Online Learning Using Only Peer Prediction

no code implementations10 Oct 2019 Yang Liu, David P. Helmbold

This paper considers a variant of the classical online learning problem with expert predictions.

Gradient descent with identity initialization efficiently learns positive definite linear transformations by deep residual networks

no code implementations ICML 2018 Peter L. Bartlett, David P. Helmbold, Philip M. Long

We provide polynomial bounds on the number of iterations for gradient descent to approximate the least squares matrix $\Phi$, in the case where the initial hypothesis $\Theta_1 = ... = \Theta_L = I$ has excess loss bounded by a small enough constant.

Online Learning of Combinatorial Objects via Extended Formulation

no code implementations17 Sep 2016 Holakou Rahmanian, David P. Helmbold, S. V. N. Vishwanathan

We present applications of our framework to online learning of Huffman trees and permutations.

Surprising properties of dropout in deep networks

no code implementations14 Feb 2016 David P. Helmbold, Philip M. Long

We analyze dropout in deep networks with rectified linear units and the quadratic loss.

On the Inductive Bias of Dropout

no code implementations15 Dec 2014 David P. Helmbold, Philip M. Long

Dropout is a simple but effective technique for learning in neural networks and other settings.
