Convergence and Alignment of Gradient Descent with Random Backpropagation Weights

no code implementations NeurIPS 2021 Ganlin Song, Ruitu Xu, John Lafferty

In this paper we study the mathematical properties of the feedback alignment procedure by analyzing convergence and alignment for two-layer networks under squared error loss.

Meta Learning in the Continuous Time Limit

no code implementations19 Jun 2020 Ruitu Xu, Lin Chen, Amin Karbasi

In this paper, we establish the ordinary differential equation (ODE) that underlies the training dynamics of Model-Agnostic Meta-Learning (MAML).
