I seminari verranno trasmessi via Zoom al seguente link: https://unipd.zoom.us/j/81175434050?pwd=hCozT8gqnlu49Io6LawZWAwLDrnaJ7.1 Meeting ID: 811 7543 4050 Passcode: 871716 Vi aspettiamo numerosi! Alberto Chiarini e Sonia Mazzucchi %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Giuseppe Cannizzaro (University of Warwick) e Fabio Toninelli (Technical University of Vienna) TITOLO: Teorema del Limite Centrale superdiffusivo per l'equazione di Burgers stocastica alla dimensione critica RIASSUNTO: L'equazione di Burgers Stocastica (EBS) è stata introdotta da van Beijren, Kutner and Spohn per modellizzare sistemi diffusivi asimmetrici con una singola quantità conservata (e.g. il modello di esclusione semplice asimmetrico). Nella dimensione sub-critica d=1, EBS coincide con la derivata dell'equazione KPZ il cui comportamento a grandi scale è superdiffusivo con crescita polinomiale e le cui fluttuazioni coincidono con il KPZ Fixed Point, mentre nelle dimensioni super-critiche d>2, è diffusivo e converge a un'equazione del calore stocastica anisotropica. Alla dimensione critica, è stato congetturato che la EBS sia superdiffusiva con crescita logaritmica con un esponente preciso ma ciò è stato mostrato solo modulo correzioni di ordine inferiore. Il presente seminario è basato su un lavoro assieme a Quentin Moulard https://arxiv.org/abs/2501.00344, in cui indentifichiamo la superdiffusività e deriviamo le asintotiche della matrice di diffusione in modo esatto. Inoltre, dimostriamo che nel limite di scala corretto, ovvero che tiene presente della crescita logaritmiche alla diffusività, la soluzione di EBS soddisfa un teorema del limite centrale. Il nostro è il primo limite di scala superdiffusivo per un'equazione alle derivate parziali stocastica critica, al di là dell'ambito di applicabilità della teoria delle strutture di regolarità di Hairer. %%%%%%%%%%%%%%%%%%%%%%%%%%%%

Seminari Padova - Claudio Macci e Jonathan Tam
by alekos.cecchin＠unipd.it 14 Feb '25

14 Feb '25

Buongiorno a tutti, Vorremmo segnalarvi che venerdì prossimo (21 Febbraio) in aula 1BC45 (Torre Archimede, Università di Padova) ci saranno due seminari per il ciclo di seminari in Probabilità e Finanza di: 1. Claudio Macci (Università di Roma Tor Vergata) <https://www.mat.uniroma2.it/~macci/> https://www.mat.uniroma2.it/~macci/ Title: Large and moderate deviations for Gaussian neural networks Date: February 21, 2025, at 14:30, room 1BC45 Abstract: We prove large and moderate deviations for the output of Gaussian fully connected neural networks. The main achievements concern deep neural networks (i.e., when the model has more than one hidden layer) and hold for bounded and continuous pre-activation functions. However, for deep neural networks fed by a single input, we have results even if the pre-activation is ReLU. When the network is shallow (i.e., there is exactly one hidden layer) the large and moderate principles hold for quite general pre-activations and in an infinite-dimensional setting. Joint work with Barbara Pacchiarotti (Università di Roma Tor Vergata) and Giovanni Luca Torrisi (IAC-CNR). 2. Jonathan Tam (Università di Verona) <https://sites.google.com/view/jonathanyytam/home> https://sites.google.com/view/jonathanyytam/home Title: Extended mean-field control: a finite-dimensional numerical approximation Date: February 21, 2025, at 15:30, room 1BC45 Abstract: We present a finite-dimensional numerical approximation for a class of extended mean field control problems. Our algorithm learns the value function on the whole Wasserstein domain, as opposed to a fixed initial condition. We leverage the approximation of the mean field problem by a finite-player cooperative optimization problem, due to the propagation of chaos, together with the usage of finite-dimensional solvers. This avoids the need to directly approximate functions on an infinite-dimensional domain, and allows for more efficient memory usage and faster computation times. Vi aspettiamo numerosi!

Seminars in Statistics at Collegio Carlo Alberto - Nial Friel (University College Dublin)
by Matteo Giordano 14 Feb '25

14 Feb '25

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.google.com/url?q=https://www.carloalberto.org/events/category/s…> Venerdì 21/02/2025, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ 12.00-13.00 Speaker: Nial Friel (University College Dublin) Title: The clustered Mallows model Abstract: Rankings represent preferences that arise from situations where assessors arrange items, for example, in decreasing order of utility. Orderings of the item set are permutations that reflect strict preferences. However, strict preference relations can be unrealistic for real data. In large item sets, assessors might prioritise certain items, rank others low, and express indifference towards the remaining. Rank aggregation may involve decisive judgments in some parts and ambiguity in others. In this talk, we extend the famous Mallows (Mallows, 1957) model (MM) to accommodate item indifference. Grouping similar items motivates the proposed Clustered Mallows Model (CMM), a MM counterpart for tied ranks with ties learned from the data. The CMM provides the flexibility to combine strictness and indifferences, describing rank collections as ordered clusters. Bayesian inference for the CMM is a doubly-intractable problem since the normalised model is unavailable. We overcome this with a version of the exchange algorithm (Murray et al.,2006) and provide a pseudo-likelihood approximation as a computationally cheaper alternative. Analysis of two real-world ranking datasets is presented, showcasing the practical application of the CMM and highlighting scenarios where it offers advantages over alternative models. ------------------------------------------------ Sarà possibile il seminario anche in streaming: chiunque volesse collegarsi è pregato di inviare una email entro *mercoledì 19/02/2025 * a matteo.giordano(a)unito.it <mailto:matteo.giordano@unito.it> Il webinar è organizzato dalla "de Castro" Statistics Initiative (www.carloalberto.org/stats <http://www.carloalberto.org/stats>) in collaborazione con il Collegio Carlo Alberto.
