SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 17 Dicembre 2021, alle ore 12.00, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Speaker: *Lorenzo Masoero *(Amazon) Title: *Improved prediction and optimal sequencing strategies for genomic variant discovery via Bayesian nonparametrics* Abstract:Despite the advent of Big Data, data-gathering in many domains can still be an expensive process that necessitates careful planning when operating under a fixed, limited budget. For instance, sequencing new genomic data is a complex procedure that requires careful tuning: researchers can spend resources to sequence a greater number of genomes (quantity), or spend resources to sequence genomes with increased accuracy (quality). In this talk, I consider the common setting in which scientists have already conducted a pilot study to reveal variants in a genome and are contemplating a follow-up study. Spending additional resources has the potential to reveal new variations in the genome, and thereby new genetic insights. Therefore, practitioners are interested in (i) predicting how many new discoveries they will make under different experimental design choices. In turn, they can leverage these predictions to optimally allocate available resources in the design of a future experiment, e.g. (ii) to maximize the number of future discoveries or (iii) to optimize the usefulness of a future experiment for the task at hand, e.g. the power of an associated statistical test. I discuss novel methodologies to solve the problems mentioned above. Our approach relies on a Bayesian nonparametric formulation that facilitates (i) prediction for the number of new variants in the follow-up study based on the pilot study. We show empirically that, when experimental conditions are kept constant between the pilot and follow-up, our method's prediction is competitive with the best existing methods. Unlike current methods, though, our new method allows practitioners to change experimental conditions between the pilot and the follow-up. We demonstrate how this distinction allows our method to be used for more realistic predictions and for optimal allocation of a fixed budget between quality and quantity. In particular, we first show how, under a fixed budget, my predictions can be used to maximize (ii) the number of new genomic variants discovered in a follow-up study. Last, we show how our framework can guide practitioners in other experimental design problems, and specifically how to achieve (iii) the highest possible power in statistical tests in the context of rare variants association studies. ------------------------------------------------ In ottemperanza alle norme anti Covid, per partecipare in presenza è necessario prenotarsi tramite il seguente form online: https://forms.gle/jVPLoDCQ1ANSB5dg8 Sarà possibile seguire il seminario anche in streaming: Join Zoom Meeting <https://us02web.zoom.us/j/88971670320?pwd=VXFseHNlYm5EKzFmZ25oTGdlRWw4QT09> Meeting ID: 889 7167 0320 Passcode: 362208 Il seminario è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats Cordiali saluti, Pierpaolo De Blasi --- University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/>

(PMS)^2 online talk: Martin Huesmann (Dec 13, 5:30pm)
by Mario Maurelli 08 Dec '21

08 Dec '21

Dear colleagues, We are happy to announce the following online talk: Speaker: *Martin Huesmann* (Universität Münster) *Title*: A fluctuation result for the optimal matching problem *Abstract*: The optimal matching problem is one of the classical random optimization problems. While the asymptotic behavior of the expected cost is well understood only little is known for the asymptotic behavior of the optimal couplings - the solutions to the optimal matching problem. In this talk we show that at all mesoscopic scales the displacement under the optimal coupling converges in suitable Sobolev spaces to a Gaussian field which can be identified as the curl-free part of a vector Gaussian free field. Based on joint work with Michael Goldman. Date and time: *Monday December 13, 17:30-18:30* (Rome time zone) *Zoom link*: https://us02web.zoom.us/j/8342220461 This is a talk of the *(PMS)^2: Pavia-Milano Seminar series on Probability and Mathematical Statistics* organized jointly by the universities Milano-Bicocca, Pavia, Milano-Politecnico and Milano-Statale. For more information see the dedicated webpage: https://paviamilanoseminars.wordpress.com/ Participation is free and welcome! Best regards The organizers (Mario Maurelli, Carlo Orrieri, Maurizia Rossi, Margherita Zanella)

Reminder -- Online Quantitative Finance Seminars @SNS, December 10, 2021
by Giulia Livieri 07 Dec '21

07 Dec '21

Dear all, We would like to announce the following two Online Seminars @SNS: *December 10, 2021 at 3PM (CEST)* *Speaker: *Prof. Agostino Capponi (Columbia University) *Title: * The Adoption of Blockchain-based Decentralized Exchanges (joint work with Dr. Ruizhe Jia) *Abstract: *We show that the blockchain order execution mechanism and liquidity pooling create arbitrage rents in decentralized exchanges. The arbitrage rent raises the cost of liquidity provision and imposes negative externalities on users of the underlying blockchain. In equilibrium, automated market makers (AMMs) are adopted by liquidity providers only if exchange rates of token pairs are sufficiently stable. A pricing curve with higher curvature reduces arbitrage rents, but also decreases trading activities. We provide statistical support for our main model implications using transaction-level data of AMMs. *Link: * https://teams.microsoft.com/l/meetup-join/19%3ameeting_NjAyODk0YzQtNmVmYS00… We are looking forward to seeing you at the seminars!

And how can we do so at a given level of confidence? This question is central to a great deal of methods for functional data, which require low-dimensional representations whether by functional PCA or other methods. The difficulty is that the determination is to be made on the basis of i.i.d. replications of the process observed discretely and with measurement error contamination. This adds a ridge to the empirical covariance, obfuscating the underlying dimension. We describe a matrix-completion inspired test statistic that circumvents this issue by measuring the best possible least square fit of the empirical covariance's off-diagonal elements, optimised over covariances of given finite rank. For a fixed grid of sufficiently large size, we determine the statistic's asymptotic null distribution as the number of replications grows. We then use it to construct a bootstrap implementation of a stepwise testing procedure controlling the family-wise error rate corresponding to the collection of hypotheses formalising the question at hand. Under minimal regularity assumptions we prove that the procedure is consistent and that its bootstrap implementation is valid. The procedure circumvents smoothing and associated smoothing parameters, is indifferent to measurement error heteroskedasticity, and does not assume a low-noise regime. Based on joint work with Anirvan Chakraborty. -----------------------------------------------------------------------------

Webinars PRISMA
by c.ceci＠unich.it 30 Nov '21

30 Nov '21

Buon pomeriggio a tutti, abbiamo il piacere di annunciare il prossimo webinar promosso dal Gruppo UMI PRISMA: - Lunedi’ 6 dicembre 2021 ore 16-18 - ore 16, Giulia Di Nunno Titolo: On time changed Lévy noises in modelling, dynamics and control Abstract: The study of time change lays at the intersection of probability and statistics and have interesting potential in the modelling of different phenomena. These models are appealing, since they seem quite close to classical Lévy structures, often easy to simulate, though they are still statistically very different, as they may loose important properties, such as independent increments and Markovianity. It clearly all depends on the time change applied! When it comes to stochastic calculus, stochastic dynamics, and control, we shall see how the use of the interplay of partial information techniques and enlargement of filtrations can help dealing with such dynamics. - ore 17, Alessandra Cretarola Titolo: Optimal reinsurance and investment under common shock dependence between the financial and the actuarial market Abstract: We study the optimal proportional reinsurance and investment strategy for an insurance company which experiences both ordinary and catastrophic claims and wishes to maximize the expected exponential utility of its terminal wealth. We propose a model where the insurance framework is affected by environmental factors, and aggregate claims and stock prices are subject to common shocks, i.e. drastic events such as earthquakes, extreme weather conditions, or even pandemics, that have an immediate impact on the financial market and simultaneously induce insurance claims. Using the classical stochastic control approach based on the Hamilton-Jacobi- Bellman equation, we provide a verification result for the value function via classical solutions to two backward partial differential equations and characterize the optimal strategy. Finally, we discuss the effect of the common shock dependence via a comparison analysis.

Corso FREQUENTIST LIMITS FROM BAYESIAN STATISTICS
by Matteo Ruggiero 30 Nov '21

30 Nov '21

Cari colleghi, nell’ambito del programma di Visiting Professors della Laurea Magistrale in Stochastics and Data Science dell’Università di Torino (alla pagina https://www.master-sds.unito.it/go/visiting <https://www.master-sds.unito.it/go/visiting> il programma completo per il presente a.a.), con piacere annunciamo il seguente corso: -------------------------------------- Bas KLEIJN (University of Amsterdam) FREQUENTIST LIMITS FROM BAYESIAN STATISTICS We look at the role that the posterior can play in frequentist statistics, with special attention for large-sample limits. There exists an intimate relationship between hypothesis testing and concentration of posterior measure, which combines with a notion called remote contiguity to obtain frequentist convergence results from sequences of Bayesian posterior measures. We shall cover frequentist forms of posterior consistent estimation, rates of posterior convergence, as well as asymptotic uncertainty quantification by enlargement of credible sets and hypothesis testing/model selection with Bayes factors.

Seminar in Statistics GONZALO MENA
by Pierpaolo De Blasi 22 Nov '21

22 Nov '21

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 26 Novembre 2021, alle ore 12.00, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Speaker: *Gonzalo Mena *(University of Oxford) Title: *On the unreasonable effectiveness of Sinkhorn algorithm for learning permutations and entropic optimal transport* Abstract: Sinkhorn's algorithm realizes the solution of entropy-regularized linear programs on certain matrix polytopes. In the past years, the interest in this algorithm has grown considerably because of its usefulness as a tool for the modeling of permutations, and because of its fundamental role in the solution of an entropic optimal transport problem, also called the Schrödinger bridge. In this talk, I will give an overview of my work in relation to these two areas. First, regarding entropic optimal transport, I will argue that this tool is valuable for deriving sensible statistical procedures. Indeed, we show that it enjoys a substantially better sample complexity compared to optimal transport, which suffers from the curse of dimensionality. Also, in the more applied setup of model-based clustering we show that it can be used as an alternative to the log-likelihood, since it has fewer bad local optima. Based on this observation, we develop a new algorithm, Sinkhorn-EM, in which we only modify the E-step to solve an Entropic Optimal Transport problem. Our algorithm is shown to attain better practical performance. Second, regarding permutations, I will describe some successful applications in Deep Learning, and in neuroscience, for the inference of neural identities in C.elegans worms.

The performance of PET-ABC was compared with weighted non-linear least squares (WNLS) in terms of reliability of kinetic parameter estimation and statistical power for model selection. Dynamic PET data based on 1-tissue and 2-tissue compartmental models were simulated with 2 noise models and 3 noise levels. PET-ABC was used to evaluate the reliability of parameter estimates under each condition. It was also used to perform model selection for a simulated noisy dataset composed of a mixture of 1- and 2-tissue compartment kinetics. Finally, PET-ABC was used to analyze a non-steady state dynamic study performed on a fully conscious rat administered either 2 mg.kg-1 amphetamine or saline 20 min after tracer injection.

2022 PIMS-CRM Summer School in Probability
by Faggionato, Alessandra 22 Nov '21

22 Nov '21

Buongiorno, ricevo da Omer Angel ed inoltro volentieri. Saluti Alessandra Faggionato %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Dear colleague, The 2022 PIMS-CRM Summer School in Probability will be held at the University of British Columbia from May 30 to June 24, 2022. This month-long program, originally planned for 2020, is especially appropriate for young researchers in probability, although others may of course attend. While there is still uncertainty stemming from covid regarding travel and conferences, we are hopeful that the school will be able to run this summer. The main courses will be given by Ivan Corwin (Columbia University), and Frank den Hollander (University of Leiden). Their respective titles are Interacting particle systems, growth models, stochastic PDEs and directed polymers through the lens of the stochastic six vertex model and Metastability for interacting particle systems Three 3-hour mini courses will be given by Paul Bourgade, Jean-Francois Le Gall and Nike Sun. There will also be an opportunity for some participants to give short talks on their own research. More information about the program may be found on the School's website at http://www.math.ubc.ca/Links/ssprob22 Graduate students and postdoctoral fellows who will attend the entire summer school can apply for financial support for on-campus accommodation through mathjobs: https://www.mathjobs.org/jobs/list/18950 Major support for the conference has been provided by PIMS, CRM, NSF, and the Department of Mathematics at UBC. Questions can be directed to one of the UBC organizers listed below. Please forward this email to students and postdocs who may be interested in attending. Sincerely, Louigi Addario-Berry <louigi.addario(a)mcgill.ca> Omer Angel <angel(a)math.ubc.ca> Jonathan Hermon <jhermon(a)math.ubc.ca> Mathav Murugan <mathav(a)math.ubc.ca> Gordon Slade <slade(a)math.ubc.ca>
