Probably approximate Bayesian computation: nonasymptotic convergence of ABC under misspecification

no code implementations19 Jul 2017 James Ridgway

In this paper we develop theoretical bounds for the distance between the statistics used in ABC.

Concentration of tempered posteriors and of their variational approximations

no code implementations28 Jun 2017 Pierre Alquier, James Ridgway

While Bayesian methods are extremely popular in statistics and machine learning, their application to massive datasets is often challenging, when possible at all.
