Researchers have introduced SAGE (Spectral-Aware Gradient-Aligned Exploration), a novel method for multi-distribution learning that addresses limitations in existing approaches. Unlike methods that focus solely on flatness or gradient alignment, SAGE considers both geometric properties of the loss landscape. The method decomposes excess risk into alignment and curvature terms, showing that neither property alone guarantees optimal performance. Experiments on domain-generalization and multi-task learning benchmarks demonstrate that SAGE achieves new state-of-the-art results on DomainBed and improves upon existing multi-task learning solvers.
