Global Convergence in Neural ODEs: Impact of Activation Functions

ICLR 2025oral

Neural Ordinary Differential Equations (ODEs) have been successful in various applications due to their continuous nature and parameter-sharing efficiency. However, these unique characteristics also introduce challenges in training, particularly with respect to gradient computation accuracy and conv…

Wide Neural Networks as Gaussian Processes: Lessons from Deep Equilibrium Models

NeurIPS 2023poster

Neural networks with wide layers have attracted significant attention due to their equivalence to Gaussian processes, enabling perfect fitting of training data while maintaining generalization performance, known as benign overfitting. However, existing results mainly focus on shallow or finite-depth…

A global convergence theory for deep ReLU implicit networks via over-parameterization

ICLR 2022poster

Implicit deep learning has received increasing attention recently due to the fact that it generalizes the recursive prediction rule of many commonly used neural network architectures. Its prediction rule is provided implicitly based on the solution of an equilibrium equation. Although a line of rece…

On the Convergence of Randomized Bregman Coordinate Descent for Non-Lipschitz Composite Problems

ICASSP 2021accepted

We propose a new randomized Bregman (block) coordinate descent (RBCD) method for minimizing a composite problem, where the objective function could be either convex or nonconvex, and the smooth part are freed from the global Lipschitz-continuous (partial) gradient assumption. Under the notion of rel…
