Practical Precoding via Asynchronous Stochastic Successive Convex Approximation
Basil M. Idrees, Javed Akhtar, Ketan Rajawat
We consider stochastic optimization of a smooth non-convex loss function with a convex non-smooth regularizer. In the online setting, where a single sample of the stochastic gradie…
