Probability Seminar in Sapienza
by Lorenzo Taggi 26 May '22

26 May '22

Dear All, next Tuesday Nicolas Forien (Sapienza Università di Roma) will give a seminar talk on particle systems and interacting random walks. Please find the title and the abstract below. Best regards, Lorenzo Taggi Tuesday 31st of May, 16.15, Dipartimento di Matematica Università Sapienza, Aula Consiglio *Title:* On the phase transition of activated random walks *Abstract:* The Activated Random Walk model consists of particles which perform independent random walks on a graph and fall asleep with a certain rate. Sleeping particles stop moving and are awaken when another particle arrives on the same site. The model on Z^d presents a phase transition: depending on the density of particles (initially all active) and on the sleep rate, either almost surely each particle eventually falls asleep forever (fixating phase), or almost surely no particle falls asleep forever (active phase). In this talk, I will present a joint work with Alexandre Gaudillière (arxiv.org/abs/2203.02476) showing the existence of an active phase on Z^2: for every positive initial density of particles, for a sufficiently low sleep rate, almost surely no particle falls asleep forever.

When: Wednesday May 25, 11.30am UK time Speaker: Harita Dellaporta<https://nam12.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwarwick.a…> (University of Warwick) Title: Robust Bayesian Inference for Simulator-based Models via the MMD Posterior Bootstrap Abstract: Simulator-based models are models for which the likelihood is intractable but simulation of synthetic data is possible. They are often used to describe complex real-world phenomena, and as such can often be misspecified in practice. In this talk, I will present a novel algorithm based on the posterior bootstrap and maximum mean discrepancy estimators. This leads to a highly-parallelisable Bayesian inference algorithm with strong robustness properties. This is demonstrated through an in-depth theoretical study which includes generalisation bounds and proofs of frequentist consistency and robustness of our posterior. The approach is then assessed on a range of examples including a g-and-k distribution and a toggle-switch model. ------ Dr. Massimiliano Tamborrino Assistant Professor Department of Statistics University of Warwick https://warwick.ac.uk/tamborrino<https://nam12.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwarwick.a…> -- You received this message because you are subscribed to the Google Groups "sis-news" group.

Seminar in Pisa: Enrico Malatesta

Dear Colleagues, we would like to invite you to the following seminar by Enrico Malatesta (Bocconi) to be held Wednesday, May 25th, at Dipartimento di Matematica in Pisa and online via Google Meets. The organizers, A. Agazzi and F. Grotto -------------------------------------------- Location: Sala Seminari, Dipartimento di Matematica, Pisa Google Meet Link: https://meet.google.com/gji-phwo-vbg Time: May 25th, 2022, 14:00-15:00 CET Speaker: Enrico Malatesta Title: Phase transitions in the landscape of solutions of overparametrized neural networks. Abstract: Current deep neural networks are nonlinear devices composed of a number of parameters that far exceed the number of data points. Understanding how these systems can fit the data almost perfectly through variants of gradient descent algorithms and achieve exceptional levels of prediction accuracy without overfitting are key conceptual challenges. In this talk I will show how common techniques used in machine learning (e.g. the choice of the activation function or the loss) deeply affect the loss landscape, tending to mild its roughness. Then we shed light on the role of overparameterization in non-convex neural networks. By analytically studying a non-convex model of random features, we identify a novel (non-equilibrium) phase transition, that we call “Local Entropy” transition, controlled by the degree of overparameterization. In non-convex models this transition is strictly different to the SAT/UNSAT threshold and it coincides with the appearance of highly entropic minima of the error loss function. Those minima, in turn, are found to be highly attractive to the learning algorithms currently used in deep learning.

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 27 Maggio 2022, alle ore 12.00, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Speaker: *Alexander Cox* (University of Bath) Title: *Binary branching processes with Moran type interactions* Abstract: In this talk, we will discuss the large population limit of a binary branching particle system with Moran type interactions: we introduce a new model where particles evolve, reproduce and die independently and, with a probability that may depend on the configuration of the whole system, the death of a particle may trigger the reproduction of another particle, while a branching event may trigger the death of another one. We study the occupation measure of the new model, explicitly relating it to the Feynman-Kac semigroup of the underlying Markov evolution and quantifying the L2 distance between their normalisations. This model extends the fixed size Moran-type interacting particle system discussed in Del Moral, Burdzy et al, and Villemonais, and we will indeed show that our model outperforms the latter when used to approximate a birth and death process. We discuss several other applications of our model including the neutron transport equation, Sequential Monte Carlo methods, and population size dynamics.

Dear Colleagues, it is my pleasure to bring to your attention the following two seminars in Quantitative Finance, organised by LTI@UniTO. The seminars can be attended online via Zoom at the links accessible via the buttons below. Best regards, Luca Regis -- Luca Regis Associate Professor Department of Economics and Statistics (ESOMAS) University of Torino sites.google.com/view/lucaregis <http://sites.google.com/view/lucaregis> Office: +39 011 670 6065 www.carloalberto.org/lti <http://www.carloalberto.org/lti> <#> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/dxQszhXdTYSeK8TgXWVwPdgch-yVozm308…> <#> LTI@UniTO and Fondazione Collegio Carlo Alberto are pleased to invite you to the following seminars: <#> *May 24, 2022 | 12:00-13:15* *Predicting Corporate Bond Returns: Merton Meets Machine Learning* *Amit Goyal (University of Lausanne)* <#> *Abstract.* We investigate the return predictability of corporate bonds using big data and machine learning. We find that machine learning models substantially improve the out-of-sample performance of stock and bond characteristics in predicting future bond returns. We also find a significant improvement in the performance of machine learning models when imposing a theoretically motivated economic structure from the Merton model, compared to the reduced-form approach without restrictions. Overall, our work highlights the importance of explicitly imposing the dependence between expected bond and stock returns via machine learning and Merton model when investigating expected bond returns. <#> *To attend in person, register here* <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/hfP4I4mUbx241x0z60A6739Y-00wYiECyk…> <#> *To attend online, join Zoom Meeting* <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/H7wKsG1vuV3OD31wQ_0E5gOGft1OURjriG…> <#> <#> *May 25, 2022 | 12:00 - 13:15* *JAQ of All Trades: Job Mismatch, Firm Productivity and Managerial Quality* *Marco Pagano (University of Naples Federico II)* <#> *Abstract.* Does the matching between workers and jobs help explain productivity differentials across firms? To address this question we develop a job-worker allocation quality measure JAQ by combining employer-employee administrative data with machine learning techniques. The proposed measure is positively and significantly associated with labor earnings over workers’ careers. At firm level, it features a robust positive correlation with firm productivity, and with managerial turnover leading to an improvement in the quality and experience of management. JAQ can be constructed for any employer-employee data including workers’ occupations, and used to explore the effect of corporate restructuring on workers’ allocation and careers. <#> *To attend in person, register here* <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/ykATFHYX2laIzxQ_xgRrxeAEz3ksTLnNgK…> <#> *To attend online, join Zoom Meeting* <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/Qu65mxHMOuyATkYSpHoaTbGG4jZwv1_-MW…> <#> <#> <#> <#> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/IfoXGKh5By8LrSGugLNRNVSXyH2VOsaTTd…> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/8usPEOcCcpYYly0bCauwMS_rfjHMGgHJVt…> <#> FONDAZIONE COLLEGIO CARLO ALBERTO Piazza Arbarello 8 - 10122 Torino, Italy phone: +39011 15630 800 segreteria(a)carloalberto.org - www.carloalberto.org Facebook <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/96qDEBjI389G7GVS3NgHy4QU5ODhiSBUXH…> Twitter <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/NblUBI8B5HmNemhQAOs_hH9Lb0xHqj4qYn…> LinkedIn <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/rMMfajyr067kRoDawTi2FFsw8dBZwyxWPW…> Instagram <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/0wIj1P36GYdj7O34J7nWI5VyNMMLDGzqBJ…> Youtube <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/-09AvrjEn7eE8yYbc-ZCF8ERm7rdddPHti…> <#> *INFORMATION UNDER THE NEW GENERAL DATA PROTECTION REGULATION (GDPR)* Your personal information has been gathered for the exclusive purpose of informing you about the Collegio's initiatives, considering our and your legitimate interest or your consent.

Dear All: Next Wednesday,*Anna Vidotto* (Università degli Studi di Napoli Federico II) will give a seminar talk on the Excursion Area of Time Dependent Spherical Random Fields, which will be held in person and online via Zoom. Details: * Date and time: Wednesday, May 25, 2022 at 14.30 pm * Place: room 2AB40 at the Department of Mathematics, University of Padua (Torre Archimede, via Trieste, 63, 35121 Padova) * Zoom link: please visit the webpage https://www.math.unipd.it/~bianchi/seminari/ * Title: On the Excursion Area of Time Dependent Spherical Random Fields * Abstract: In this talk, we consider isotropic and stationary real Gaussian time dependent random fields defined on the two dimensional unit sphere S^2 and we investigate the asymptotic behavior, as T tends to infinity , of the excursion area in S^2 × [0, T] at any threshold, covering both cases when the field exhibits short and long memory, that is, integrable and non-integrable temporal covariance. It turns out that the limiting distribution is not universal, depending both on the memory parameters and the threshold. The talk is based on a joint work with D. Marinucci and M. Rossi.

(PMS)^2 online talk: Sonia Mazzucchi
by margherita Zanella 18 May '22

18 May '22

Dear colleagues, we are happy to announce the following online talk: Speaker: Sonia Mazzucchi (Università di Trento) Title: Chernoff approximations for Feller semigroups in Riemannian manifolds. Abstract: In this talk I shall present the construction of Chernoff approximations for Feller semigroups in Riemannian manifolds of bounded geometry. This result provides approximations for solutions to initial-value problems for parabolic equations with variable coefficients on the manifold. It also yields the weak convergence of particular sequences of random walks on the manifolds to the diffusion processes associated with the elliptic generator. For parallelizable manifolds this result is applied in particular to the representation of the Brownian motion on the manifold as limit of the corresponding random walks.

OGGI: seminario su "Comparative gene finding on highly diverse chromosome alleles", Marina Axelson-Fisk 17 May
by Umberto Picchini 17 May '22

17 May '22

/[questo e' il nuovo annuncio di un seminario per //*oggi*//17 Maggio che era stato precedentemente cancellato]/ You are welcome to the next Statistics seminar at Dept of Mathematical Sciences at Chalmers and Göteborg University. On Tuesday May 17, Marina Axelson-Fisk <http://www.math.chalmers.se/~marinaa/> will talk of: ///"Comparative gene finding on highly diverse chromosome alleles" / * * marina axelson-fisk *About the speaker: *Marina Axelson-Fisk <http://www.math.chalmers.se/~marinaa/> is a Professor in Mathematical Statistics at Chalmers and University of Gothenburg. She works mainly within the field of Bioinformatics, with particular focus on stochastic models and algorithms for comparative genomics and cross-species gene finding. She is an associate member of the Linnaeus Centre for Marine Evolutionary Biology (CeMEB), where she is involved in the bioinformatics analysis of a number of newly sequenced Swedish coastal organisms. ** *Abstract:* With the new sequencing technologies, the number of novel genome sequences has exploded. At the same time the genome projects are hampered by the lack of homologies to the novel genome, making it difficult both to properly train genome analysis tools and to assess the results. Moreover, the faster and cheaper sequencing methods come with the cost of data quality, and sequencing and annotation errors that make it into the genome databases are propagated to new genomes, making annotation an even bigger challenge. Methods that can improve the data quality is desperately needed. Here we propose a novel use of comparative gene finding to improve the annotation in organisms with high nucleotide diversity. Comparative gene finding methods utilizes the contrast in sequence similarity between functional and non-functional regions of evolutionary related species. We show how this can be applied to chromosome pair sequences in diploid sequence data. We demonstrate the approach on the highly diverse sea orchid Balanus improvisus using SLAM, a cross-species gene finder that simultaneously annotates and aligns two homologous sequences using Generalized Pair Hidden Markov Models.* * *Feel free to spread this announcement in your network.* * * *Where*: room MVL14 or https://chalmers.zoom.us/j/62177902216 Password: 786749 ** **** *When*: Tuesday May 17 at 14.30-15.30*(Swedish time, UTC+2)*. ** -- _________________________________________________________ Umberto Picchini, Associate Professor, PhD, Docent https://umbertopicchini.github.io/ , twitter: @uPicchini

Seminars in Pisa: L. Andreis and G. Carigi
by Francesco Grotto 16 May '22

16 May '22

Dear Colleagues, we would like to invite you to the following seminars by Luisa Andreis (Università di Firenze) and Giulia Carigi (University of Reading) to be held Wednesday, May 18th, at Dipartimento di Matematica in Pisa and online via Google Meets. The organizers, A. Agazzi and F. Grotto -------------------------------------------- Location: Sala Seminari, Dipartimento di Matematica, Pisa Google Meet Link: https://meet.google.com/gji-phwo-vbg Time: May 18th, 2022, 14:00-15:00 CET Speaker: Luisa Andreis (UniFi) Title:Large deviations for coagulation processes: an approach via graphs Abstract: Interacting particle systems where particles interact via coagulation are of great interest for their various behaviours. In particular, interesting phenomena can occur, depending on the structure of the kernel which is giving a rate to each coagulation. Among these phenomena there is the famous phase transition that goes under the name of gelation, i.e. the appearance of one (or multiple) giant particle(s). Although fluid limits are known for the rescaled version of stochastic coagulation processes (convergence to the Smoluchowski coagulation equation and its modification), very few is known about large deviations and rare events in this framework. In this talk we will explore some connections of these processes with random graphs and how to use this connection to attack the problem of studying large deviations. This also allows a comparison with the phase transition in graphs, where a giant component appears. Some remarks about the possible generalization to coagulation kernels that depend on spatial position will be given. This is based on ongoing joint works with Wolfgang K ̈onig (WIAS and TU Berlin), Tejas Iyer (WIAS), Heide Langhammer (WIAS), Elena Magnanini (WIAS) and Robert Patterson (WIAS). Time: May 18th, 2022, 15:00-16:00 CET Speaker: Giulia Carigi (University of Reading) Title: Ergodic properties for a stochastic two-layer model of geophysical fluid dynamics Abstract: A two-layer quasi-geostrophic model for geophysical flows is studied, with the upper layer being perturbed by additive noise. This model is popular in the geosciences, for instance to study the effects of a stochastic wind forcing on the ocean. A rigorous mathematical analysis however meets with the challenge that the noise configuration is spatially degenerate as the stochastic forcing acts only on the top layer. Exponential convergence of solutions laws is established, implying a spectral gap of the associated Markov semigroup on a space of Hölder continuous functions. Moreover, response theory with respect to changes in the average wind forcing is established. Specifically, it is shown that the averages of a class of observables against the invariant measure are differentiable (linear response) and locally Hölder continuous (fractional response) as functions of a deterministic additive forcing. In doing so, a framework suitable to establish (linear and fractional) response for a class of nonlinear stochastic partial differential equations is provided.

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Mercoledi 18 Maggio 2022, alle ore 12.00, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Speaker: *Larry Goldstein* (University of Southern California) Title: *Relaxing Gaussian assumptions in high dimensional statistical procedures* Abstract: The assumption that high dimensional data is Gaussian is pervasive in many statistical procedures, due not only to its tail decay, but also to the level of analytic tractability this special distribution provides. We explore the relaxation of the Gaussian assumption in Single Index models and Shrinkage estimation using two tools that originate in Stein’s method: Stein kernels, and the zero bias transform. Taking this approach leads to measures of discrepancy from the Gaussian that arise naturally from the nature of the procedures considered, and result in performance bounds in contexts not restricted to the Gaussian. The resulting bounds are tight in the sense that they include an additional term that reﬂects the cost of deviation from the Gaussian, and vanish for the Gaussian, thus recovering this particular special case.

Seminario di Michele Aleandri alla Sapienza

12 May '22

Buongiorno sotto l'annuncio del seminario di Michele Aleandri alla Sapienza. Grazie Saluti Alessandra %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Mercoledì 18 Maggio, ore 16, Sala di Consiglio, Sapienza Università di Roma SPEAKER: Michele Aleandri (Sapienza Università di Roma) TITOLO: Opinion dynamics: conformist and nonconformist interacting agents ABSTRACT: We study two models of binary decisions in a connected network of interacting agents. Individual decisions are determined by social influence, coming from direct interactions with neighbours, and a group level pressure that accounts for social environment. We study the convergence of the mean field variables associated to the processes as the number of agents goes to infinity and we show that propagation of chaos occurs. In the first model, [2], we have a family of conformist or nonconformist agents that interact with each other. When the number of agents is large but fixed, we study the amount of time spent by the mean field variables associated with the process around the stable points of the macroscopic dynamics. In a nonconformist environment, there is a persistent disordered phase where no majority is formed: We show how in this case the introduction of a delay mechanism in the agent’s detection of the global average choice may drastically change this scenario, giving rise to a coordinated self sustained periodic behavior. In the second model, [1], the population is divided into two social groups, each one characterized by its attitude with respect to the other. Agents of the same group interact with each other, while the other group exerts on them a social influence, that may also be null or even negative. We focus in particular on models with Lotka-Volterra type interactions, i.e., models with conformist vs. nonconformist groups. For these models, although the microscopic system is driven a.s. to consensus within each group, a periodic behaviour arises in the macroscopic scale. In order to describe fluctuations between the limiting periodic orbits, we identify a slow variable in the microscopic system and, through an averaging principle, we find a diffusion which describes the macroscopic dynamics of such variable on a larger time scale.
