Fast Convergence of Stochastic Gradient Descent under a Strong Growth Condition
We consider optimizing a function smooth convex function $f$ that is the average of a set of differentiable functions $f_i$, under the assumption considered by Solodov... -
Almost sure convergence of stochastic gradient processes with matrix step sizes
We consider a stochastic gradient process, which is a special case of stochastic approximation process, where the positive real step size a_{n} is replaced by a random...
