ABC World seminar

Posted in Books, pictures, Statistics, Travel, University life with tags , , , , , , , , , , , , on April 4, 2020 by xi'an

With most of the World being more or less confined at home, conferences cancelled one after the other, including ABC in Grenoble!, we are launching a fortnightly webinar on approximation Bayesian computation, methods, and inference. The idea is to gather members and disseminate results and innovation during these coming weeks and months under lock-down. And hopefully after!

At this point, the interface will be Blackboard Collaborate, run from Edinburgh by Michael Gutmann, for which neither registration nor software is required. Before each talk, a guest link will be mailed to the mailing list. Please register here to join the list.

The seminar is planned on Thursdays at either 9am or more likely 11:30 am UK (+1GMT) time, as we are still debating the best schedule to reach as many populated time zones as possible!, and the first speakers are

09.04.2020 Dennis Prangle Distilling importance sampling
23.04.2020 Ivis Kerama and Richard Everitt Rare event SMC²
07.05.2020 Umberto Picchini Stratified sampling and bootstrapping for ABC
