Seminario di Probabilità - Roma La Sapienza
by Faggionato, Alessandra 05 May '22

05 May '22

Buongiorno, il Prof. Sebastian Andres terrà un seminario in Sala di Consiglio al Dipartimento di Matematica dell' Università La Sapienza , Lunedì 9 Maggio alle ore 16:00 (sotto i dettagli). Grazie dell'attenzione Saluti Alessandra %%%%%%%%%%%%%%%%%%%%%%%%%% Time: Monday 9 May 2022, at 16:00 Rome: Sala di Consiglio, Department of Mathematics, Sapienza University of Rome Speaker: Sebastian Andres (Manchester University) Title: First passage percolation with long-range correlations Abstract: In this talk we consider first passage percolation (FPP) with passage times generated by a general class of models with long-range correlations, including discrete Gaussian free fields as a prominent example. We will discuss conditions under which the associated time constant is positive and the FPP distance is comparable to the Euclidean distance. We will also present two applications to random conductance models (RCM) with possibly unbounded and strongly correlated conductances, namely a Gaussian heat kernel upper bound for RCMs with a general class of speed measures, and an exponential decay estimate for the Green function of RCMs with random killing measures. This talk is based on a joined work with Alexis Prévost (Cambridge). -- ************************************************* Prof. Alessandra Faggionato http://www1.mat.uniroma1.it/~faggionato/ Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome Office 5, Phone (0039) 06 49913252 *************************************************

seminario G.Ascione - Sapienza 11 maggio
by Luisa Beghin 05 May '22

05 May '22

Buongiorno, vorrei segnalare il seguente seminario: *Mercoledì 11 maggio 2022* Ore 14:30, Aula 34 (quarto piano), Dipartimento di Scienze Statistiche, Sapienza Università di Roma e online al seguente link meet.google.com/dwz-gvib-uoj *Titolo:* A sojourn-based approach to discrete-time semi-Markov decision processes *Speaker*: Giacomo Ascione (Scuola Superiore Meridionale) *Abstract:* Up to now, there is an extensive literature on stepped continuous-time semi-Markov decision processes. Such models generalize the classical continuous-time Markov chain decision processes by allowing for different distributions of interevent times. However, in such models, the decision is always taken in a change of state, so that it influences a priori the distribution of the inter-event times. For such a reason, these models do not allow for decision depending on intermediate observations of the system. In this talk we address the problem of intermediate observations by modelling the system as a finite horizon discrete-time semi-Markov process, thus assuming discrete observations of the system, and allowing possible decisions at each time step. To do this, we first provide an alternative characterization of discrete-time semi-Markov processes in terms of a bivariate Markov chain, involving both the state and the sojourn time of the process. Once this is done, one can use the dynamic programming principle to exploit optimal policies for the discrete-time semi-Markov decision process by resorting to the bivariate Markov formulation. With this approach we are able to exhibit the Bellman’s equation for both the value and the quality function. The latter is then used to develop a model-free reinforcement learning algorithm based on Watkins and Dayan’s Qlearning algorithm, together with a first naive attempt towards a deep reinforcement learning one. Two exploratory toy examples are provided. This is based on a joint work with Salvatore Cuomo from Università degli Studi di Napoli Federico II. Cordiali saluti.

(PMS)^2 online talk: Michele Salvi - May 9, 17:30
by Maurizia Rossi 04 May '22

04 May '22

Dear colleagues, We are happy to announce the following online talk: Speaker: *Michele Salvi* (Università di Roma "Tor Vergata") Title: *Scale-free percolation mixing time.* Abstract: Scale-free percolation is a spatial inhomogeneous random graph model which features three fundamental properties that are often present in real-world networks: (1) Scale-free: the degree of the nodes follows a power law; (2) Small-world: two far-away nodes have typically a small graph distance; (3) Positive clustering coefficient: two nodes with a common neighbour have a good chance to be linked. We study the mixing time of the simple random walk on this structure in one dimension and depict a rich phase diagram in the parameters of the model. In particular, we prove that the presence of hubs can speed up the mixing of the chain. Joint work with Alessandra Cipriani (UCL). *Date and time:* Monday May 9, 17:30-18:30 (Rome time zone) *Zoom link:* https://us02web.zoom.us/j/6815552946 This talk is part of the *(PMS)^2*: *Pavia-Milano Seminar series on Probability and Mathematical Statistics* organized jointly by the universities Milano-Bicocca, Pavia, Milano-Politecnico and Milano-Statale. Participation is free and welcome! Best regards The organizers (Mario Maurelli, Carlo Orrieri, Maurizia Rossi, Margherita Zanella) -- Maurizia Rossi Dipartimento di Matematica e Applicazioni Università degli Studi di Milano-Bicocca https://mauriziarossi.wordpress.com

Manifestazioni di interesse RTD-B MAT/06 a Parma
by Francesco Morandin 03 May '22

03 May '22

Salve a tutti, vorrei raccogliere manifestazioni di interesse qualificate per una posizione RTD B in probabilità (MAT/06) che potrebbe essere bandita nel prossimo futuro presso il Dipartimento di Scienze Matematiche, Fisiche e Informatiche di Parma. Gli interessati sono incoraggiati a contattarmi, anche per informazioni e chiarimenti. -- Francesco Morandin -- frmor.net Department of Mathematical, Physical and Computer Sciences Parma University -- sfmi.unipr.it To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination: he may be able to say what the experiment died of.
