Lunedì 20 maggio alle ore 14:30 in Aula di Consiglio si terrà il seminario dipartimentale della D.ssa Vittoria Silvestri che è recentemente risultata vincitrice della procedura valutativa di chiamata a RTD-A nel SSD MAT/06. Speaker: Vittoria Silvestri (Research Fellow in Mathematics, University of Cambridge) Titolo: Fluctuations and mixing for random growth models Abstract *Obtaining a rigorous understanding of the formation of complex patterns in nature is a long-standing problem, which has motivated the introduction of several probabilistic models in the Mathematics and Physics literature. In this talk I will present some of these models, both discrete and continuous, discussing asymptotic behavior, fluctuations and mixing and presenting results obtained in collaboration with L. Levine, J. Norris and A. Turner.* -- ************************************************* 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: Yosi Rinott su Privacy in data dissemination, differential privacy, and adaptivity,
by Antonio Pievatolo 16 May '19

16 May '19

Giovedì 23 maggio alle 14:30, presso il CNR-IMATI, in via A. Corti, 12, Milano, Aula A, si terrà il seguente seminario: Speaker: Yosi Rinott, The Hebrew University. Title: Privacy in data dissemination, differential privacy, and adaptivity. Abstract: I will demonstrate privacy issues that arise when an agency, for example ISTAT or a hospital, disseminates data such as a sample from some population or experimental results to the public or to other agencies. Various methods used by statisticians to assess the disclosure risk, and to decrease it will be briefly reviewed (e.g., Dalenius 1977). In general, such methods depend on scenarios regarding potential intruders, such as the intruder’s prior knowledge about the sample or the population. Differential Privacy (Dwork, McSherry, Nissim and Smith2006) is an approach that avoids the need to consider such scenarios, and guarantees a well-defined notion of privacy by adding noise to all released data. I will describe some basic results on differential privacy with some discussion of its application to the release of contingency tables (Dwork and Roth 2014, Rinott, O’Keefe, Shlomo, and Skinner 2018). Ongoing work on data analysis that takes the added noise into account will be discussed. An attempt to use ideas from differential privacy to control adaptive hypotheses testing or estimation will be described. Here, “adaptive” means choosing the hypotheses to be tested after peeking (snooping) at the data, which is a major problem in data mining, and probably explains in part why so many contradictory finding appear in medical journals. -- Dr Antonio Pievatolo IMATI-CNR http://www.imati.cnr.it/joomla/index.php/people?layout=edit&id=101 ph. +39 02 23699 520

Buongiorno vi riporto l'annuncio per un seminario congiunto di Fisica Matematica e Probabilità a Roma La Sapienza (v. sotto). Saluti Alessandra ************************************************************************************* Mercoledì 22 Maggio, ore 16:00, Aula di Consiglio Dipartimento di Matematica, Sapienza Università di Roma Speaker: Kirone Mallick (Institut de Physique Théorique, Parigi) Title: Continuous-time Quantum Walks Abstract: Quantum analogs of classical random walks have been defined in quantum information theory as a useful concept to implement algorithms. Due to interference effects, statistical properties of quantum walks can drastically differ from their classical counterparts, leading to much faster computations. In this talk, we shall discuss various statistical properties of continuous-time quantum walks on a lattice, such as: survival properties of quantum particles in the presence of traps (i.e. a quantum generalization of the Donsker-Varadhan stretched exponential law), the growth of a quantum population in the presence of a source, quantum return probabilities and Loschmidt echoes. ************************************************* 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 *************************************************

Colloquium di Luca Trevisan a Roma Tre il 12/06/19
by Pietro Caputo 13 May '19

COLLOQUIUM DI MATEMATICA Luca Trevisan U.C. Berkeley Titolo: Some simple distributed network processes Mercoledi' 12 Giugno 2019 ORE 16:00 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre Aula M3, edificio Aule - Largo San Leonardo Murialdo,1 Abstract We will describe network processes in which, at each step, each node communicates with its neighbors, or a random subset of neighbors, and updates its state according to the outcome of these communications. We will first talk about processes in which each node updates its state to be "more like" the state of the neighbors. In a complete communication network, such protocols provide a solution to the problem of reaching a consensus, and they do so in a way that is robust to adversarial interventions. In a communication network with a clustered structure, such protocols give a decentralized solution to the community detection problem. We will then discuss a protocol in which each node wants to choose a constant number of neighbors in such a way that the resulting constant-degree subnet of the communication network is an expander. This is done in a way to similar to how virtual networks are formed in peer-to-peer protocols. We show that if the original communication network is a dense expanders, the protocol will construct a constant-degree expander. (Based on joint work with Luca Becchetti, Andrea Clementi, Pasin Manurangsi, Emanuele Natale, Francesco Pasquale and Prasad Raghavendra.)
