Testing Stationarity Concepts for ReLU Networks: Hardness, Regularity, and Robust Algorithms

no code implementations23 Feb 2023 Lai Tian, Anthony Man-Cho So

This implies that testing a certain stationarity concept for a modern nonsmooth neural network is in general computationally intractable.

Practical Schemes for Finding Near-Stationary Points of Convex Finite-Sums

no code implementations NeurIPS 2021 Kaiwen Zhou, Lai Tian, Anthony Man-Cho So, James Cheng

In convex optimization, the problem of finding near-stationary points has not been adequately studied yet, unlike other optimality measures such as the function value.
