Communication-Efficient Asynchronous Stochastic Frank-Wolfe over Nuclear-norm Balls
2019 · arXiv (Cornell University)
Large-scale machine learning training suffers from two prior challenges, specifically for nuclear-norm constrained problems with distributed systems: the synchronization slowdown due to the straggling workers, and high communication costs. In this work, we propose an …

Beyond Uniform Smoothness: A Stopped Analysis of Adaptive SGD
2023 · arXiv (Cornell University)
This work considers the problem of finding a first-order stationary point of a non-convex function with potentially unbounded smoothness constant using a stochastic gradient oracle. We focus on the class of $(L_0,L_1)$-smooth functions proposed by …

Semantic Image Inversion and Editing using Rectified Stochastic Differential Equations
2024 · arXiv (Cornell University)
Generative models transform random noise into images; their inversion aims to transform images back to structured noise for recovery and editing. This paper addresses two key tasks: (i) inversion and (ii) editing of a real …
