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 WebOct 23, 2024 · Abstract. We establish novel generalization bounds for learning algorithms that converge to global minima. We do so by deriving black-box stability results that only depend on the convergence of a ... asatidzah adalah

We will refer to the Entropy-SGD algorithm as Entropy-SGLD when the SGD step on local entropy is replaced by SGLD. The one hurdle to using data-dependent priors learned by SGLD is that we cannot easily measure how close we are to converging. Rather than abandoning this approach, we take two steps: First, we run SGLD far beyond the point Webconnection between stability and generalization of SGD in Section3and introduce a data-dependent notion of stability in Section4.
