The paper presents a new approach to understanding how machine learning models generalize and optimize by analyzing the complexity of their gradients. It introduces a metric called Loss Gradient Gaussian Width (LGGW) to measure this complexity and shows that it can be used to provide guarantees on generalization performance and optimization efficiency. The results are particularly relevant for deep networks, where the authors show that the LGGW is related to the Gaussian width of the featurizer, providing a new way to bound the performance of these models. This work has the potential to lead to more accurate and efficient machine learning algorithms.
Low GrooveSquid.com (original content) Low Difficulty Summary
The paper finds a new way to make sure that machine learning models do well on new data by looking at how their gradients change. It introduces a new measure called LGGW, which shows how complex the gradients are. The authors then use this measure to prove that some models will perform well on new data and others won’t. They also show that some techniques used in training deep networks don’t actually hurt performance as much as people thought. This could help make machine learning models better.
