Seminar: Adriano Barra at Tor Vergata 02.11
by Michele Salvi 22 Mar '24

22 Mar '24

Dear all, On Thursday, November 2nd, at 15h00 in Aula Dal Passo of Tor Vergata Math Department, RoMaDS (https://www.mat.uniroma2.it/~rds/about.php) will host Adriano Barra (Università del Salento) with the seminar "A walk in the statistical mechanics of neural networks” Abstract: Purpose of this talk is twofold: in the first part, I will provide a statistical mechanical picture of shallow networks proving how learning in biological neural networks (e.g. in the Hopfield model) and standard machine learning via gradient descent (e.g. on the Boltzmann machine) ultimately convey the same information after training. This diminishes the gap in our understanding between biological and artificial information processing networks. In the second part of the talk, focusing on a toy model for the sake of simplicity, I will show how recent mathematical techniques, heavily based on Guerra's interpolation, are suitable to describe the emergent properties of this kind of networks. We encourage in-person partecipation. Should you be unable to come, here is the link to the Teams streaming: https://teams.microsoft.com/l/meetup-join/19%3arfsL73KX-fw86y1YnXq2nk5VnZFw… <https://teams.microsoft.com/l/meetup-join/19:rfsL73KX-fw86y1YnXq2nk5VnZFwPU…> The seminar is part of the Excellence Project MatMod@TOV.

Dear all, We are happy to announce that on Monday, September 25th, at 15h00 in Aula Dal Passo of Tor Vergata Math Department, RoMaDS (https://www.mat.uniroma2.it/~rds/about.php) will host Marco Carfagnini (University of California San Diego) with the seminar "Spectral gaps via small deviations” Abstract: In this talk we will discuss spectral gaps of second order differential operators and their connection to limit laws such as small deviations and Chung’s laws of the iterated logarithm. The main focus is on hypoelliptic diffusions such as the Kolmogorov diffusion and horizontal Brownian motions on Carnot groups. If time permits, we will discuss spectral properties and existence of spectral gaps on general Dirichlet metric measure spaces.This talk is based on joint works with Maria (Masha) Gordina and Alexander (Sasha) Teplyaev. We encourage in-person partecipation.

de Finetti seminar: 8 November, 16:30
by Marco Maggis 26 Oct '23

26 Oct '23

On behalf of the Scientific Committee of the "B. de Finetti Risk Seminars, Milano Lectures on the Mathematical Theory of Economics and Finance”, we are glad to invite you to participate at the following lecture: Umut Cetin London School of Economics Title: *Insider trading with penalties and BSDEs* Abstract: We study equilibrium in a continuous time Kyle-Back model with a risk neutral informed trader whose trades are subject to costs, which can also be viewed as legal penalties for illegal insider trading if caught by the authorities. Existence of equilibrium is established under certain assumptions on the asset’s terminal payoff. Informed trader’s value function is related to a BSDE whose terminal condition is determined in equilibrium, which turns out to be the fixed point of a nonlinear operator. Equilibrium also reveals an interesting connection between h-transforms and quadratic BSDEs. LOCATION: The seminar will be held on *November 8, *2023 at *16.30,* Aula Di Rappresentanza, Dipart.

Seminar in Statistics - PATRICK REBESCHINI

23 Oct '23

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 27 Ottobre 2023, alle ore 12.00, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Speaker: *Patrick Rebeschini* (Oxford University, UK) Title: *Algorithmic Stability, Generalization, and Privacy for Diffusion Models* Abstract: The acclaimed success of diffusion models sparks a need to formulate theoretical guarantees to explain the generalization capability of such distribution learning methods, despite the high-dimensional nature of the training data and sampling procedures being utilized. Prior efforts accounting for the empirical nature of score matching mechanisms typically hinge on uniform learning strategies, which provide error bounds that are algorithm-agnostic and often yield results that depend exponentially badly on the problem dimension. In this work, we move away from uniform learning approaches and develop algorithm-dependent generalization error bounds based on the framework of algorithmic stability from supervised learning. We introduce the notion of 'score stability’, which encapsulates the score learning process's susceptibility to perturbations in the training data. We show that score-stable algorithms generalize well and generate differentially-private samples. To showcase the applicability of our framework, we consider score functions learned via canonical gradient-based optimization procedures, and establish generalization bounds that display a linear dependence on the dimension. Our bounds are stated with respect to the reverse KL divergence and the maximum mean discrepancy, notions of error commonly used in the analysis and training of diffusion models. (Joint work with Tyler Farghly, George Deligiannidis, and Arnaud Doucet) ------------------------------------------------ Sarà possibile seguire il seminario anche in streaming: Join Zoom Meeting <https://us02web.zoom.us/j/88107896961?pwd=TFZhS01BS3IzZmtSRWZNTWJhNHRNQT09> 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/>

Zanco https://sites.google.com/unipi.it/spass <https://www.google.com/url?q=https://sites.google.com/unipi.it/spass&source…> ------------------------------------------- Abstract: We prove the existence of solutions to a non-linear, non-local, degenerate equation which was previously derived as the formal hydrodynamic limit of an active Brownian particle system, where the particles are endowed with a position and an orientation. This equation incorporates diffusion in both the spatial and angular coordinates, as well as a non-linear non-local drift term, which depends on the angle-independent density. The spatial diffusion is non-linear degenerate and also comprises diffusion of the angle-independent density, which one may interpret as cross-diffusion with infinitely many species. Our proof relies on interpreting the equation as the perturbation of a gradient flow in a Wasserstein-type space. It generalizes the boundedness-by-entropy method to this setting and makes use of a gain of integrability due to the angular diffusion. We also prove uniqueness in the particular case where the non-local drift term is null, and provide existence and uniqueness results for stationary equilibrium solutions. This is joint work with Martin Burger.

Gentili colleghe/i, inoltro un invito a manifestare interesse per posizioni da assegnista di ricerca che verranno bandite a breve dall’Università Bocconi. Cordiali saluti, Antonio Lijoi ------------ ** Call for expression of interest ** The Bocconi Institute for Data Science and Analytics (BIDSA) will soon open two post-doctoral positions on Bayesian Nonparametrics, under the supervision of Antonio Lijoi and Igor Pruenster. The start date should ideally be in early 2024 but there is some space for flexibility. Successful applicants will be based at the BayesLab (https://bayeslab.unibocconi.eu), a BIDSA research unit focusing on Bayesian learning. Potentially interested candidates are strongly encouraged to contact Antonio Lijoi (antonio.lijoi(a)unibocconi.it) or Igor Pruenster (igor(a)unibocconi.it) for further details, possibly before November 1, 2023.

Seminars at Sapienza Univ. - 23-24 Oct.
by Luisa Beghin 19 Oct '23

19 Oct '23

Dear all, we are pleased to invite you to the two seminars organised by the Department of Statistical Sciences, Sapienza University of Rome, which can be followed via Zoom. *Location:* Room n.24, 4th floor, Edificio CU002 (Scienze Statistiche) *Zoom: * https://uniroma1.zoom.us/j/84380852385?pwd=RDBrcVdvelRMM0VmczlXYWgwL2pPZz09 *Time:* *Monday 23th of October, at 10.30* *Speaker: *Josè Luis Da Silva (University of Madeira - Portugal) *Title:* A Biorthogonal Approach to Infinite Dimensional Fractional Poisson Measures *Abstract*: We use a biorthogonal approach to the analysis of the infinite dimensional fractional Poisson measure. The complex Hilbert space w.r.t. these measures are described in terms of a proper system of generalized Appell polynomials. The kernels of the monomials may be expressed in terms of the Stirling operators of the first and second kind as well as the falling factorials in infinite dimensions. Associated to this system of Appell polynomials is the dual Appell system which is suitable to describe generalised functions. We then construct and characterize test and generalised functions in terms of integral transform as entire functions. *Time:* *Tuesday 24th of October, at 14.30* *Speaker: *Tobias Kuna (University of L'Aquila) *Title:* An Intrinsic Characterization of Moment Functionals in the Compact Case *Abstract:* We discuss characterizations of linear functionals $L$ on an unital commutative real algebra $A$ which can be represented as integral w.r.t. a compactly supported Radon measure on the character space of $A$. We give a characterization by the following three types of conditions: bounds on the growth of $(L(a^n))_n$, non-negativity of $L$ on Archimedean quadratic models, and continuity of $L$ w.r.t. submultiplicative seminorms on $A$. We will relate each of these conditions to a different technique solving this instance of the moment problem. Surprisingly, we can also provide an exact characterization of the compact support of the representing Radon measure purely in terms of $L$. This is a joint work arXiv:2204.05630 with Maria Infusino, Salma Kuhlmann and Patrick Michalski. Best regards.
