Save the date: OWABI live from BayesComp - 19th June 1pm UK time
by Massimiliano Tamborrino 09 Jun '25

09 Jun '25

Dear all, the next OWABI seminar https://www.warwick.ac.uk/owabi, the last of this Season, is also going to be a special one, featuring two selected talks live from BayesComp https://bayescomp2025.sg/! The two talks are scheduled on Thursday the 19th June at 1pm UK time (note the different date and time!), given by * Filippo Pagani (University of Warwick): Approximate Bayesian Fusion * Maurizio Filippone (KAUST): GANs Secretly Perform Approximate Bayesian Model Selection with abstracts reported below. The talks will be streamed on Zoom at the link: https://monash.zoom.us/j/81050994376?pwd=aF52Ab2oUlNYPO251d4nDw0jXRemia.1<https://www.google.com/url?q=https%3A%2F%2Fmonash.zoom.us%2Fj%2F81050994376…> Meeting ID: 810 5099 4376 Passcode: 137607 1st OWABI Talk: 1-1.30pm Uk time Speaker: Filippo Pagani<https://filippopagani.github.io/> (University of Warwick) Title: Approximate Bayesian Fusion Abstract: Bayesian Fusion is a powerful approach that enables distributed inference while maintaining exactness. However, the approach is computationally expensive. In this work, we propose a novel method that incorporates numerical approximations to alleviate the most computationally expensive steps, thereby achieving substantial reductions in runtime. Our approach retains the flexibility to approximate the target posterior distribution to an arbitrary degree of accuracy, and is scalable with respect to both the size of the dataset and the number of computational cores. Our method offers a practical and efficient alternative for large-scale Bayesian inference in distributed environments. 2nd OWABI Talk: 1.30-2pm Uk time Speaker: Maurizio Filippone<https://www.kaust.edu.sa/en/study/faculty/maurizio-filippone> (KAUST) Title: Approximate Bayesian Fusion Abstract: Generative Adversarial Networks (GANs) are popular models achieving impressive performance in various generative modeling tasks. In this work, we aim at explaining the undeniable success of GANs by interpreting them as probabilistic generative models. In this view, GANs transform a distribution over latent variables Z into a distribution over inputs X through a function parameterized by a neural network, which is usually referred to as the generator. This probabilistic interpretation enables us to cast the GAN adversarial-style optimization as a proxy for marginal likelihood optimization. More specifically, it is possible to show that marginal likelihood maximization with respect to model parameters is equivalent to the minimization of the Kullback-Leibler (KL) divergence between the true data generating distribution and the one modeled by the GAN. By replacing the KL divergence with other divergences and integral probability metrics we obtain popular variants of GANs such as f-GANs, Wasserstein-GANs, and Maximum Mean Discrepancy (MMD)-GANs. This connection has profound implications because of the desirable properties associated with marginal likelihood optimization, such as (i) lack of overfitting, which explains the success of GANs, and (ii) allowing for model selection, which opens to the possibility of obtaining parsimonious generators through architecture search. We are looking forward to seeing you at the next OWABI seminar(s), best, Massimiliano on the behalf of the OWABI Organisers ------ Dr. Massimiliano Tamborrino Reader (Associate Professor) and WIHEA Fellow Department of Statistics University of Warwick https://warwick.ac.uk/tamborrino

by Sonia Mazzucchi 06 Jun '25

06 Jun '25

Seminari on-line del gruppo UMI - PRISMA (http://www.umi-prisma.polito.it/) I seminari PRISMA hanno un formato di "colloquium" per creare un'occasione di scambio e discussione con tutta la comunità dei probabilisti e statistici italiani. Ogni giornata comprende due relatori che tengono due seminari di 30 minuti strettamente connessi, per presentare alla comunità una prospettiva sul proprio ambito di ricerca. Da quest'anno le registrazioni dei seminari vengono pubblicate sul canale YouTube dell'UMI: https://youtube.com/playlist?list=PLmySpc-jrtAMq84VH71evyqPc1hl6eEQb Il prossimo appuntamento è per oggi *venerdì 6 giugno* 2025. I relatori saranno *Sara Mazzonetto* (Université de Lorraine) e *Paolo Pigato* (Università di Roma 2 “Tor Vergata”) che parleranno di: *Diffusioni a soglia e il ruolo del tempo locale* con il seguente orario: 16:00 Primo seminario 16:30 Pausa e discussione 16:45 Secondo seminario 17:15 Conclusione e discussione Trovate di seguito il riassunto. I seminari verranno trasmessi via Zoom al seguente link: https://unitn.zoom.us/j/82271416480 ID riunione: 822 7141 6480 Codice d’accesso: 130382 Vi aspettiamo numerosi! Alberto Chiarini e Sonia Mazzucchi %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Sara Mazzonetto (Université de Lorraine) e Paolo Pigato (Università di Roma 2 “Tor Vergata”) TITOLO: Diffusioni a soglia e il ruolo del tempo locale RIASSUNTO: Le diffusioni a soglia sono soluzioni di equazioni differenziali stocastiche i cui coefficienti cambiano in modo discontinuo a seconda della posizione del processo rispetto a delle barriere (soglie). Sono usate nella modellizzazione di vari fenomeni, in finanza/economia, ingegneria e altre scienze. In questo seminario, daremo un’introduzione a questi processi dal punto di vista matematico e parleremo delle loro applicazioni. Considereremo poi alcuni problemi di inferenza dei parametri, discutendo risultati asintotici sotto diverse ipotesi e sottolineando le difficoltà tecniche provenienti in particolare dalla connessione tra discontinuità, moto browniano skew e tempi locali. .%%%%%%%%%%%%%%%%%%%%%%%%%%%%

QFinLab Seminar - Marco Tolotti (Università Ca’ Foscari Venezia) - 9/6/2025, 12:15 @ Department of Mathematics, Politecnico di Milano
by Alessandro Calvia 05 Jun '25

05 Jun '25

Dear colleagues, you are all invited to participate in the following seminar organized by QFinLab - Department of Mathematics, Politecnico di Milano. Monday, 9 June 2025, 12.15-13.15 Seminar room, third floor, building 14, Via Bonardi 9, Milano (Leonardo Campus) Marco Tolotti (Università Ca’ Foscari Venezia) Title: Market Dynamics, Learning, and the Equity Premium Puzzle in an Agent-Based Model of Information Acquisition. Abstract: We analyze a financial market with a large number of investors who use an imitation-based learning mechanism to choose among various strategies that differ in the amount and quality of information they incorporate. Agents’ strategies evolve through a straightforward learning mechanism in which traders occasionally imitate more successful strategies adopted by peers they encounter. In this context, equilibrium is defined as a state where investors, on average, win half the time and lose in the remaining periods. Through an agent-based model, we show that at equilibrium, most investors rely on a limited number of strategies. In most scenarios, two strategies dominate: overly cautious traders, who hold little equity and capture the largest market share, and informed traders, who achieve higher average profits. Our model can help to justify the existence of an equity premium puzzle: in equilibrium, the higher mean profit of informed investors is associated with a median profit that is equal to that of more prudent or misinformed investors. All news can be found on the QFinLab webpage<https://www.qfinlab.polimi.it/seminars-and-meetings/>. The organizers: Michele Azzone and Alessandro Calvia.
