Seminario Antonio Lerario Roma Tor Vergata
by Anna Vidotto 06 Dec '19

06 Dec '19

I would like to announce the following talk that will be held on Thursday December 12th 2019, at 4:30 PM, in Aula Dal Passo of the Department of Mathematics, University of Rome Tor Vergata. Speaker: Antonio Lerario (SISSA Trieste) Title: Low-degree approximation of real singularities Abstract: In this talk I will discuss some recent results that allow to approximate a real singularity given by polynomial equations of degree $d$ (e.g. the zero set of a polynomial, or the number of its critical points of a given Morse index) with a singularity which is diffeomorphic to the original one, but it is given by polynomials of degree $O(d^{1/2}log d)$. The approximation procedure is constructive (in the sense that one can read the approximating polynomial from a linear projection of the given one) and quantitative (in the sense that the approximating procedure will hold for a subset of the space of polynomials with measure increasing very quickly to full measure as the degree goes to infinity). This is based on a combination of joint works with P. Breiding, D. N. Diatta and H. Keneshlou. — This talk is part of the activity of the MIUR Excellence Department Project CUP E83C18000100006 — —————— Anna Vidotto PostDoc Researcher Dipartimento di Matematica Università degli Studi di Roma Tor Vergata https://sites.google.com/view/annavidotto

Guido Consonni and Fabrizio Ruggeri ABS20 Directors Raffaele Argiento and Antonio Pievatolo ABS20 Executive Directors ------------------------------------------------------------------------ ******************************* * ABS20 * ******************************* Applied Bayesian Statistics School BAYESIAN CAUSAL INFERENCE Florence Center for Data Science, University of Florence Florence, Italy 8-12 June, 2020 Lecturer: Prof. Fan Li (Department of Statistical Science, Duke University, Durham, NC, USA) https://stat.duke.edu/people/fan-li The conference webpage is >>> http://www.mi.imati.cnr.it/conferences/abs20/index.html <<< Registration is now open to reserve a place (but payments are possible only from early January). Please note that the conference room allows only for a very limited number of participants. COURSE OUTLINE The aim of this course is to introduce the fundamental concepts and state-of-art methods for causal inference under the potential outcome framework. The lectures will be organized by the treatment assignment mechanisms. Topics will cover randomized experiments, observational studies with ignorable assignment mechanisms, natural experiments, sequential ignorable longitudinal treatments. Recent advances related to machine learning and more complex situations such as spatial-temporal treatments and interference will also be discussed. All methods will be illustrated via real case studies in health studies, economics and biology. Though the causal framework and most of the methods are independent of the inferential paradigm, an emphasis will be put on the Bayesian paradigm for inference. TENTATIVE PROGRAM See the daily program on the website. PRACTICAL INFORMATION The school will replicate the successful format of the previous years, and will feature lectures and practical sessions (run by a junior researcher), as well as participants' talks. It will start on Monday after lunch and end on Friday before lunch; Wednesday afternoon is free. Info on accommodation will appear soon on the website.

Seminario di Tyler Helmuth (Bristol) a Roma Tre, 12-12-2019
by Alexandre Stauffer 03 Dec '19

03 Dec '19

SEMINARIO Probabilita' Tyler Helmuth (University of Bristol) Titolo: Random spanning forests and hyperbolic symmetry Giovedi' 12 Dicembre 2019 ORE 10:00 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre Largo San Leonardo Murialdo,1 - Pal.C - Aula 211 Abstract The arboreal gas is a probability measure that arises from conditioning the random subgraph given by Bernoulli(p) bond percolation to be a spanning forest, i.e., to contain no cycles. This conditioning makes sense on any finite graph G, and specializes to the uniform measure on spanning forests when p = 1/2. One is naturally lead to ask about the percolative properties of the arboreal gas, and this turns out to be a surprisingly rich question. I will discuss some results and conjectures about the arboreal gas, most of which are based on important relations between the arboreal gas and spin systems with hyperbolic symmetry. Based on joint work in progress with Roland Bauerschmidt, Nick Crawford, and Andrew Swan.

Economists For Future (fwd)
by Tiziano Vargiolu 02 Dec '19

02 Dec '19

Per completezza: c'e' una cosa molto importante che non viene detta sotto, ma nella procedura di firma si', ed e' questa: IMPORTANT: This open letter is open to everyone to sign, not just economists! Cordiali saluti a tutti ---------- Forwarded message ---------- Date: Mon, 02 Dec 2019 13:16:12 +0000 From: Luisa Jentsch <noreply(a)econ4future.org> Reply-To: info(a)econ4future.org To: Tiziano <vargiolu(a)math.unipd.it> Subject: Economists For Future Dear Tiziano, I write to introduce you to Economists for Future?s open letter that is calling on the economics community to raise its game and devise a more impactful contribution to tackling climate change. Economists for Future is an international student-led organisation with the aim to put pressure on the economics community to treat climate change like the emergency it is. While many economists have shown great academic leadership on this issue, the overall contribution from the community has not been commensurate with the magnitude of the problem. The shortage of climate change related articles in top journals is one such demonstration. For example, the most-cited journal in our discipline has never published an article on climate change [https://lists.econ4future.org/links/iJ9AW4JXP/PfQP6QyMO/aMbvBGRdzdg/YJmX2li…] As the next generation of economists, as young people who will live through the most severe climate effects and as individuals with a deep belief in the power of good economics to make the world a better place, we feel an acute pressure to ?do more? that we are hoping you will share. We think economists have both a responsibility and an enormous opportunity to have an even greater contribution to help tackle this emergency. The open letter (attempts to) make the case for economists seizing this opportunity to provide the intellectual framework that enables a rapid decarbonisation that is coupled with a great leap in human progress. We would like to invite you to support this initiative by signing the letter, which you can do by filling out the form on our website. [https://lists.econ4future.org/links/iJ9AW4JXP/PfQP6QyMO/aMbvBGRdzdg/K8_4G0o…] And, if you agree with it, we would kindly ask you to share your support among your social and academic networks. If you have any questions about our initiative or the letter, we would love to hear from you ? at the end of the day, we are curious students that desire more from the discipline we want to dedicate our lives to.

Seminario Prof. Claudio Macci

Il Prof. Claudio MACCI dell'Università di Roma Tor Vergata mercoledì 4 dicembre 2019 alle ore 16 nell'Aula E al III livello del Dipartimento di Matematica e Applicazioni dell'Università degli Studi di Napoli Federico II terrà un seminario dal titolo: Large deviations for risk measures in finite mixture models ABSTRACT Due to their heterogeneity, insurance risks can be properly described as a mixture of different fixed models, where the weights assigned to each model may be estimated empirically from a sample of available data. If a risk measure is evaluated on the estimated mixture instead of the (unknown) true one, then it is important to investigate the committed error. In this paper we study the asymptotic behaviour of estimated risk measures, as the data sample size tends to infinity, in the fashion of large deviations. We obtain large deviation results by applying the contraction principle, and the rate functions are given by a suitable variational formula; explicit expressions are available for mixtures of two models. Finally, our results are applied to the most common risk measures, namely the quantiles, the expected shortfall and the shortfall risk measure. Joint work with Valeria Bignozzi and Lea Petrella.

Avviso di Seminario, università di Trento Stochastic homogenization in amorphous media and applications to interacting particle systems and random resistor networks Giovedì 5 dicembre 2019 Luogo: Polo Ferrari 1, via Sommarive, 5 - Povo (TN) - Aula A221 Ore: 16:00 Relatore: Alessandra Faggionato (Università La Sapienza, Roma) Abstract: We consider random walks on marked simple point processes with symmetric jump rates and unbounded jump range. Examples are given by simple random walks on Delaunay triangulations or Mott variable range hopping in doped semiconductors. We present homogenization results for the associated Markov generators. As a first application, we obtain the hydrodynamic limit of the exclusion process given by multiple random walks as above, with hard–core interaction. As a second application, we derive a limit theorem for the effective conductivity of some classes of random resistor networks. This result together with a percolation-type analysis allows to derive the low temperature scaling behavior of conductivity in some classes of strongly disordered media.

Seminar Berthet @Bocconi
by Giacomo Zanella 25 Nov '19

25 Nov '19

We announce the following DEC Statistics seminar: Thursday, November 28 12:30 Meeting room 3-e4-sr03, Bocconi University, Via Roentgen 1, 3rd floor Quentin Berthet (Google Research) Title: Optimal transport methods in statistics and machine learning: theory and applications Abstract: Optimal transport is one of the foundational problems of optimization, and a very important topic in analysis. It asks how one can transport mass with a given measure to have another measure, with minimal global transport cost. The associated Wasserstein distance is a useful statistical tool to compare distributions, taking into account geometric properties of the data. In this presentation, I will talk about two recent projects on this topic. In the first one, we propose a novel approach for unsupervised embedding alignment, and show applications to natural language processing. It is based on a new approach for Wasserstein loss minimization (joint work with E. Grave and A. Joulin). In the second one, we provide new methods and guarantees for estimation of distributions with smooth densities, in the Wasserstein distance. We show that these tools, inspired by techniques in nonparametric statistics, yield information-theoretic optimal results. We also develop ideas to handle our proposed estimators in a computationally efficient manner, and explore some of the associated computational trade-offs (joint work with J. Weed). Kind regards, Giacomo Zanella The DEC statistics seminars schedule is available at http://www.unibocconi.eu/statseminar Please note: if you are a guest and you do not have a Bocconi ID Card to access to the Bocconi Buildings, please communicate your participation by sending an email to elisa.picassi(a)unibocconi.it

We proceed by providing some interesting applications of this new idea which includes the characterization of ergodic constants and hypercontractivity estimates for non-self-adjoint semigroups. We illustrate these results by presenting several examples that have emerged from the recent literature: discrete-to-continuous interacting particle models, degenerate hypoelliptic Ornstein-Uhlenbeck processes, and diffusion-to-jump Jacobi processes. This talk is based on a joint a work with L. Miclo (IMT Toulouse). Tutti gli interessati sono invitati a partecipare.

Seminario RYDER

STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO Venerdì 29 Novembre 2019, alle ore 12:00, presso il nuovo edificio del Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Robin RYDER (Université Paris Dauphine) A BAYESIAN NON-PARAMETRIC METHODOLOGY FOR INFERRING GRAMMAR COMPLEXITY Based on a set of strings from a language, we wish to infer the complexity of the underlying grammar. To this end, we develop a methodology to choose between two classes of formal grammars in the Chomsky hierarchy: simple regular grammars and more complex context-free grammars. To do so, we introduce a probabilistic context-free grammar model in the form of a Hierarchical Dirichlet Process over rules expressed in Greibach Normal Form. In comparison to other representations, this has the advantage of nesting the regular class within the context-free class. We consider model comparison both by exploiting this nesting, and with Bayes’ factors. The model is fit using a Sequential Monte Carlo method, implemented in the Birch probabilistic programming language. We apply this methodology to data collected from primates, for which the complexity of the grammar is a key question. (joint work with L. Murray, J. Rousseau and A. Thin) ------------------------------------------------ Tutti gli interessati sono invitati a partecipare. Il seminario è organizzato dalla "de Castro" Statistics Initiative (www.carloalberto.org/stats <http://www.carloalberto.org/stats>) in collaborazione con il Collegio Carlo Alberto.
