Markov Chain Gradient Descent in Hilbert Spaces

Priyanka Roy, Susanne Saminger-Platz

In this paper, we study a Markov chain-based stochastic gradient algorithm in general Hilbert spaces, aiming at approximating the optimal solution of a quadratic loss function. We…

Online Regularized Learning Algorithms in RKHS with $I^^{2}$ - and $I ¨ $ -Mixing Sequences

Priyanka Roy, Susanne Saminger-Platz

In this paper, we study an online regularized learning algorithm in a reproducing kernel Hilbert spaces (RKHS) based on a class of dependent processes. We choose such a process whe…
