Researchers have introduced GRAIN, a novel training algorithm designed to address learning instability in large, overparameterized deep learning models. GRAIN replaces the standard mean aggregation of gradients with a min-norm convex combination of group-wise gradients. This approach guarantees a non-negative inner product between the aggregated update and each group gradient, effectively resolving intra- and inner-batch gradient conflicts. Empirical results across various tasks and model scales demonstrate GRAIN's ability to consistently improve mean performance and reduce run-to-run variance without incurring additional training time or storage costs.
