IB has succeeded in explaining the objective … Webconditional PAC-Bayesian bounds, where ‘conditional’ means that one can use priors conditioned on a joint training and ghost sample. This allows us to get nontrivial PAC-Bayes and MI-style bounds for general VC classes, something recently shown to be impossible with standard PAC-Bayesian/MI bounds.
