Cari Colleghi,
vi segnalo il seguente seminario, in modalità ibrida, della serie dei MOX COLLOQUIA:
10.04.25 Ore 14:30 - Aula IV, Edificio 11, Politecnico di Milano
Speaker: Mihaela van der Schaar, Faculty of Mathematics, University of Cambridge
Titolo: Can we discover fundamental laws from data using AI?
Abstract:
Discovering fundamental laws governing systems from observational data has long been a hallmark of scientific inquiry. In this talk, I will discuss how recent advances in AI and …
[View More]machine learning enable the automated discovery of scientific laws and governing equations directly from data, revolutionizing the way we unravel system dynamics in numerous domains, including medicine and pharmacology. I will highlight how AI-driven methods uncover underlying principles, from classical physics to biological systems to medicine, and offer insights into future possibilities—transforming data-driven observations into interpretable and actionable scientific knowledge. Yet, can we push this boundary further—going beyond equations entirely? I will introduce direct semantic modeling, a novel paradigm where AI learns the behavior of dynamical systems directly from data without relying on closed-form equations. This semantic approach offers intuitive, human-interpretable insights into system evolution, marking a transformative leap in scientific discovery. (This talk is based on recent research with Krzysztof Kacprzyk, Tennison Liu and Sam Holt.)

Title: A stochastic Gordon-Loeb model for optimal security investment under clustered cyber-attacks.
Abstract: We propose a continuous-time extension of the Gordon-Loeb model for optimal …
[View More]investment in information security under the threat of cyber-attacks. The arrival of attacks is modeled using Hawkes processes, capturing the realistic feature of clustering in cyber-attacks. Each attack may lead to a system breach, with the probability of breach depending on the system's vulnerability. We aim at determining the optimal investment in cyber-security to reduce the system's vulnerability. The problem is formulated as a two-dimensional Markovian stochastic control problem and solved via dynamic programming techniques. We perform a numerical study of the value function and the associated optimal investment strategy in cyber-security, highlighting the impact of randomly arriving clustered cyber-attacks. Based on a joint work with G. Callegaro, C. Hillairet, B. Ongarato.
Next seminar: Alessandro Sbuelz (Università Cattolica del Sacro Cuore), 7 May 12.15.

*Arnaud Debussche*
(ENS Rennes, France)
will speak about
*From correlated to white transport noise in fluid models*
Abstract: Stochastic fluid models with transport noise are popular, the
transport noise models unresolved small scales. The main assumption in
these models is a very strong separation of scales allowing this
representation of small scales by white - i.e. fully decorrelated -
noise. It is therefore natural to investigate whether these models are
limits of models with correlated noises. Also, an advantage of
correlated noises is that they allow classical calculus. In particular,
it allows to revisit the derivation of stochastic models from
variational principles and allows to derive an equation for the
evolution of the noise components. The advantage of having such an
equation is that in most works, the noise components are considered as
given and stationary with respect to time which is non realistic.
Coupling stochastic fluid models with these gives more realistic systems.
===== about the speaker ====
Arnaud Debussche is a prominent French mathematician specializing in
stochastic partial differential equations and their applications. Born
in 1965, he attended the École Normale Supérieure de Saint-Cloud,where
he pursued advanced studies in mathematics. He earned his Ph.D. from
Université d'Orsay in 1989. Following a postdoctoral position at Indiana
University, he joined the National Center for Scientific Research (CNRS)
in 1992. In 2000, he became a full professor at the École Normale
Supérieure de Rennes, where he continues to contribute significantly to
the field. Throughout his career, Professor Debussche has made
substantial contributions to the analysis and numerical simulation of
stochastic partial differential equations, particularly in fluid
dynamics. His work includes studies on the stochastic Navier–Stokes
equations and the stochastic nonlinear Schrödinger equation. He has also
co-edited scholarly works on stochastic partial differential equations,
reflecting his active engagement in advancing mathematical understanding
in this area. Professor Debussche's research has been widely recognized
and cited, underscoring his influence in the mathematical community. His
ongoing work continues to shape the study of stochastic processes and
their applications in complex systems.

RELATORI: Stefano Favaro (Università di Torino) e Mario Beraha (Università
di Milano Bicocca)
TITOLO: Il modello di Ewens-Pitman per partizioni aleatorie e la sua
(naturale) estensione alle allocazioni aleatorie
RIASSUNTO: Nella prima parte del seminario verrà introdotto il modello di
Ewens-Pitman per partizioni aleatorie, presentandone una caratterizzazione
in termini di sufficienza predittiva nell’ambito della classe dei modelli
di campionamento di specie. Successivamente, verrà offerta una panoramica
sui principali teoremi limite relativi al numero di blocchi e blocchi con
molteplicità della partizione di Ewens-Pitman, con particolare attenzione
alle fluttuazioni quasi-certe, ai principi di grandi deviazioni e alle
fluttuazioni Gaussiane. Infine, si illustrerà un’applicazione del modello
di Ewens-Pitman alla soluzione Bayesiana del problema della stima della
“missing mass”, noto come problema di Good-Turing, e della stima del
“unseen”, o problema di Fisher-Efron.
Nella seconda parte del seminario si parlerà di allocazioni aleatorie;
un’allocazione di N oggetti è un multi-insieme di sottoinsiemi non vuoti
degli N oggetti che, al contrario di una partizione, possono non essere
mutuamente esclusivi o esaustivi. Partendo dal modello Indian buffet di
Ghahramani e Griffiths, che costituisce il naturale analogo del modello di
Ewens nel caso di allocazioni, verranno presentati alcuni risultati
sull’analisi Bayesiana di allocazioni aleatorie. In particolare, verranno
discusse caratterizzazioni di sufficienza predittiva per allocazioni
aleatorie, che generalizzano i corrispondenti risultati sui modelli di
campionamento di specie. Due illustrazioni relative al problema delle
“missing features” verranno descritte.
