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 WebUniform stability is a notion of algorithmic stability that bounds the worst case change in the model output by the algorithm when a single data point in the dataset is replaced. An influential work of Hardt et al. (2016) provides strong upper bounds on the uniform stability of the stochastic gradient descent (SGD) algorithm on sufficiently ... city close to las vegas

Webby SDE. For the ﬁrst question, we extend the linear stability theory of SGD from the second-order moments of the iterator of the linearized dynamics to the high-order moments. At the interpolation solutions found by SGD, by the linear stability theory, we derive a set of accurate upper bounds of the gradients’ moment. Webconditions. 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.
