcile the two viewpoints, using a scaling limit of tick-level price models. We will see that this question (going back to the thesis of Bachelier, in a sense) raises a number of non trivial questions if we want a reasonably simple microscopic model, together with a macroscopic model exhibiting stochastic volatility or jumps or a drift. (Joint work with Yacine Ait-Sahalia). Fill free to forward this announcement to your colleagues.

Seminari SOYER e POLSON al CNR IMATI - Milano - 3 Maggio

02 May '18

Ricordo i seguenti seminari che si svolgeranno presso CNR IMATI, via Alfonso Corti 12, Milano, Aula A Giovedì 3 maggio 2018, ore 15:00 - 16:30 [notare il cambio di aula; gentilmente scrivere a simona(a)mi.imati.cnr.it se si intende partecipare] 1) Refik Soyer, School of Business, George Washington University ore 15:00-15:45 BAYESIAN MODELING OF NON GAUSSIAN MULTIVARIATE TIME SERIES Abstract: Modeling of multivariate non Gaussian time series of correlated observations is considered. In so doing, we focus on time series from multivariate counts and durations. Dependence among series arises as a result of sharing a common dynamic environment. We discuss characteristics of the resulting multivariate time series models and develop Bayesian inference for them using particle filtering and Markov chain Monte Carlo methods. We illustrate application of the proposed approach using conditionally multivariate Poisson and gamma time series. Joint work with Tevfik Aktekin, University of New Hampshire and Nicholas Polson, University of Chicago 2) Nicholas Polson, Booth School of Business, University of Chicago ore 15:45-16:30 DEEP LEARNING: A BAYESIAN PERSPECTIVE Deep learning is a form of machine learning for nonlinear high dimensional pattern matching and prediction. By taking a Bayesian probabilistic perspective, we provide a number of insights into more efficient algorithms for optimisation and hyper-parameter tuning. Traditional high-dimensional data reduction techniques, such as principal component analysis (PCA), partial least squares (PLS), reduced rank regression (RRR), projection pursuit regression (PPR) are all shown to be shallow learners. Their deep learning counterparts exploit multiple deep layers of data reduction which provide predictive performance gains. Stochastic gradient descent (SGD) training optimisation and Dropout (DO) regularization provide estimation and variable selection. Bayesian regularization is central to finding weights and connections in networks to optimize the predictive bias-variance trade-off. To illustrate our methodology, we provide an analysis of international bookings on Airbnb. Finally, we conclude with directions for future research.

seminario Marco Patacca in Bicocca
by fabio bellini 02 May '18

02 May '18

Il giorno venerdì 11 maggio alle ore 14.30 presso la Aula Seminari 4026 del DISMEQ al IV piano dell'edificio U7, il dott. Marco Patacca della Università di Perugia terrà un seminario su "Bitcoin prices and market attention" Abstract In this work we measure market attention by applying several filters on time series for the trading volume or the SVI Google searches index. We analyze relative impact of these measures either on the mean or on the variance of Bitcoin returns by fitting non linear econometric models to historical data from January 1, 2012 to December 31, 2017; two non-overlapping subsamples are also considered. Outcomes confirm our conjecture that market attention has an impact on Bitcoin returns. Specifically, trading volume related measures affect both the mean and the conditional variance of Bitcoin returns while internet searches volume mainly affects the conditional variance of returns. Motivated by these evidences we propose a continuous time model for Bitcoin price, we obtain an approximate formula for the likelihood and we fit the model to historical data (joint work with Gianna Figà-Talamanca). Tutti gli interessati sono invitati a partecipare. -- Prof. Fabio Bellini Department of Statistics and Quantitative Methods University of Milano-Bicocca Via Bicocca degli Arcimboldi 8, 20126 Milano 0039-2-64483119 http://scholar.google.it/citations?user=P61L8P4AAAAJ&hl=it

A Winter Day in Probability and Statistical Physics
by Francesca Romana Nardi 27 Apr '18

27 Apr '18

Carissimi, stiamo preparando la prossima giornata di seminari del 16 Marzo 2018 (terzo incontro della serie di giornate sulla probabilita` e le sue applicazioni alla Fisica, Biologia e Scienze sociali). 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). Per maggiori informazioni e aggiornamenti sulle giornate passate e future abbiamo istituito una pagina web che vi invitiamo a visitare periodicamente. http://web.math.unifi.it/users/fnardi/seminari/ A WINTER DAY IN PROBABILITY AND STATISTICAL PHYSICS University of Florence Friday 16 March 2018 Lecturers: Frank den Hollander (Leiden) and Giovanni Peccati (Luxenbourg) Location: Aula Magna di Via S. Gallo 10, Firenze Prof. Frank den Hollander (Leiden University) Title: Large deviations for the Wiener sausage Abstract: The Wiener sausage is the 1-environment of Brownian motion. It is an important mathematical object because it is one of the simplest non-Markovian functionals of Brownian motion. The Wiener sausage has been studied intensively since the 1970's. It plays a key role in the study of various stochastic phenomena, including heat conduction, trapping in random media, spectral properties of random Schrödinger operators, and Bose-Einstein condensation. In these lectures we look at two specific quantities: the volume and the capacity. After an introduction to the Wiener sausage, we show that both the volume and the capacity satisfy a downward large deviation principle. We identify the rate and the rate function, and analyse the properties of the rate function. We also explain how the large deviation principles are proved with the help of the skeleton approach. Joint work with Michiel van den Berg (Bristol) and Erwin Bolthausen (Zurich). Giovanni Peccati (University of Luxembourg) Title: Stein's method and stochastic geometry Abstract: The so-called 'Stein's method' for probabilistic approximations is a collection of powerful analytical techniques, allowing one to explicitly assess the distance between the distributions of two random objects, by using caracterizing differential operators. Originally developed by Ch. Stein at the end of the sixties for dealing with one-dimensional normal approximations under weak dependence assumptions, Stein's method has rapidly become a crucial tool in many areas of modern stochastic analysis, ranging from random matrix theory and random graphs, to mathematical physics, geometry, combinatorics and statistics. In the first part of my talk, I will provide a self-contained introduction to Stein's method for normal approximations, by focussing on some connection with generalised integration by parts formulae, both in a continuous and discrete setting. In the second part of my talk, I will present some recent applications of Stein's method in stochastic geometry, with specific emphasis on the geometry of random fields, and on random geometric graphs.

STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO Venerdì 4 Maggio 2018, alle ore 12:00, presso il nuovo edificio del Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Kolyan RAY (King’s College London) ESTIMATING THE MEAN RESPONSE IN A MISSING DATA MODEL We study semiparametric Bayesian estimation of the mean response in a binary regression model with missing observations. We allow some dependence between the missingness and response mechanisms, which we assume are conditionally independent given some measured covariates (i.e. unconfoundedness). This model has applications in biostatistics and causal inference. We show that the marginal posterior distribution for the mean response arising from product priors on the different model parameters satisfies a semiparametric Bernstein-von Mises theorem under some conditions. We also propose a more involved prior geared towards estimating this specific functional. This is joint work with Aad van der Vaart. ------------------------------------------------ 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.

seminario Dott. Luca Gonzato
by emanuela rosazza gianin 27 Apr '18

27 Apr '18

Si avvisa che il giorno mercoledì 2 maggio alle ore 14.30 presso l’Università di Milano- Bicocca (via degli Arcimboldi 8 - edificio U7, quarto piano- aula seminari 4026) si terrà il seguente seminario: Speaker: Luca Gonzato (Dismeq, Università di Milano-Bicocca) Titolo: “ Filtering and Calibrating a Self-Exciting Jump Diffusion Model for Oil Price by a Particle Markov Chain Monte Carlo Method ” Abstract: In this paper we propose a self-exciting jump diffusion model for oil price dynamics based on a Hawkes-type process. In particular, the jump intensity is stochastic and path dependent; so a jump will increase the probability of observing a new jump and this feature of the model aims at explaining the jumps clustering effect. Our model is very similar to that proposed by Hainaut & Moraux (2017) for equity market, although we assume the jump size normally distributed. Moreover, our filtering and calibration method relies on a different procedure. Indeed, we filter the latent jump intensity and estimate the model parameters according to a Particle Markov Chain Monte Carlo method proposed by Andrieu, Doucet & Holenstein (2010), which is well suited for nonlinear non-Gaussian dynamical models. Finally, we provide numerical simulations in order to test our approach. Joint work with Carlo Sgarra. Tutti gli interessati sono invitati a partecipare.
