Data dependent algorithm stability of sgd
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 ... 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. Rather than abandoning this approach, we take two steps: First, we run SGLD far beyond the point

WebWe propose AEGD, a new algorithm for optimization of non-convex objective functions, based on a dynamically updated 'energy' variable. The method is shown to be unconditionally energy stable, irrespective of the base step size. We prove energy-dependent convergence rates of AEGD for both non-convex and convex objectives, … http://proceedings.mlr.press/v80/dziugaite18a/dziugaite18a.pdf
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. WebFeb 1, 2024 · Abstract. The stability and generalization of stochastic gradient-based methods provide valuable insights into understanding the algorithmic performance of machine learning models. As the main ...
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. In this work, we report for the first 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 ...
