"Webrely on SGD exhibiting a coarse type of stability: namely, the weights obtained from training on a subset of the data are highly predictive of the weights obtained from the whole data set. We use this property to devise data-dependent priors and then verify empirically that the resulting PAC-Bayes bounds are much tighter. 2 Preliminaries " - Data dependent algorithm stability of sgd
