Combining Natural Gradient with Hessian Free Methods for Sequence Training

3 Oct 2018Adnan HaiderP. C. Woodland

This paper presents a new optimisation approach to train Deep Neural Networks (DNNs) with discriminative sequence criteria. At each iteration, the method combines information from the Natural Gradient (NG) direction with local curvature information of the error surface that enables better paths on the parameter manifold to be traversed...
