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.

Seminar: Alessandra Menafoglio March 12, 2024, Ca' Foscari University of Venice
by Carlo Gaetan 29 Feb '24

29 Feb '24

Dear all, we are glad to announce the following hybrid seminar *March 12, 2024, 12:15 PM* *Where*: Aula Delta 2C- edificio Zeta (Campus Scientifico), Via Torino, 155 Mestre (Venice, Italy) Zoom: https://unive.zoom.us/j/85153268624?pwd=MzBhdlA2M1B2dThJQ2Y5T0EwUE5PZz09 *Speaker*: Alessandra Menafoglio, Politecnico di Milano (Milano, Italy) *Title*: The Bayes space approach to functional data analysis for probability density functions *Abstract:* In the presence of increasingly massive and heterogeneous data, the statistical modeling of distributional observations plays a key role. Choosing the ‘right’ embedding space for these data is of paramount importance for their statistical processing, to account for their nature and inherent constraints. The Bayes space theory is a natural embedding space for (spatial) distributional data, and was successfully applied in varied settings. In this presentation, I will discuss the state-of-the-art methods for the modelling, analysis, and prediction of distributional data, with a particular attention to cases when their spatial dependence cannot be neglected. I will embrace the viewpoint of object-oriented spatial statistics (O2S2), a system of ideas for the analysis of complex data with spatial dependence. All the theoretical developments will be illustrated through their application on real data, highlighting the intrinsic challenges of a statistical analysis which follows the Bayes spaces approach.

1 Year Post-Doc position in Verona
by Alessandro Gnoatto 29 Feb '24

29 Feb '24

1 Year Post-Doc position in Verona I am looking for a post-doc to join my group. The topic of the research project is "Machine learning and stochastic control for financial risk management" The aim of this project is to study new methods, models, and numerical techniques for the treatment of financial risk management problems, in particular counterparty credit risk (xVA) or the pricing of financial and insurance claims. Many problems in finance involve the minimization of a cost functional subject to controlled stochastic state variables. Controls or related quantities in high dimension can be conveniently approximated by means of artificial neural networks. The aim of the project is to study control problems and partial (integro) differential equations under general dynamics together with the development of new models for the evolution of risk factors, with a special focus on interest rates. The candidate should have a solid background in probability, stochastic calculus and computational finance. Experience with the Java and/or Python programming languages and Machine Learning frameworks such as Tensorflow, Deep Java Library or Deeplearning4J is a plus. Candidates will be evaluated based on their scientific quality and their potential in developing research. There are no teaching obligations and knowledge of Italian is not required. The deadline for applications is the 19 March 2024 (h. 13.00). The link to the call is here https://docs.univr.it/documenti/Concorso/bando/bando371360.pdf The call is in Italian. Non-Italian speakers needing help with the form can contact me at alessandro [dot] gnoatto [at] univr [dot] it I am happy to help. The Economics Department of the University of Verona has been recognized as "Department of Excellence" ("Dipartimento di Eccellenza") in the latest Italian Government Research Quality Evaluation Procedure.

Seminario Ilya Losev - Lunedì 4 Marzo - Sapienza Università di Roma
by Silvestri, Vittoria 26 Feb '24

26 Feb '24

Si segnala il seguente seminario: Lunedì 4 Marzo 2024, ore 16:00, Sala di Consiglio, Dipartimento di Matematica "Guido Castelnuovo", Sapienza Università di Roma. *Speaker: *Ilya Losev (University of Cambridge, UK) *Title: *How long are the arms in Dielectric-Breakdown Model? *Abstract: *In this talk we will discuss the recent progress on such random growth models as Diffusion Limited Aggregation (DLA) and Dielectric-Breakdown Model (DBM) in 2 and 3 dimensions. These models are believed to exhibit non-equilibrium growth, producing irregular fractal patterns. The main questions about these processes include finding their scaling limits and fractal dimensions. However, almost nothing is known rigorously. The main result about these models is due to Kesten, who gave a non-trivial lower bound on the fractal dimension of DLA clusters. The main tool in his proof was the famous Beurling’s estimate. We generalize this result to DBM and give a new proof of Kesten’s Theorem. Our proof does not rely on Beurling’s estimate. Instead, we exploit the connection between DBM growth properties and multifractal spectrum of the harmonic measure. ******************************** Vittoria Silvestri Assistant Professor Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome ********************************
