TMLW02 - SGD: stability, momentum acceleration and heavy tails

This talk will first review the so-called `ODE’ (for `Ordinary Differential Equations’) approach for the analysis of stochastic approximation algorithms of which stochastic gradient descent is a special case. Using that as a backdrop, certain analogous results will be presented for a class of algorithms with heavy tailed noise. This is joint work with V. Anantharam of Uni. of California at Berkeley.
