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. Matematica, Università di Milano, Via Saldini 50, Milano. Scientific Committee: Prof. Simone Cerreia-Vioglio (Univ. Bocconi) Prof. Marco Frittelli (Univ. degli Studi di Milano) Prof. Fabio Maccheroni (Univ. Bocconi) Prof. Marco Maggis (Univ. degli Studi di Milano) Prof. Massimo Marinacci (Univ. Bocconi) Prof. Emanuela Rosazza Gianin (Univ. Milano-Bicocca)

Seminar in Statistics - PATRICK REBESCHINI
by Pierpaolo De Blasi 23 Oct '23

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/>

SPASS Seminar: Simon Michaël Schulz
by Francesco Grotto 20 Oct '23

20 Oct '23

Dear Colleagues, We would like to invite you to the following SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi (abstract below): *Well-posedness and stationary states for a crowded active Brownian system with size-exclusion* by *Simon Michaël Schulz* (Scuola Normale Superiore) The seminar will take place on *TUE, 24.10.2023* at *14:00 CET *in Aula Seminari, Dipartimento di Matematica, University of 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 <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.
