Then, we consider the case of objectives with bounded second derivative and show that in this case a small tweak to the momentum formula allows normalized SGD with momentum to find an ∈-critical point in O(1/∈~(3,5)) iterations, matching the best-known rates without accruing any ...
momentumPerMB: this alternative way of specifying momentum mimics the behavior of common toolkits. E.g. specifying 0.9 means that the previous gradient will be retained with a weight of 0.9. Note, however, that, unlike some other toolkits, CNTK still uses a unit-gain filter, i.e. the new...

these same simple optimizers (SGD without momentum in particular) have a greater tendency to get stuck in local minima. As usual, it appears thatthe best solution may lie in ensembles of optimizers as opposed to relying on just one method - combining the pros of each to obtain the best of...
