a good start in Series B!

Just received the great news for the turn of the year that our paper on ABC using Wasserstein distance was accepted in Series B! Inference in generative models using the Wasserstein distance, written by Espen Bernton, Pierre Jacob, Mathieu Gerber, and myself, bypasses the (nasty) selection of summary statistics in ABC by considering the Wasserstein distance between observed and simulated samples. It focuses in particular on non-iid cases like time series in what I find fairly innovative ways. I am thus very glad the paper is going to appear in JRSS B, as it has methodological consequences that should appeal to the community at large.

questioning the Bayesian choice

When I woke up (very early!) in Oaxaca, on Remembrance Day, I noticed a long question about The Bayesian Choice contents on X validated. The originator of the question (OQ) was puzzled about several statements in the book on maximum entropy  methods, from the nature of the moment constraints, outside standard moments, to the existence of a maximum entropy prior (as exemplified by quantiles), to the deeper issue of the ultimate arbitrariness of “the” maximum entropy prior since it is also determined by the choice of the dominating measure. (Never neglect the dominating measure!) A more challenging concept, hopefully making it home with the OQ.
