Researchers have introduced Curvature-Weighted Gradient Diversity (CWGD), a novel metric designed to better measure optimization noise in machine learning models. Unlike traditional methods that treat all parameter directions equally, CWGD accounts for the impact of curvature, recognizing that high-curvature directions are less sensitive to noise. This new measure, when used in a CWGD-Cosine learning-rate schedule, has demonstrated the potential to reduce final optimization error by approximately 20% compared to standard cosine annealing in quadratic settings, with negligible overhead.
