A Progressive Batching L-BFGS Method for Machine Learning

ICML 2018oral

The standard L-BFGS method relies on gradient approximations that are not dominated by noise, so that search directions are descent directions, the line search is reliable, and quasi-Newton updating yields useful quadratic models of the objective function. All of this appears to call for a full batc…

Faster CNNs with Direct Sparse Convolutions and Guided Pruning

ICLR 2017poster

Phenomenally successful in practical inference problems, convolutional neural networks (CNN) are widely deployed in mobile devices, data centers, and even supercomputers. The number of parameters needed in CNNs, however, are often large and undesirable. Consequently, various methods have been develo…

On Large-Batch Training for Deep Learning: Generalization Gap and Sharp Minima

ICLR 2017oral

The stochastic gradient descent (SGD) method and its variants are algorithms of choice for many Deep Learning tasks. These methods operate in a small-batch regime wherein a fraction of the training data, say $32$--$512$ data points, is sampled to compute an approximation to the gradient. It has bee…
