Webinar RIGON

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.

WEBINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/research/webinars/> Venerdì 22 Maggio 2020, alle ore 12:00, si terrà il seguente webinar: ------------------------------------------------ Pierre JACOB (Harvard University) *Unbiased Markov chain Monte Carlo with couplings* Abstract: Various tasks in statistics involve numerical integration, for which Markov chain Monte Carlo (MCMC) methods are state-of-the-art. MCMC methods yield estimators that converge to integrals of interest in the limit of the number of iterations. This iterative asymptotic justification is not ideal; first, it stands at odds with current trends in computing hardware, with increasingly parallel architectures; secondly, the choice of "burn-in" or "warm-up" is arduous. This talk will describe recently proposed estimators that are unbiased for the expectations of interest while having a finite computing cost and a finite variance. They can thus be generated independently in parallel and averaged over. The method also provides practical upper bounds on the distance (e.g. total variation) between the marginal distribution of the chain at a finite step and its invariant distribution. The key idea is to generate "faithful" couplings of Markov chains, whereby pairs of chains coalesce after a random number of iterations. This talk will provide an overview of this line of research.
