Working Group Information


WOGAS 3 will focus on several working group areas, which are listed below. Information relating to each of those groups will also be posted here as it becomes available.

o Decision Geometry - Organisers: Phil Dawid and Matt Parry

Paper for Discussion [PDF]

o Geometry of MCMC - Organisers: Mark Girolami and Matt Parry

Three 20 min talks on
