Abstract

The gradient method is the simpliest method for unconstrained optimization, as in each iteration, the next iteration point is obtained from the current one by moving along the gradient direction. Variations of the gradient methods, such as stochastic gradient algorithms are widely used for machine learning and other AI problems. In this talk, we give some new stepsizes
for the gradient method based on subspace approximations, which presents a new approach for constructing gradient algorithms.
