I've spent the last week working in the beautiful (and intensely hot) Clermont-Ferrand in the south of France, in the fourth edition of the COIN residence program. These residence programs are aimed to bring together a diverse collection of astrophysicists (and others!) to live together in a house for a week, and collaborate intensely on a couple of statistical and/or machine learning problem in astrophysics. The house itself is super luxurious (by British standards, at least)
I had no idea how much work could be done in a single week, we have two papers in a pretty good state (from an almost cold start), and we expect to submit them in the next couple of weeks. I'm not sure how much I can say about them before then, but I'll write a summary here once they appear on the arXiv.
I would thoroughly recommend future incarnations of this meeting to anyone. The website is here; https://iaacoin.wixsite.com/crp2017
