A Mean Field View of the Landscape of Two-Layers Neural Networks

18 Apr 2018 Song Mei Andrea Montanari Phan-Minh Nguyen

Multi-layer neural networks are among the most powerful models in machine learning, yet the fundamental reasons for this success defy mathematical understanding. Learning a neural network requires to optimize a non-convex high-dimensional objective (risk function), a problem which is usually attacked using stochastic gradient descent (SGD)... (read more)
