L-svrg and l-katyusha with arbitrary sampling

WebStochastic gradient-based optimization methods, such as L-SVRG and its accelerated variant L-Katyusha (Kovalev et al., 2024), are widely used to train machine learning models.The theoretical and empirical performance of L-SVRG and L-Katyusha can be improved by sampling observations from a non-uniform distribution (Qian et al., 2024). WebJan 24, 2024 · The L-SVRG method, formalized as Algorithm 1, is inspired by the original SVRG (Johnson & Zhang, 2013) method. We remove the outer loop present in SVRG and instead use a probabilistic update of the full gradient. 1 1 1 This idea was indepdentnly explored by Hofmann et al. ( 2015 ) ; we have learned about this work after a first draft of …
