Webassuming prior stability. We show how this method leads to refinements of the PAC-Bayes bound mentioned above for infinite-Rényi divergence prior stability. Related Work. Our work builds on a strong line of work using algorithmic stability to derive generalization bounds, in particular [Bousquet and Elisseeff,2002,Feldman and Vondrak,2024, WebPAC-Bayesian inequalities allow to derive distribution- or data-dependent generalization bounds in the context of the stochastic prediction model discussed above. The usual PAC-Bayes analysis introduces a reference ‘data-free’ probability measure Q0 2M 1(H) on the hypothesis space H. The learned data-dependent distribution Q
