Webto implicit sgd, the stochastic proximal gradient algorithm rst makes a classic sgd update (forward step) and then an implicit update (backward step). Only the forward step is stochastic whereas the backward proximal step is not. This may increase convergence speed but may also introduce in-stability due to the forward step. Interest on ... WebWhile the upper bounds of algorithmic stability of SGD have been extensively studied, the tightness of those bounds remains open. In addition to uniform stability, an average stability of the SGD is studied in Kuzborskij & Lampert (2024) where the authors provide data-dependent upper bounds on stability1.

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.
