Nonsmooth nonconvex stochastic heavy ball

open access: yes, 2023
Motivated by the conspicuous use of momentum-based algorithms in deep learning, we study a nonsmooth nonconvex stochastic heavy ball method and show its convergence. Our approach builds upon semialgebraic (definable) assumptions commonly met in practical

A Scaling Transition Method from SGDM to SGD with 2ExpLR Strategy

open access: yesApplied Sciences, 2022
In deep learning, the vanilla stochastic gradient descent (SGD) and SGD with heavy-ball momentum (SGDM) methods have a wide range of applications due to their simplicity and great generalization. This paper uses an exponential scaling method to realize a
