Seminari Prisma 7 marzo
by Domenico Marinucci 28 Feb '22

28 Feb '22

Cari colleghi vi ricordo che lunedì prossimo 7 marzo alle ore 16 avranno luogo i prossimi due seminari nella serie Prisma; gli speaker sono Pietro Caputo e Vittoria Silvestri. I seminari avranno luogo come sempre sulla piattaforma teams; i dettagli per il collegamento e la lista completa dei seminari si possono trovare qui: http://www.umi-prisma.polito.it/webinars.html Qui sotto titoli ed abstract, grazie per l'attenzione, Domenico Marinucci ---------------------------------------------------------------------------- Speaker: Pietro Caputo, Roma III Title: Random walks on directed random networks Abstract: Exploration via random walks is often very useful for the analysis of directed networks. For instance, the walk's stationary distribution plays a prominent role in ranking systems and search algorithms. In this lecture, we present some recent progress in the analysis of random walks for a class of sparse directed networks generated by the so-called configuration model. We discuss various properties of the stationary distribution, including bulk behaviour and extremal values. We also consider the mixing time, that is the time needed to reach stationarity, and show that the walk typically displays a cutoff behaviour. Moreover, we discuss the asymptotic behaviour of the cover time, that is the expected time it takes the random walk to cover the whole network. Finally, we analyse the convergence to stationarity when the walk experiences regeneration events such as teleportation, as in the PageRank algorithm, or resampling of the underlying graph, as in a dynamically evolving network. ------------------------------------------------------------ Speaker: Vittoria Silvestri, Sapienza Title: Internal DLA on cylinder graphs: typical profiles and mixing. Abstract: Internal DLA is a mathematical model for the growth of a random cluster of particles according to the harmonic measure on the cluster boundary, seen from an internal point. Performing IDLA on cylinder graphs (i.e. graphs of the form GxZ) gives a Markov chain on the infinite space of particle configurations. We show that this chain is positive recurrent, and give a description of typical (i.e. stationary) configurations. We then analyse the mixing time of this chain. -- @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ Domenico Marinucci Dipartimento di Matematica Università di Roma Tor Vergata https://www.mat.uniroma2.it/~marinucc/ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

Inoltro ---------- Forwarded message --------- Da: Christian Horacio Olivera <colivera(a)unicamp.br> Date: mer 23 feb 2022 alle ore 15:43 Brazilian School of Probability/São Paulo School of advanced science on singular stochastic partial differential equations and their applications We are very excited to finally announce the EBP 2022/ São Paulo School of advanced science on singular stochastic partial differential equations and their applications. The São Paulo school is divided into two parts and will happen in the weeks of August 2 to August 13, 2022, at Campinas University. In the first week there will be two introductory mini courses by Paulo Ruffino (Campinas) and Weijun Xu (Beijing) (stochastic calculus and rough paths) that lay the foundations for the courses of the second week and are directed towards students and researchers with little to no experience in the field. The courses of the second week are held by Lorenzo Zambotti (Sorbonne) and Martin Hairer (Imperial College London). Here, newly developed theories and their latest developments in the field of singular SPDEs and related areas will be taught. The program will be complemented with several plenary talks, invited talks, a poster session and a visit to the LNLS laboratories, where the only particle accelerator of Latin America is located. The school will give full financial support for around 100 students and young researchers (50 from Brazil and 50 from abroad). To ask for financial support the registration deadline is April 15, 2022. More information under www.ime.unicamp.br/spas2022. The EBP 20022 will coincide with the second week of the São Paulo School. As in previous years, the EBP will consist of two mini courses, plenary talks, contributed talks and poster sessions, all presented in a relaxed atmosphere. This will be our first edition at IMECC-UNICAMP, which is home to one of Brazil's top ranked Mathematics departments. More information under www.ime.unicamp.br/bsp2022. To guarantee a safe event a big auditorium has been reserved that allows social distancing between participants. All required measures to prevent the spread of Covid 19 will be taken. We would be grateful if you could advertise these events among your colleagues. Best regards Christian Olivera

seminario: "Estimating the directing information and testing for causality", Maria Skoularidou, 1 Marzo
by Umberto Picchini 27 Feb '22

27 Feb '22

Caro gruppo Random, di sotto annuncio un seminario per il 1 Marzo. Saluti. *********************************************** You are welcome to the next Statistics seminar at Dept of Mathematical Sciences at Chalmers and Göteborg University. We are very glad to have, on Tuesday March 1, Maria Skoularidou <https://www.mrc-bsu.cam.ac.uk/people/in-alphabetical-order/n-to-s/maria-sko…> who will talk of: ///"Estimating the directing information and testing for causality" / * * *About the speaker: *Maria Skoularidou <https://www.mrc-bsu.cam.ac.uk/people/in-alphabetical-order/n-to-s/maria-sko…> is a PhD student at Cambridge University, UK. Her thesis is focused on probabilistic machine learning and, more precisely, towards using generative modelling in healthcare. Her fields of interest lie in the underpinnings, theory and methodology of machine intelligence, Bayesian inference, theoretical computer science and information theory. She is founder and chair of {Dis}Ability in AI <https://elesa.github.io/ability_in_AI/> and founder and secretary of Women in Data Science and Statistics (RSS special interest group). // //* * *Abstract: *The problem of estimating the directed information rate between two discrete processes { X n } and {Yn } via the plug-in (or maximum-likelihood) estimator is considered. When the joint process {(Xn,Yn)} is a Markov chain of a given memory length, the plug-in estimator is shown to be asymptotically Gaussian and to converge at the optimal rate O(1/√n) under appropriate conditions; this is the first estimator that has been shown to achieve this rate. An important connection is drawn between the problem of estimating the directed information rate and that of performing a hypothesis test for the presence of causal influence between the two processes. Under fairly general conditions, the null hypothesis, which corresponds to the absence of causal influence, is equivalent to the requirement that the directed information rate be equal to zero. In that case, a finer result is established, showing that the plug-in converges at the faster rate O (1/ n) and that it is asymptotically χ 2 -distributed. This is proved by showing that this estimator is equal to (a scalar multiple of) the classical likelihood ratio statistic for the above hypothesis test. Finally, it is noted that these results facilitate the design of an actual likelihood ratio test for the presence or absence of causal influence.* * *Feel free to spread this announcement in your network.* * * *Where*:https://chalmers.zoom.us/j/61015800942 Password: 697666 ** **** *When*: Tuesday 1 March at 14.15-15.15*(Swedish time)*. ** -- _________________________________________________________ Umberto Picchini, Associate Professor, PhD, Docent https://umbertopicchini.github.io/ , twitter: @uPicchini

We use it to study optimal government support in a lockdown that creates heterogeneous revenue losses to firms, which must borrow from banks. Firms’ increase in debt reduces their output due to moral hazard. Banks need safe collateral to raise funds. Without government support, aggregate risk constrains bank lending, amplifying output losses. Optimal support provides sufficient aggregate risk insurance, and is implemented with firm-specific transfers, fairly-priced guarantees on bank debt, and countercyclical firms’ taxation to achieve a fiscal surplus target. Our results shed light on suboptimality dimensions in the actual policy responses. <#> To attend in presence, register here https://forms.gle/vPYYEGBktf66zc4W6 <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/f9zEQSjy6xY7o19sfmiU7UwOhW9DQd5VBI…> To attend online, join zoom meeting https://us02web.zoom.us/j/88281857502?pwd=eW5GazNrYnFUUVR0cGg3RUlCM0NYUT09 <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/-IGT70kXO1-43Lgp7MtmZ2Fo3avErRm3RM…> Meeting ID: 882 8185 7502 Passcode: 161878 <#> <#> *March 2, 2022 | 16:00 - 17:15 @ WEBINAR* <#> *Schumpeterian Competition in a Lucas Economy* Daniel Andrei, /McGill University/ <#> *Abstract.* We model a rent-seeking game where agents experiment with a new technology and compete for claims to a consumption stream. We characterize how creative destruction affects risk, wealth, and asset prices. Competition not only imposes excessive disruption risk on existing assets and higher technological uncertainty, it also increases the wealth duration (the weighted-average maturity of the consumption stream). Because of hedging motives, a complementarity between wealth duration and technological uncertainty decreases systematic risk. If competition is sufficiently intense, a negative risk premium may arise. The model generates price paths consistent with boom-bust patterns and transient episodes of negative expected excess returns. We discuss the implications of competition for income inequality. <#> To attend online, Join Zoom Meeting https://us02web.zoom.us/j/82378901875?pwd=MVhPeTZGZktWNFk3RmdyMUltb3lDUT09 <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/tRYUAKB8XcDiTZ9YGCloGbosl3wS0nUBFI…> Meeting ID: 823 7890 1875 Passcode: 423048 <#> <#> <#> <#> <#> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/iaN__jlfz6z7ijnfLR9yi2AHyTYkufRgRm…> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/7J-M65ra_O8_zk55wtbsnjVbAlqEnu-eZ_…> <#> FONDAZIONE COLLEGIO CARLO ALBERTO Piazza Arbarello 8 - 10122 Torino, Italy phone: +390116705000 segreteria(a)carloalberto.org - www.carloalberto.org Facebook <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/Gny4_tfBFbYYjw5HiREGZ-3ih-MVeJe-HI…> Twitter <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/Ya696wYXuXevZmqUAl4AriMzYAAdxWQM75…> LinkedIn <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/wGq5ypAH5lBEZNV43pojp_3Bxd-QPNIYqf…> Instagram <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/Q-3bd3A33E3Uq--boYenIHuOmG53Ynvmlq…> Youtube <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/zolUnqcEQVaFklBL9NPBCULdSO9KrCqZol…> <#> *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.

by Daniele Cappelletti 23 Feb '22

23 Feb '22

Dear colleagues, I am happy to announce the following PhD course: The PhD course "Analysis and control of stochastic models of biomolecular interactions", taught by Dr. Ankit Gupta (Department of Biosystems Science and Engineering, ETH Zürich) will be hosted by Politecnico di Torino, Turin, Italy, in May 17-20, 2022. Attending in person is strongly recommended, but other options are available if necessary. To register and for any question, please write to daniele.cappelletti(a)polito.it. The course will deal with stochastic reaction network models, which are continuous time Markov chains commonly used to model biochemical dynamics within cells. Their theoretical and computational analysis is often quite challenging, and design of mathematical methods for their study is currently a very active research area. The goal of this course is to familiarize the students with a broad spectrum of these methods and illustrate them with several biological applications of current and lively interest in the research community. In particular, the following topics will be covered: 1. Finite State Projection methods 2. Moment Closure Schemes 3. Simulation approaches 4. Separation of Extrinsic and Intrinsic noise from biological data 5. Design of intracellular controllers in living cells Best regards, Daniele Cappelletti

(PMS)^2 online talk: Boualem Djehiche
by margherita Zanella 23 Feb '22

23 Feb '22

Dear colleagues, we are happy to announce the following online talk: Speaker: Boualem Djehiche (KTH, Stockholm) Title: Zero-sum mean-field Dynkin games. Abstract: I will review recent results on a class of zero-sum game problems of mean-field type which extend the classical zero-sum Dynkin game problems. The results I will highlight include sufficient conditions under which such a game admits a value and a saddle point and a characterization of the value of the game in terms of a specific class of doubly reflected backward stochastic differential equations (BSDEs) of mean-field type. Moreover, a corresponding system of weakly interacting values of zero-sum Dynkin games is introduced and is shown to converge to the value of the zero-sum mean-field Dynkin game. In particular, a propagation of chaos result is derived. This is a joint work with Roxana Dumistrescu. Date and time: Monday February 28, 17:30-18:30 (Rome time zone).

seminar: "Combined analysis of spatially misaligned data using Gaussian fields and the stochastic partial differential equation approach.", Paula Moraga 22 February
by Umberto Picchini 19 Feb '22

19 Feb '22

You are welcome to the next Statistics seminar at Dept of Mathematical Sciences at Chalmers and Göteborg University. We are very glad to have, on Tuesday February 22, Paula Moraga <https://www.paulamoraga.com/> (KAUST) who will talk of: ///"Combined analysis of spatially misaligned data using Gaussian fields and the stochastic partial differential equation approach."/ //** paula moraga *About the speaker: *Paula Moraga <https://www.paulamoraga.com/> is an Assistant Professor of Statistics at King Abdullah University of Science and Technology (KAUST) and the Principal Investigator of the GeoHealth research group. Her research focuses on the development of innovative statistical methods and computational tools for geospatial data analysis and health surveillance, and the impact of her work has directly informed strategic policy in reducing disease burden in several countries. She has developed modeling architectures to understand the geographic and temporal patterns and identify targets for intervention of diseases such as malaria in Africa and cancer in Australia, and has worked on the development of a number of R packages for Bayesian risk modeling, detection of disease clusters, and risk assessment of travel-related spread of disease. // //* * *Abstract: *Spatially misaligned data are becoming increasingly common due to advances in both data collection and management in a wide range of scientific disciplines including the epidemiological, ecological and environmental fields. Here, we present a Bayesian geostatistical model for fusion of data obtained at point and areal resolutions. The model assumes that underlying all observations there is a spatially continuous variable that can be modeled using a Gaussian random field process. The model is fitted using the integrated nested Laplace approximation (INLA) and the stochastic partial differential equation (SPDE) approaches. In the SPDE approach, a continuously indexed Gaussian random field is represented as a discretely indexed Gaussian Markov random field (GMRF) by means of a finite basis function defined on a triangulation of the region of study. In order to allow the combination of point and areal data, a new projection matrix for mapping the GMRF from the observation locations to the triangulation nodes is proposed which takes into account the types of data to be combined. The performance of the model is examined via simulation when it is fitted to point, areal, and point and areal data combined to predict several simulated surfaces that can appear in real settings. The model is also applied to predict the concentration of fine particulate matter (PM2.5) in Los Angeles and Ventura counties, USA, during 2011. The results show that the combination of point and areal data provides better predictions than if the method is applied to just one type of data, and this is consistent over both simulated and real data. We conclude the approach presented may be a helpful advance in the area of spatial statistics by providing a useful tool that is applicable in a wide range of situations where information at different spatial resolutions needs to be combined. *Feel free to spread this announcement in your network.* * * *Where*: https://chalmers.zoom.us/j/64709763394 Password: 920248 ** **** *When*: Tuesday 22 February at 14.15-15.15*(Swedish time)*. ** -- _________________________________________________________ Umberto Picchini, Associate Professor, PhD, Docent https://umbertopicchini.github.io/ , twitter: @uPicchini

Seminar José Figueroa Lopez in Verona, 23/2/22 at 12, Efficient Volatility Estimation for Lévy Processes with Jumps of Unbounded Variation
by Cecilia Mancini 16 Feb '22

16 Feb '22

José Figueroa Lopez Professor at the Washington University in St. Louis will give, both on site and on line, the SEMINAR Efficient Volatility Estimation for Lévy Processes with Jumps of Unbounded Variation Abstract. Statistical inference for stochastic processes based on high-frequency observations has been an active research area for more than a decade. One of the most well-known and widely studied problems is that of estimation of the quadratic variation of the continuous component of an Itô semimartingale with jumps. Several rate- and variance-efficient estimators have been proposed in the literature when the jump component is of bounded variation. However, to date, very few methods can deal with jumps of unbounded variation. By developing new high-order expansions of the truncated moments of a Lévy process, we construct a new rate- and variance-efficient estimator for a class of Lévy processes of unbounded variation, whose small jumps behave like those of a stable Lévy process with Blumenthal-Getoor index less than 8/5. The proposed method is based on a two-step debiasing procedure for the truncated realized quadratic variation of the process. Our Monte Carlo experiments indicate that the method outperforms other efficient alternatives in the literature in the setting covered by our theoretical framework. All interested people are warmly invited to participate Professor Figueroa-Lopez is visiting our department from February the 10th to March the 22nd, and from June the 15th to August the 15th For attendance via Zoom, please register at the following page, we will send you the meeting link: https://docs.google.com/forms/d/e/1FAIpQLSdJ6PccwEy8tSEngi0JMUKYEJ4yOHuuwur… Live attendance: the Department of Economics, via Cantarane 24, Vaona room.

The question has been heavily studied in streaming and related models of computation, for over four decades. In this talk I will present some recent advances: - Lower bounds for approximating quantiles in the deterministic comparison model, for additive error, which show that the best known algorithm is in fact optimal - Upper bounds for relative error epsilon-approximations of quantiles, which improves over previous results and exceed the best known lower bounds by only an O(log(1/e)3/2) factor. This covers joint work with Pavel Vesely, Justin Thaler, Edo Liberty and Zohar Karnin. ------------------------------------------------ Sarà possibile seguire il seminario anche in streaming: Join Zoom Meeting <https://us02web.zoom.us/j/88206863118?pwd=cmlHYzBXbW9NZ2JVYmtDbDNqNnFydz09> Meeting ID: 882 0686 3118 Passcode: 757710 Il seminario è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats Cordiali saluti, Pierpaolo De Blasi -- Pierpaolo De Blasi University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/>
