Two classes of quantile diffusions are identified: the first, which we largely focus on, features a dynamic random quantile level that allows for direct interpretation of the resulting quantile process characteristics such as location, scale, skewness, and kurtosis, in terms of the model parameters. The second type are function--valued quantile diffusions and are driven by stochastic parameter processes, which determine the entire quantile function at each point in time. By the proposed construction method, quantile processes are obtained by transforming the marginals of a diffusion process under a composite map consisting of a distribution and a quantile function. Sub-classes of quantile diffusions are explored, with emphasis placed on the Tukey family of models whereby skewness and kurtosis are directly parameterised and thus the composite map is explicable with respect to such statistical behaviours. As an example of an application of quantile diffusions, we show how probability measure distortions, a form of dynamic tilting, can be induced. Though particularly useful in financial mathematics and actuarial science, examples of which are given in this work, measure distortions feature across multiple research areas. For instance, dynamic distributional approximations (statistics), non-parametric and asymptotic analysis (mathematical statistics), dynamic risk measures (econometrics), behavioural economics, decision making (operations research), signal processing (information theory), and not least in general risk theory including applications thereof.

Seminars in Statistics at Collegio Carlo Alberto - Sahani PATHIRAJA (UNSW SYDNEY) and Quan ZHOU (TEXAS AMU)
by Matteo Giordano 08 Mar '25

08 Mar '25

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.google.com/url?q=https://www.carloalberto.org/events/category/s…> Venerdì 14/03/2025, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente doppio seminario: ------------------------------------------------ 11.00-12.00 Speaker: Sahani PATHIRAJA (UNSW SYDNEY) Title: ON CONNECTIONS BETWEEN SEQUENTIAL BAYESIAN INFERENCE AND EVOLUTIONARY DYNAMICS Abstract: It has long been posited that there is a connection between the dynamical equations describing birth-death & evolutionary processes in biology (so-called ``replicator-mutator’’ dynamics) and sequential Bayesian learning methods. This talk describes new research in which this precise connection is rigorously established in the continuous time setting. Here we focus on a class of interacting particle methods for solving the sequential Bayesian inference problem which are characterised by a McKean-Vlasov Stochastic differential equation. Of particular importance is a piecewise smooth approximation of the observation path from which the discrete time filtering equations are shown to converge to a Stratonovich interpretation of the Kushner equation. This smooth formulation will then be used to draw precise connections between nonlinear filtering and replicator-mutator dynamics. Additionally, gradient flow formulations will be investigated as well as a particular form of replicator-mutator dynamics which is shown to be beneficial for filtering with misspecified models. It is hoped this work will spur further research into exchanges between sequential learning and evolutionary biology and to inspire new algorithms in filtering and sampling. 12.00-13.00 Speaker: Quan ZHOU (TEXAS AMU) Title: GENERATIVE MODELING USING SOFT-CONSTRAINED SCHRODINGER BRIDGE Abstract: Schrodinger bridge can be viewed as a continuous-time stochastic control problem where the goal is to find an optimally controlled diffusion process whose terminal distribution coincides with a pre-specified target distribution. We propose to generalize this problem by allowing the terminal distribution to differ from the target but penalizing the Kullback-Leibler divergence between the two distributions. We call this new control problem soft-constrained Schrodinger bridge (SSB). The main contribution of this work is a theoretical derivation of the solution to SSB, which shows that the terminal distribution of the optimally controlled process is a geometric mixture of the target and some other distribution. This result is further extended to a time series setting. One application is the development of robust generative diffusion models. We propose a score matching-based algorithm for sampling from geometric mixtures and showcase its use via a numerical example for the MNIST data set. Joint work with J. Garg and X.

Dear colleagues, We are pleased to announce the upcoming StatPhys29 Satellite Conference: "Non-equilibrium statistical physics: mathematical and physical advances", Florence 21-25 July 2025: https://sites.google.com/view/nesp-2025 Research on non-equilibrium statistical physics has been developing rapidly and today represents a theme of growing interest worldwide. Fundamental ideas, methods and techniques have gradually made their way from statistical physics into probability theory and mathematical physics, where they lead to new problems and new solutions. This crossroad has developed into a very active research area over the past 10 years. In the proposed workshop the focus is on common concepts and tools and on the surprising new connections that have become available recently. Key topics that will be addressed at the conference are: (1) Non-equilibrium steady states of classical, quantum, and stochastic systems; (2) KPZ universality; (3) integrable quantum dynamics; (4) hydrodynamic limit and large deviations; (5) anomalous transport. The satellite meeting aims at gathering major experts in these fields, with the goal of exchanging ideas and setting the stage for further progress. Registration Details: This Satellite Conference is open to everybody. There is the possibility of a few contributed talks. • Deadline: April 30, 2025. • Please register via https://sites.google.com/view/nesp-2025 • There is no registration fee. Feel free to share this invitation with anyone who may be interested. Best regards, L. Avena, F. Colomo, C. Giardina', P. Goncalvez, F. Essler, T. Sasamoto, H. Spohn.

This classical approach is nevertheless challenged by empirical data for model validation, especially when the phenomenon of interest does not depend on well established physical laws. In particular the statistical inference of parameters (estimation and testing) requires a underlying stochastic model. This is usullay treated via some addition of noise, sometimes artificially and always a bit arbitrarily. Relying on some specific examples that appear in population biology (cell growth, human demography) or agent-based models in economy, we propose an alternative approach. Starting from a microscopic stochastic model that can be partially observed and for which the PDE of interest is a mean-field limit, the intrinsic statistical noise becomes the fluctuation between the empirical measure of the particle system and the solution of the PDE. We will outline a rigorous statistical program in this setting and will give some results on McKean-Vlasov models that shall emphasise the interest of our approach. Vi aspettiamo numerosi!

Fwd: International Seminar on SDEs and Related Topics: Laurent Denis - March14
by Gianmario Tessitore - UNIMIB 06 Mar '25

06 Mar '25

Diffondo con piacere Mario ============================================================================ Dear Colleague, *on Friday, March 14,* (12:30 noon London, 1:30 pm Berlin, 2:30 pm Helsinki, 8:30 pm Beijing) in the *International Seminar on SDEs and Related Topics* in Zoom https://jyufi.zoom.us/j/61891007917 *Laurent Denis* (Université du Maine, France) will speak about */BSDE with singular terminal condition: the continuity up to terminal time problem/ * Abstract: We study the limit behavior of the solution of a backward stochastic differential equation when the terminal condition is singular, that is it can be equal to infinity with a positive probability. In the Markovian setting and in the case where the equation is driven by a Brownian motion, Malliavin's calculus enables us to prove continuity if a balance condition between the growth w.r.t. /y/ and the growth w.r.t. /z/ of the generator is satisfied. We apply our result to liquidity problem in finance and to the solution of some semi-linear partial differential equation ; the imposed assumption is also new in the literature on PDE. Finally, we prove that if there are jumps (i.e. the operator of the PDE is non local), we observe a propagation of the singularity, contrary to the continuous case (local operator). This talk is based on several joint works with D. Cacitti-Holland and A. Popier. References: Cacitti-Holland D., Denis L., Popier A. Continuity problem for BSDE and IPDE with singular terminal condition,/Journal of Mathematical Analysis and Applications/, Vol. 543, issue 1 (2025). Cacitti-Holland D., Denis L., Popier A. Growth condition on the generator of BSDE with singular terminal value ensuring continuity up to terminal time, to appear in /Stochastic Processes and their Applications/ (2025).

OWPS is back next week!
by Luisa Andreis 05 Mar '25

05 Mar '25

Dear colleagues, We are delighted to announce that the One World Probability Seminar is returning for the Spring 2025 semester with a refreshed schedule! The seminar will be held every other Wednesday at 14:00 UTC. The season will kick off on Wednesday, March 12 at 14:00 UTC via Zoom (link<https://polimi-it.zoom.us/j/92945513591?pwd=zjtRwpHoO9kRyQuPPj4o186jXrvg1v.1>). We are thrilled to welcome our first two speakers: Shankar Bhamidi (University of North Carolina) and David J. Aldous (UC Berkeley) Please find titles and abstracts of their talks below and on our website<https://www.owprobability.org/about>, which also contains future speakers for the semester. Originally launched during the early days of the pandemic to keep the probability community connected, our seminar has since hosted over 100 research talks from around the globe. It remains open to anyone eager to learn about the latest developments in probability theory. We encourage you to share this announcement as we embark on this new chapter. If you want updates on future OWP seminars, consider joining our mailing list: here<https://www.owprobability.org/mailing-list> the instructions. We look forward to seeing many of you online! Best wishes, Luisa Andreis and Roger Van Peski Aldous’s fringe convergence of random trees and its applications Shankar Bhamidi (UNC Chapel Hill) Local weak convergence starting with the work of Aldous and Benjamini and Schramm has turned out to be one of the standard work horses in modern probabilistic combinatorics, to understand asymptotics of large discrete random structures and dynamics of processes such as random walks on such processes. The goal of this talk is to describe the impact of one of the less well known “OG” (original great) papers in this area: Aldous’s work on fringe convergence of random trees developed in a paper in the mid 90s. This technique, coupled with stochastic approximation techniques allows one to relatively easily prove local weak convergence of a number of modern random tree models proposed by domain scientists, including network evolution with limited choice, network dynamics where new individuals have access to only a partial temporal snapshot of the network and network evolution models where individuals have different attributes. Obscure results and open problems: some of my favorites David J. Aldous (UC Berkeley) These are some problems that I would like some smart young person to work on! (1) What probability distributions on $[0,\infty)$ arise as the distance between two i.i.d. points in some complete separable metric space? (2) Probability distributions on routed planar networks. (3) Combinatorics of fringe trees in a phylogenetic model. (4) Nearest neighbor of nearest neighbor, on the complete network -- Are you smarter than an AI? (5) Find a qualitatively realistic model for a generic subway network. (6) Percolation of empires.

ABS25 (Applied Bayesian Statistics) summer school in Genova, Italy, 3-6/6/2025
by Elisa Varini 05 Mar '25

05 Mar '25

We are pleased to inform you that registration and fee payment are now possible for the next Applied Bayesian Statistics summer school - ABS25 to be held from 3 to 6 June 2025 in the beautiful historic city of Genova, overlooking the Ligurian Sea in Italy. Website: https://abs25.imati.cnr.it/ <https://abs25.imati.cnr.it/> The school is organized by CNR IMATI (Institute of Applied Mathematics and Information Technologies at the Italian National Research Council in Milano), in cooperation with the Department of Mathematics of the University of Genova. The topic will be SPATIO-TEMPORAL METHODS IN ENVIRONMENTAL EPIDEMIOLOGY The lecturer will be Prof. ALEXANDRA SCHMIDT (McGill University, Department of Epidemiology, Biostatistics and Occupational Health, Canada), with the support of Dr. CARLO ZACCARDI (University G. d'Annunzio Chieti-Pescara, Department of Economics, Italy). As in the past (since 2004), there will be a combination of theoretical and practical sessions, along with presentations by participants about their work (past, current and future) related to the topic of the school. OUTLINE: This course aims to explore the interface between environmental epidemiology (EE) and spatio-temporal modelling (ST). The aim of EE is to understand the adverse health effects of environmental hazards and to estimate the risks associated with those hazards. Such risks have traditionally been assessed either over time at a fixed point in space or over space at a fixed point in time. ST modelling characterizes the distribution of those hazards and associated risks over both geographical locations and time. Understanding variation and exploiting dependencies over both space and time greatly increases the power to assess those relationships. The course will cover a wide range of topics from an introduction to spatio-temporal and epidemiological principles along with the foundations of ST modeling, with specific focus on their application, to new directions for research. Topics to be covered: - Types of epidemiological studies: cohort, case–control, ecological - Measures of risk: relative risks, odds ratios, absolute risk, sources of bias, assessing uncertainty - Bayesian statistics and computational techniques: Markov Chain Monte Carlo (MCMC) - Regression models in epidemiology: Logistic and Poisson generalized linear models, hierarchical models - Dynamic linear models, temporal autocorrelation - Spatial models: area and point referenced methods, mapping, geostatistical methods, spatial regression - Spatial-temporal models: separable models, non-separable models, modelling exposures in space and time.

Seminario Matteo Brachetta - Politecnico di Milano - 13 Marzo 2025
by Luca Scarpa 04 Mar '25

04 Mar '25

Si segnala il seguente seminario a tutti gli interessati. Giovedì 13 Marzo 2025, ore 11:45. Aula Seminari VI Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Matteo Brachetta, Università di Genova. Title: Risk measures and optimal reinsurance: finding a connection via BSDEs. Abstract: The aim of this talk is to connect utiility maximization problems and the optimization of dynamic risk measures, which are usually considered as two different branches or approaches to financial problems. A reinsurance contract allows an insurance company to transfer part of the risk to another company, namely the reinsurer, in order to reduce the future losses, which are usually modeled as a marked point process. Finding the optimal reinsurance agreement translates into a stochastic control problem for the insurer. Recently, some authors showed that the optimal value process for the utility maximization problem can be characterized as the solution of a BSDE with jumps. In other works, it is proved that some BSDEs induce dynamic risk measures, which can be financially interpreted as a default time and an associated mark. In this talk we aim to explore the properties of the risk measure induced by the optimal reinsurance policy under dierent risk models with jumps. The talk is based on a work in progress with Fulvia Confortola (Politecnico of Milan).

Si segnala il seguente seminario a tutti gli interessati. Giovedì 13 Marzo 2025, ore 11:00. Aula Seminari VI Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Elena Montanaro, Università La Sapienza. Title: An epidemic model using GW trees and coupon collectors. Abstract: We describe a model for information or viral transmission on the complete graph $\mathbb{K}_n$. Each node is an individual which may be susceptible, infected or recovered. This model has been introduced by Comets et al. with the main goal of studying the asymptotic behavior, as $n$ goes to infinity, of the duration of the infection and of the proportion of infected individuals in the population. The results rely on two interesting stochastic processes: the GW process and the coupon collector process.
