Webstability of SGD can be controlled by forms of regulariza-tion. In (Kuzborskij & Lampert, 2024), the authors give stability bounds for SGD that are data-dependent. These bounds are smaller than those in (Hardt et al., 2016), but require assumptions on the underlying data. Liu et al. give a related notion of uniform hypothesis stability and show ... try me im new

WebJun 21, 2024 · Better “stability” of SGD[12] [12] argues that SGD is conceptually stable for convex and continuous optimization. First, it argues that minimizing training time has the benefit of decreasing ... WebThe batch size parameter is just one of the hyper-parameters you'll be tuning when you train a neural network with mini-batch Stochastic Gradient Descent (SGD) and is data dependent. The most basic method of hyper-parameter search is to do a grid search over the learning rate and batch size to find a pair which makes the network converge.
