Black Box Lie Group Preconditioners for SGD

2 code implementations8 Nov 2022 XiLin Li

A matrix free and a low rank approximation preconditioner are proposed to accelerate the convergence of stochastic gradient descent (SGD) by exploiting curvature information sampled from Hessian-vector products or finite differences of parameters and gradients similar to the BFGS algorithm.
