Buongiorno inoltro l'annuncio del OWPS di domani, che sarà focalizzato sul metodo di Stein (anche con applicazioni alla statistica). Saluti Alessandra ---------- Forwarded message --------- Da: One World Probability <ow.probability(a)gmail.com> Date: mer 17 mar 2021 alle ore 12:06 Subject: [owps] One World Probability Seminar Thursday March 18, 2021 To: <owps(a)lists.bath.ac.uk> Tomorrow's speakers in the One World Probability Seminar are (Note: all times are in UTC. *Due to time changes, you should check what that translates to in your location*) ------------------------------------------------ (14:00-15:00 UTC) Speaker: Yvik Swan (Université Libre de Bruxelles) Title: Stein’s density approach Abstract: Stein’s method is a collection of tools allowing to obtain explicit (non-asymptotic) bounds on discrepancies between probability distributions. The heart of the method is a so-called “Stein operator”, and it is the objective of this talk to present the basic theory behind these operators, and also cover some applications of the theory. After presenting the general theory (with a focus on Stein’s so-called density approach), we will give details on the 1-dimensional case, hereby connecting with classical topics such as Covariance and Poincaré inequalities. The material covered in the talk is closely related to work with Marie Ernst, Christophe Ley, Guillaume Mijoule and Gesine Reinert. (15:00-16:00 UTC) Speaker: Gesine Reinert (University of Oxford) Title: Stein’s method for multivariate continuous distributions and some statistical applications Abstract: Stein’s method can be viewed as employing an operator which action characterises a distribution uniquely, relating this operator to test functions through a Stein equation, and comparing distributions by taking expectations of this Stein equation. Using the density approach for Stein’s method, this talk will present a general framework for Stein’s method for multivariate continuous distributions. For any given nontrivial distribution this approach leads to an infinite collection of Stein characterisations which can be used to assess distributional distances. We shall apply this framework to compare posterior distributions which arise from the same model but using different priors. Using the notion of a weak Stein equation, bounds on distributional distances based on Lipschitz test functions are obtained if the distribution admits a Poincare’ constant. This result will be used to compare copulas. Finally, using the notion of a Stein kernel, we shall extend Stein’s shrinkage results and Stein’s Unbiased Risk Estimate (SURE) to non-Gaussian distributions. This talk is based on joint work with Max Fathi, Larry Goldstein, Adrien Saumard, and of course Yvik Swan. ------------------------------------------------ The zoom link will appear the day before on the OWPS website: https://www.owprobability.org/one-world-probability-seminar <https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.owpro…> It can also be directly accessed through the link below: https://uniroma1.zoom.us/j/81951703647?pwd=QUR4M0QraDFTZG5qY0VvVmVoS0pnZz09 <https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Funiroma1.…> Meeting ID: 819 5170 3647 Passcode: 614352 Please feel free to circulate this email.

Pisa Online Seminars - Michela Ottobre and Andrea Agazzi (Tuesday, Mar. 23 at 16:00 and 17:00)
by Giacomo Filippo Di Gesu 16 Mar '21

16 Mar '21

Dear colleagues, I would like to invite you to the following online seminar organized by the Probability group of the University of Pisa. The two talks will be accessible under the link Click here to join the meeting<https://teams.microsoft.com/l/meetup-join/19%3A17115d7f6ef44c5e91974362906c…> Best regards, Giacomo Tuesday, March 23, 16:00 Speaker: Michela Ottobre (Heriot-Watt University Edinburgh) Title: Uniform in time approximations of stochastic dynamics Abstract: Complicated models, for which a detailed analysis is too far out of reach, are routinely approximated via a variety of procedures; this is the case when we use multiscale methods, when we take many particle limits and obtained a simplified, coarse-grained dynamics, or, simply, when we use numerical methods. While approximating, we make an error which is small over small time-intervals but it typically compounds over longer time-horizons. Hence, in general, the approximation error grows in time so that the results of our ``predictions" are less reliable when we look at longer time-hormizons. However this is not necessarily the case and one may be able to find dynamics and corresponding approximation procedures for which the error remains bounded, uniformly in time. We will discuss a very general approach to understand when this is possible. I will show how the approach we take is very broad and show how it can be used for all of the approximation procedures mentioned above. This is based on a series of joint works with a number of people: L. Angeli, J. Barre', D. Crisan, P. Dobson, I. Souttar and E. Zatorska. Tuesday, March 23, 17:00 Speaker: Andrea Agazzi (Duke University) Title: Large deviations for stochastic models of chemical reaction networks Abstract: At the microscopic level, the dynamics of arbitrary networks of chemical reactions can be modeled as jump Markov processes whose sample paths converge, in the limit of large number of molecules, to the solutions of a set of algebraic ordinary differential equations. Fluctuations around these asymptotic trajectories and the corresponding phase transitions can in principle be studied through large deviations theory in path space, also called Wentzell-Freidlin (W-F) theory. However, the specific form of the jump rates for this family of processes does not satisfy the standard regularity assumptions imposed by such theory. This talk discusses how such conditions can be relaxed. In this talk, I will discuss sufficient stability and nondegeneracy conditions on the given family of Markov jump processes to obtain the desired large deviations estimates, and show how some of these conditions can be translated into structural ones, facilitating their verification for large chemical networks. ************************ Giacomo Di Gesù Dipartimento di Matematica Università di Pisa Largo Bruno Pontecorvo 5 56127 - Pisa, Italy giacomo.digesu(a)unipi.it<mailto:giacomo.digesu@unipi.it> https://sites.google.com/site/giacomodigesu/

Seminar announcement Thursday 25 - Reciprocity in a Preferential Attachment Network (prof. Tiandong Wang)
by Gianmarco Bet 16 Mar '21

16 Mar '21

Dear colleagues, On March Thursday 25 at 16:00, prof. Tiandong Wang (Texas A&M) will give a virtual seminar “in Florence”, to which you are all invited. You can find title and abstract below. Title: Reciprocity in a Preferential Attachment Network Abstract: Empirical studies show that online social networks have not only in- and out-degree distributions with Pareto-like tails, but also a high proportion of reciprocal edges. A classical directed preferential attachment (PA) model generates in- and out-degree distribution with power-law tails, but theoretical properties of the reciprocity feature in this model have not yet been studied. We derive the asymptotic results on the number of reciprocal edges between two fixed nodes, as well as the proportion of reciprocal edges in the entire PA network. We see that with certain choices of parameters, the proportion of reciprocal edges in a directed PA network is close to 0, which differs from the empirical observation. This points out one potential problem of fitting a classical PA model to a given network dataset with high reciprocity, and indicates alternative models need to be considered. The seminar will be on Zoom. You can find the information to join below. Topic: Tiandong Wang - Reciprocity in a Preferential Attachment Network Time: Mar 25, 2021 04:00 PM Rome https://us02web.zoom.us/j/82762436142?pwd=MW45SWN6NTBqV0VWbVJWREhESmtaZz09 Meeting ID: 827 6243 6142 Passcode: 897951 If you know of someone who might be interested and is not subscribed to the random mailing list, please do not hesitate to forward this announcement to them.

A sequence of 0-1 valued experiments on the population with outcomes X_1,..., X_n is called partially exchangeable if the only relevant information in the data is the number of 1's in each category. de Finetti's representation result guarantees that the distribution of the X's (for n<<N) is in bijection with measures pi^{(n)} on [0,1]^d. Natural problems -- such as understanding which of the subdivisions are truly meaningful and what is the effect of our initial belief pi^{(0)} -- can be addressed if one knows how to sample efficiently from these measures. In the absence of further information about the experiments, de Finetti suggests starting with a class of priors pi^{(0)}_{C,A} indexed by a d-dimensional network (measuring the relative differences among categories) and a positive parameter A (measuring the belief in complete exchangeability). in this talk I will analyze the performance of Gibbs sampling in approximating these measures in the almost exchangeable regime (A>>1). It will be shown that A^2 steps are necessary and sufficient to mix in a certain Wasserstein distance, with constants depending on few spectral parameters of the network C. This is based on joint work with Gerencsér. ------------------------------------------------ Il webinar è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats in collaborazione con il Collegio Carlo Alberto e rientra nel Complex Data Modeling Research Network midas.mat.uc.cl/network Cordiali saluti, Pierpaolo De Blasi --- University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/>

Buongiorno inoltro l'annuncio per il OWPS di domani, che sarà relazionato alla biologia. Saluti Alessandra ---------- Forwarded message --------- Da: One World Probability <ow.probability(a)gmail.com> Date: mer 10 mar 2021 alle ore 09:32 Subject: [owps] One World Probability Seminar Thursday March 11, 2021 To: <owps(a)lists.bath.ac.uk> Tomorrow's speakers in the One World Probability Seminar are (Note: all times are in UTC. *Due to time changes, you should check what that translates to in your location*) ------------------------------------------------ (14:00-15:00 UTC) Speaker: Viet Chi Tran (Université Gustave Eiffel) Title: Limit Theorems for Historical Particle Systems Abstract: To describe the evolving phylogenies of a birth and death process with trait structure and ecological interactions, we build a historical process inspired by works by Dawson and Perkins (1991 and 1995): it is a càdlàg process whose value at time t is a measure on lineages stopped at this time, i.e. paths describing the trait ancestries of the individuals living at time t. The dynamics may depend on past traits and allows interactions between individuals through their lineages. We establish the convergence of the individual-based birth-death process to a nonlinear historical superprocess, under the assumptions of large populations, small individuals and allometric demographies. The limit is described here by a macroscopic martingale problem. Because of the interactions, the branching property fails and we use fine couplings between our population and independent branching particles. This is a joint work with Sylvie Méléard. (15:00-16:00 UTC) Speaker: Sylvie Méléard (École Polytechnique, Paris) Title: Historical Processes and Dynamics of Phylogenies in a Population with Climate Change Abstract: We investigate in a simple model how the phylogenies of living individuals are shaped by the adaptation to a varying environment. In this model, the individuals are characterised by one-dimensional real traits (or positions). The stochastic individual-based birth-death process depends on a time-changing growth rate that shifts the optimal trait to the right and depends on a nonlinear logistic competition term. The macroscopic behaviour is described by a PDE that admits a unique positive stationary solution. We are interested here in the ancestral lineages of the living individuals in the stationary regime. The dynamic of these lineages is modelled by a historical process, approximatively close to a similar one with non-linearity frozen to its stationary value. We then use a many-to-one identity together with Feynman-Kac's formula and fine stochastic calculus to completely describe the limiting distribution, in large populations, of the path of an individual drawn at random at a given time. This path, in reversed time, is approximated by a simple Ornstein-Uhlenbeck. It shows how the lagged bulk of the present population stems from ancestors once optimal in trait but still in the tail of the trait distribution in which they lived. This talk is based on a joint work with Vincent Calvez, Benoit Henry and Viet Chi Tran. ------------------------------------------------ The zoom link will appear the day before on the OWPS website: https://www.owprobability.org/one-world-probability-seminar <https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.owpro…> It can also be directly accessed through the link below: https://uniroma1.zoom.us/j/86028841260?pwd=bUxyVUYzSjY5dDR4d3krb2lDTHZDQT09 <https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Funiroma1.…> Meeting-ID: 860 2884 1260 Passcode: 868252 Please feel free to circulate this email.

This year, we will be able to accept more applications than usual (about 10, compared to 7 usually). Bézout Master program is directed towards excellent students in mathematics or computer science (or both) from foreign institutions willing to pursue their studies in Université Paris-Est at the master's level. The laureates will receive about 1300 € per month over 11 months (pending approval of the University Executive Board) and will be proposed a room on the campus. Furthermore, the best students will then be invited to join the PhD program of the Doctoral School MSTIC (Mathematics, Sciences and Information and Communication Technology). A joint supervision with the student's national doctoral framework, leading to both PhD grades, is possible. The details of the program can be found here: http://bezout.univ-paris-est.fr/masters-scholarships/ <http://bezout.univ-paris-est.fr/masters-scholarships/> . From the same webpage, a link to the application form is available; the deadline will be May 21. On April 27 and 30, we plan to hold two online presentations of the Bézout master's program and scholarships, followed by a session of questions and answers; potential applicants should express their interest (without commitment to attend), so that we can send them the credentials for the meeting; see the webpage. A description of the activities of the Bézout Labex can be found in the leaflet at http://bezout.univ-paris-est.fr/wp-content/uploads/2020/11/bezout-leaflet.p….

Webinar Yi Yu @Bocconi
by Giacomo Zanella 09 Mar '21

09 Mar '21

We announce the following DEC Statistics webinar: Date: Thursday, March 11, h17:00 (Italy time) Speaker: Yi Yu (University of Warwick) Title: Functional Linear Regression with Mixed Predictors Abstract: We study a functional linear regression model that deals with functional responses and allows for both functional covariates and high-dimensional vector covariates. The proposed model is flexible and nests several functional regression models in the literature as special cases. Based on the theory of reproducing kernel Hilbert spaces (RKHS), we propose a penalized least squares estimator that can accommodate functional variables observed on discrete grids. Besides the conventional smoothness penalties, a group Lasso-type penalty is further imposed to induce sparsity in the high-dimensional vector predictors. We derive finite sample theoretical guarantees and show that the excess prediction risk of our estimator is minimax optimal. Furthermore, our analysis reveals an interesting phase transition phenomenon that the optimal excess risk is determined jointly by the smoothness and the sparsity of the functional regression coefficients. A novel efficient optimization algorithm based on iterative coordinate descent is devised to handle the smoothness and sparsity penalties simultaneously. Simulation studies and real data applications illustrate the promising performance of the proposed approach compared to the state-of-the-art methods in the literature. The webinar will be on zoom at: https://zoom.us/j/95651583993?pwd=ZnZjaGxvZWVLdGFSL0dGTk43eU9Idz09 Meeting ID: 956 5158 3993 Passcode: 568279 Kind regards, Giacomo Zanella

Fwd: [owps] One World Probability Seminar Thursday March 4, 2021

Buongiorno vi giro l'annuncio del OWPS di domani che sarà molto relazionato al trasporto ottimale. Grazie Alessandra ---------- Forwarded message --------- Da: One World Probability <ow.probability(a)gmail.com> Date: mer 3 mar 2021 alle ore 14:06 Subject: [owps] One World Probability Seminar Thursday March 4, 2021 To: <owps(a)lists.bath.ac.uk> Tomorrow's speakers in the One World Probability Seminar are (Note: all times are in UTC. *Due to time changes, you should check what that translates to in your location*) ------------------------------------------------ (14:00-15:00 UTC) Speaker: Matthias Erbar (Bielefeld University) Title: Optimal Transport and Gradient Flows in Discrete or Non-Local Settings Abstract: Optimal transport has become a powerful tool in the analysis of particle systems and the associated evolution equations. In particular the description as steepest descent or gradient flow in the Wasserstein distance gives insights on their long-time or limiting behavior. Yet many situations of interest fall outside the scope of the classical optimal transport theory. In the talk I will try to give an overview of some recent developments concerning the construction of different geometries on the space of probability measures tailored to capture the specific features of a given system. I will focus in particular on particles systems on discrete spaces and on the collisional dynamics in the Boltzmann equation. (15:00-16:00 UTC) Speaker: Jan Maas (IST Austria) Title: Optimal Transport: from Discrete to Continuous Abstract: Many stochastic systems can be viewed as gradient flow ('steepest descent') in the space of probability measures, where the driving functional is a relative entropy and the dissipation mechanism is described by a dynamical optimal transport problem. In this talk we focus on these optimal transport problems and describe recent work on the limit passage from discrete to continuous. Surprisingly, it turns out that discrete transport metrics may fail to converge to the expected limit, even when the associated gradient flows converge. We will illustrate this phenomenon in examples, discuss a geometric criterion for convergence, and present a recent homogenisation result. This talk is based on joint works with Matthias Erbar, Nicola Gigli, Peter Gladbach, Eva Kopfer, and Lorenzo Portinale. ------------------------------------------------ The zoom link will appear the day before on the OWPS website: https://www.owprobability.org/one-world-probability-seminar <https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.owpro…> It can also be directly accessed through the link below: https://uniroma1.zoom.us/j/85095168711?pwd=dGx2dnNySUZQNm40ZC9aWlJTaXZTZz09 <https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Funiroma1.…> Meeting-ID: 850 9516 8711 Passcode: 244220 Please feel free to circulate this email.

Statistics and Probability Seminars @University of Nottingham: Karthik Bharath (3pm Italian time)
by Fabrizio Leisen 03 Mar '21

03 Mar '21

Con preghiera di diffusione. *Italian time: 15:00* Cordiali Saluti, Fabrizio Dear All, the Statistics and Probability group at the University of Nottingham organize a series of internal seminars which will be available to anyone interested, even outside the University of Nottingham. Our next speaker is Karthik Bharath. Seminar date and time: *4**th* * of March at 2pm. * Below you can find the Abstract and Title. Furthermore, you can find the Teams link to join the seminar. Best Wishes, Fabrizio Leisen Professor of Statistics University of Nottingham School of Mathematical Sciences University Park, Nottingham, NG7 2RD, UK http://sites.google.com/site/fabrizioleisen/ You are cordially invited to the following seminar: Karthik Bharath <https://www.nottingham.ac.uk/mathematics/people/karthik.bharath> (Internal Seminar) ----> 4th of March *at 2pm* Title: Shape space and models for functional data Abstract: Statements such as “death rate curve needs to remain single peaked”; “we expect the second peak of infected cases to be smaller compared to the first”, are, unfortunately, all too familiar nowadays. They represent instances of informal descriptions of shapes of functions we can relate to readily, wherein the notion of shape relates exclusively to ‘y direction’ variation. To formalise this, in this talk, I will consider a group-theoretic description of the shape of a function as that which is left behind once ‘x direction’ variability is ignored: only the number and values of local extrema are relevant to describe its shape and not their timings. Accordingly, the shape of a function is shown to be uniquely encoded by a polynomial, and this connection allows us to study structural aspects of the shape space of functions. For statistical analysis of functional data (e.g., densely sampled multiple time series data) the upside to this perspective is that (i) a natural dimension reduction mechanism based on local extrema becomes available when analysing amplitudes that avoids the task of registering (or aligning) the data; and (ii) simple finite-dimensional generative shape models can be defined. On the other hand, geometry of the shape space is complicated, and this makes it difficult to compute descriptive statistics (e.g., average shape) and study models induced on the shape space from the original (simpler) function space. This is joint work with Ian Jermyn (Durham). __________________________________________________ Microsoft Teams meeting Join on your computer or mobile app Click here to join the meeting <https://teams.microsoft.com/l/meetup-join/19%3ameeting_YTYwODYyNDEtYThiZi00…> Learn more <https://aka.ms/JoinTeamsMeeting> | Meeting options <https://teams.microsoft.com/meetingOptions/?organizerId=ac48eccb-4345-40d8-…> -- Fabrizio Leisen Professor of Statistics University of Nottingham School of Mathematical Sciences University Park, Nottingham, NG7 2RD, UK http://sites.google.com/site/fabrizioleisen/
