Nicolas Le Roux is a Canada CIFAR AI Chair at Mila and an adjunct professor at McGill University’s School of Computer Science. He is leading the optimization effort as a research scientist at Google Brain Montreal.
Le Roux is interested in understanding how the interplay between noise and curvature affects convergence speed and generalization in stochastic optimization and understanding the dynamics of optimization in reinforcement learning, especially policy-gradient methods.
