WebUnderstanding the properties of neural networks trained via stochastic gradient descent (SGD) is at the heart of the theory of deep learning. In this work, we take a mean-field view, and consider a two-layer ReLU network trained via noisy-SGD for a ... Webthe convexity that is heavily leveraged in (Chizat & Bach, 2024) is lost. We bypass this issue by requiring a sufficient expressivity of the used nonlinear representation, allowing to characterize global minimizer as optimal approximators. The convergence and optimality of policy gradient algorithms (including in the entropy-regularized ...
