UNIVAQ RANDOM TALKS - The Ph.D. COLLOQUIUM ________________________________ Online conferences on Probability and Applications at DISIM - UNIVERSITÁ DI L'AQUILA Monday June 8th 2:30 p.m. - ZOOM Videoconference platform Prof. Philip Protter Statistics Department Columbia University Nonlinear Valuation in Credit Risk Everybody is welcome, please subscribe by the following form The day of the seminar, participants will receive an invitation by e-mail https://docs.google.com/forms/d/e/1FAIpQLSfivXQHs0ZbxtQG8anBnzTSy1Tq_uWN7sG… (max. 100 participants) No need to subscribe, if, in a previous form, you asked to be always included Abstract: In a series of recent papers, Damiano Brigo, Andrea Pallavicini, and co-authors have shown that the value of a contract in a Credit Valuation Adjustment (CVA) setting, being the sum of the cash flows, can be represented as a solution of a decoupled forward-backward stochastic differential equation (FBSDE). CVA is the difference between the risk-free portfolio value and the true portfolio value that takes into account the possibility of a counter party's default. In other words, CVA is the market value of counter party credit risk. This has achieved noteworthy importance after the 2008 financial debacle, where counter party risk played an under-modeled but huge risk. In their analysis, Brigo et al make the classical assumption of conditional independence of the default times, given the risk-free market filtration. This does not allow for the possibility of simultaneous defaults. We weaken their assumption, replacing it with a martingale orthogonality condition. This in turn changes the form of the BSDE that arises from the model. My talk is based on joint work with Aditi Dandapani. --------------------------------- Fabio Antonelli DISIM - Università di L'Aquila

Probability Webminar: Giuseppe Cannizzaro (University of Warwick) [Padova 05/06, 11.00]
by alessandra bianchi 27 May '20

27 May '20

Dear Colleagues, We would like to invite you to the following Probability seminar that will take place on June 05 at 11 by the zoom platform. ________________________________________________________ Speaker: Giuseppe Cannizzaro (University of Warwick) Title: A new Universality Class in (1+1)-dimensions: the Brownian Castle 05 JUNE (Friday) - 11:00 - zoom link: TBA The link and password to access the seminar will be available at the following webpage https://www.math.unipd.it/~bianchi/seminari/ Abstract: In the context of randomly fluctuating interfaces in (1+1)-dimensions two Universality Classes have generally been considered, the Kardar-Parisi-Zhang and the Edwards-Wilkinson. Models within these classes exhibit universal fluctuations under 1:2:3 and 1:2:4 scaling respectively. Starting from a modification of the classical Ballistic Deposition model we will show that this picture is not exhaustive and another Universality Class, whose scaling exponents are 1:1:2, has to be taken into account. We will describe how it arises, briefly discuss its connections to KPZ and introduce a new stochastic process, the Brownian Castle, deeply connected to the Brownian Web, which should capture the large-scale behaviour of models within this Class. This talk is based on a joint ongoing work with Martin Hairer. -- Alessandra Bianchi Dip. di Matematica Università di Padova Via Trieste, 63 - 35121 Padova, Italy phone: +39 049 827 14 06 fax: +39 049 827 14 28 e-mail: bianchi(a)math.unipd.it http://www.math.unipd.it/~bianchi/

PhD course "Fractional Brownian motion and non-Markovian modeling" by P. Pigato
by Lucia Caramellino 26 May '20

26 May '20

Dipartimento di Matematica, Università di Roma “Tor Vergata” PhD School in Mathematics Announcement of a PhD course (10 hours, online) Paolo Pigato (Università di Roma "Tor Vergata", WIAS Berlin): Fractional Brownian motion and non-Markovian modeling Abstract. In several applications of stochastic analysis (financial engineering, telecommunication networks, ...), it is desirable to model real-world quantities which are non-Markovian, for example because the noise process exhibits slowly decaying auto-correlations and long memory. In this course we will focus on fractional Brownian motion, a prototypical example of non-Markovian process. Such process is a generalisation of Brownian motion with Holder regularity possibly different than 1/2 and it is not a martingale. We will consider large deviations problems, simulation methods and some examples of application. Schedule. - Friday June 05, 2020; h. 14-16 - Tuesday June 09, 2020; h. 14-16 - Thursday June 11, 2020; h. 14-16 - Tuesday June 16, 2020; h. 14-16 - Thursday June 19, 2020; h. 14-16 Information at http://www.mat.uniroma2.it/~dott/corsi.html <http://www.mat.uniroma2.it/~dott/corsi.html> http://www.mat.uniroma2.it/~macci/corso-dottorato-pigato.htm <http://www.mat.uniroma2.it/~macci/corso-dottorato-pigato.htm> How to join the course.

Webinar RIGON
by Pierpaolo De Blasi 22 May '20

22 May '20

WEBINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/research/webinars/> Venerdì 29 Maggio 2020, alle ore 15:00, si terrà il seguente webinar: ------------------------------------------------ Tommaso RIGON (Duke University) *A generalized Bayes framework for probabilistic clustering* Abstract: Clustering methods such as k-means and its variants are standard tools for finding groups in the data. However, despite their huge popularity, the underlying uncertainty can not be easily quantified. On the other hand, mixture models represent a well-established inferential tool for probabilistic clustering, but they are characterized by severe computational bottlenecks and may have unreliable solutions in presence of misspecifications. Instead, we rely on a generalized Bayes framework for probabilistic clustering based on Gibbs posteriors. Broadly speaking, in such a setting the log-likelihood is replaced by an arbitrary loss function and this arguably leads to much richer families of clustering methods. Our contribution is two-fold: first, we describe a clustering pipeline for efficiently finding groups and then quantifying the associated uncertainty. Second, we discuss two broad classes of loss functions which have advantages in terms of analytic tractability and interpretability. Specifically, we consider losses based on Bregman divergences and pairwise dissimilarities and we show they can be interpreted as profile and composite log-likelihoods, respectively. Full Bayesian inference is conducted via Gibbs sampling but efficient deterministic algorithms are available for point estimation. As an important byproduct of our work, we show that several existing clustering approaches can be interpreted as generalized Bayesian estimators under specific loss functions. Hence, our methodology can be also used to formally quantify the uncertainty in widely used clustering approaches. (joint work with Amy Herring and David Dunson, Duke University) ------------------------------------------------ Chiunque volesse collegarsi al webinar è pregato di inviare una email entro mercoledi 27 Maggio a pierpaolo.deblasi(a)unito.it Il webinar è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats in collaborazione con il Collegio Carlo Alberto.
