We use this property to devise data-dependent priors and then verify empirically that the resulting PAC-Bayes bounds are much tighter. 2 Preliminaries ira state income tax withholding

Webstability of SGD can be controlled by forms of regulariza-tion. In (Kuzborskij & Lampert, 2024), the authors give stability bounds for SGD that are data-dependent. These bounds are smaller than those in (Hardt et al., 2016), but require assumptions on the underlying data. Liu et al. give a related notion of uniform hypothesis stability and show ...
