ISBA Webinars on Bayesian Analysis Articles (2019–present).This webpage gathers an exceptional collection of webinars discussing Bayesian Analysis articles since 2019. For anyone curious about the frontiers of Bayesian statistics, this series brings together cutting-edge research from world-class experts. The talks span topics such as model uncertainty and missing data, new perspectives on stick-breaking models, sparse Bayesian factor analysis, and advances in causal inference under model mis-specification. Other contributions cover nonparametric priors, spatio-temporal modeling of Arctic sea ice, Bayesian regression trees for causal inference, and much more.The next BA webinar will focus on the paper “Model Uncertainty and Missing Data: An Objective Bayesian Perspective” by G. García-Donato, M. Eugenia Castellanos, S. Cabras, A. Quirós, and A. Forte. There will be four invited discussants: M. Clyde, M. Ferreira, A. Ly, and J. Rubio. It is scheduled for November 5, 2025 (4:00 PM UTC | 11:00 AM EST | 5:00 PM CET). Registration will be announced later on this webpage.ISBA YouTube Channel.All recorded webinar videos are available on the ISBA YouTube channel. Beyond the webinars, the channel hosts curated playlists from ISBA World Meetings (2012, 2016, 2018, 2021, 2022, 2024), specialized workshops and seminars (ABI, BNP, BayesComp), as well as content from ISBA Sections (j-ISBA, BNP, BioPharma, Industrial).These resources deserve broad visibility. I warmly encourage you to explore them, share them within your networks, and let us know your feedback.— Julyan, on behalf of the ISBA Social Media team
IISA 2024

The IISA 2024 conference was held at the Cochin University of Science and Technology (CUSAT), where talks and posters took place. Among the sessions I attended, I attended a talk on colliding random walks that made three or more impossible in the limit, missed the only privacy talk that I could have attended by Vinayak Rao for indulging into a dawnish swimming session in the very decent hotel pool. In the first session I organised, loosely connected with BNP, Antonietta Mira presented a recent work on predicting EU carbon compensation rates, using a information imbalance rank substitute to correlation that could prove quite interesting in privacy settings, albeit no invariant to reparameterisations (with potential connections with Wasserstein distances), Sonia Petrone gave an overview on her substantial amount of work on empirical Bayes in Bayes (EBIB), making me wonder at natural ABC or EM ways to bypass the computation of the empirical Bayes hyperparameter computation (but also on measuring the overfitting degree of EBIB-ing), maybe exploiting the representation of the marginal as an average of predictive, and Debdeep Pati argued towards an interpretable and robust ML, using for estimation divergence a mixture of two KL’s that is remindful of GANs (as well as of Lasso and exponentially tilted empirical likelihood à la Chib & al.), implemented by a form of Bbootstrap. Plus enjoying a locally flavoured acronym, namely BETEL.
The second session I organised was centred on Bayesian computations, with both Sid Chib and Ritabrata Dutta (U Warwick) presenting a Bayesian modelling of difference-in-difference models in clinical trials and several works on (score based) generalized Bayes models with Shreya Roy (U Warwick), who further won a poster prize at IISA 2024. I terminated the session with a talk on our insufficient Gibbs sampler, which connected with some aspects of both Sid’s and Rito’s talks.
As in earlier editions of IISA I attended, the local organisation was most enjoyable, from supportive staff and students, relaxed atmosphere, easy commutes, heaps of great food, and unlimited chai! Plus meeting and listening to participants I had met in these earlier editions. Looking forward the 2026 edition!
