On Implicit Regularization in Deep Learning
summary
Shows that for matrix completion parameterized as a product of d×d layers, gradient descent from near-zero consistently recovers the low-rank ground truth by driving singular values with a rich-get-richer among singular values dynamic so rank grows gradually and low-rank minima are reached. Also proves for a two-layer nonlinear net that early training closely matches a linear model trained by gradient descent, with experiments confirming the coupling and the initial linearization.
