Implicit Greedy Rank Learning in Autoencoders via Overparameterized Linear Networks
Shih-Yu Sun, Vimal Thilak, Etai Littwin +2
Deep linear networks trained with gradient descent yield low rank solutions, as is typically studied in matrix factorization. In this paper, we take a step further and analyze impl…

Implicit Acceleration and Feature Learning in Infinitely Wide Neural Networks with Bottlenecks
Etai Littwin, Omid Saremi, Shuangfei Zhai +4
We analyze the learning dynamics of infinitely wide neural networks with a finite sized bottle-neck. Unlike the neural tangent kernel limit, a bottleneck in an otherwise infinite w…
