New logarithmic step size for stochastic gradient descent
《Frontiers of Computer Science》2025年第1期109-118,共10页Mahsa Soheil SHAMAEE Sajad Fathi HAFSHEJANI Zeinab SAEIDIAN 
first author is partially supported by the University of Kashan(1143902/2).
In this paper, we propose a novel warm restart technique using a new logarithmic step size for the stochastic gradient descent (SGD) approach. For smooth and non-convex functions, we establish an O(1/√T) convergence ...
