Constrained and Preconditioned Stochastic Gradient Method
Hong Jiang, Gang Huang, Paul Wilford +1
We consider stochastic approximations which arise from such applications as data communications and image processing. We demonstrate why constraints are needed in a stochastic appr…

A Stochastic Conjugate Gradient Method for Approximation of Functions
Hong Jiang, Paul Wilford
A stochastic conjugate gradient method for approximation of a function is proposed. The proposed method avoids computing and storing the covariance matrix in the normal equations f…
