SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 18 Novembre 2022, alle ore 11.00, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Speaker: *Rao Vinayak* (Purdue University USA) Title: *Differential Privacy and Bayesian Computation: Two Vignettes* Abstract: Differential privacy (DP) protects privacy by introducing additional randomness into a recorded dataset. It comes with strong theoretical guarantees, and has become a state-of-the-art framework for privacy protection. In this talk, we consider two complementary challenges raised by DP. In the first part, we recognize that implementing DP mechanisms require sampling algorithms like MCMC or rejection sampling. In these instances, the algorithm runtime itself can leak privacy, so that practical implementations fail to maintain the original theoretical guarantees. To address this, we propose modifications to rejection and adaptive rejection sampling algorithms, with varying assumptions, to protect against timing attacks. In the second part, we focus on a more traditional statistics problem related to differential privacy: given access to only the privatized data, how to perform valid statistical inference on parameters underlying the confidential data. Here, the likelihood function of the privatized data requires integrating over the large space of confidential databases and is typically intractable, resulting, in Bayesian settings, in a posterior distribution that is doubly intractable. We propose a generic MCMC framework which is applicable to a wide range of statistical models and privacy mechanisms. Our MCMC algorithm is a simple wrapper that extends MCMC algorithms for the unobserved confidential data to settings where the data is privatized. Our approach translates privacy guarantees of the DP mechanism into mixing properties of the MCMC algorithm, while maintaining the same order of computational cost as the algorithm for non privatized data. We illustrate the efficacy and applicability of both our ideas on several examples. ------------------------------------------------ Sarà possibile seguire il seminario anche in streaming: Join Zoom Meeting <https://us02web.zoom.us/j/87612328974?pwd=OFZnMGxrWll6ZE9uVHdjQTkzYUN3Zz09> Il seminario è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats -- Pierpaolo De Blasi University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/>

The ABS school is back! Bayesian Causal Inference in Firenze (June 12-16, 2023)
by Elisa Varini 11 Nov '22

11 Nov '22

Dear all, we are glad to inform you that the Applied Bayesian Statistics school is back! ABS23 will be held in Firenze on June, 12-16, 2023. The school is organised by CNR IMATI (Institute of Applied Mathematics and Information Technologies at the Italian National Research Council in Milano), this year in cooperation with the Florence Center for Data Science and the Department of Statistics, Computer Science and Applications at the University of Firenze. The topic will be BAYESIAN CAUSAL INFERENCE. The lecturer will be FAN LI (Duke University, https://scholars.duke.edu/person/fli) with the support by researchers at the University of Firenze. If interested, you can register on the school website: http://www.mi.imati.cnr.it/conferences/abs23/ REGISTRATION is now open but payments will be possible (by bank transfer or credit card) only after January, 30, 2023. If you are interested in the school but unwilling to register for the moment, please send an email to abs23(a)mi.imati.cnr.it and we will send you updates and reminders. As in the past (since 2004), there will be a combination of theoretical and practical sessions, along with presentations by participants about their work (past, current and future) related to the topic of the school. OUTLINE: The aim of this course is to introduce the fundamental concepts and the state-of-the-art methods for causal inference under the potential outcomes framework, with an emphasis on the Bayesian inferential paradigm. Topics will cover randomized experiments, common methods for observational studies, such as propensity score, matching, weighting and doubly-robust estimation, heterogeneous treatment effects, sensitivity analysis, instrumental variables, principal stratification, panel data methods, and longitudinal treatments. Recent advances related to high dimensional analysis and machine learning will be naturally incorporated into the discussion. All methods will be illustrated via real world case studies. We hope you will be interested in the school and we would like to meet you in Firenze next year. We invite you also to share the information with people potentially interested. Best regards Elisa Varini and Fabrizio Ruggeri Executive Director and Director of ABS23

Seminar: Riccardo Maffucci at Tor Vergata
by mic sal 09 Nov '22

09 Nov '22

Dear all, next Thursday, May 5th, Riccardo Maffucci (EPFL) will give a seminar about "Distribution of nodal intersections for random waves". Abstract: This work is in collaboration with Maurizia Rossi. Random waves are Gaussian Laplacian eigenfunctions on the 3D torus. We investigate the length of intersection between the zero (nodal) set, and a fixed surface. Expectation, and variance in a general scenario are prior work. In the generic setting we prove a CLT. We will discuss (smaller order) variance and (non-Gaussian) limiting distribution in the case of ’static’ surfaces (e.g. sphere). Under a certain assumption, there is asymptotic full correlation between intersection length and nodal area. The seminar will take place in Aula De Blasi, Università Tor Vergata, at 16h00. We encourage in-person partecipation, but should you unable to come here is the link to the event on Teams: https://teams.microsoft.com/l/meetup-join/19%3arfsL73KX-fw86y1YnXq2nk5VnZFw… The seminar is part of the Excellence Project Math@TOV.

avviso di seminario

08 Nov '22

Università di Napoli Federico II Dipartimento di Matematica e Applicazioni Avviso di Seminario Il giorno 15 novembre p.v. alle ore 16 nell'aula G al III livello, la Dott.ssa Fatemeh Hooti, assegnista di ricerca presso il Dipartimento di Matematica e applicazioni, terrà un seminario dal titolo "Optimal Extended Warranty Length With Limited Number of Repairs in The Warranty Period". Abstract: Due to the advances in the technology of complex industrial systems, the consumers of these products are always worried about the costs of purchasing and maintenance of them. Manufacturers also want to increase the number of customers for their products and profit from sales. However, the reliability of engineering systems can be affected by several factors, so the occurrence of failure and the need to repair and maintain these products after their production is inevitable. In this case, the discussion of the warranty of the manufactured products plays an important role in assuring the consumers and also reducing the damages to producers and customers. The policies introduced for the warranty of engineering systems are divided into two categories one-dimensional and two-dimensional warranty based on the number of variables that are aimed at optimizing the fixed and random costs of the project. Also, so far, several cost functions have been considered to check and reduce these costs. In the talk, a policy plan is proposed for the warranty length of a repairable system which consists of a number of minimal repairs and duration of service?. ?For this purpose?, ?two total expected costs of the manufacturer are considered as the objective of the optimization model, and the conditions for finding unique optimal solutions are investigated?.
