Changelog

Added

• Added ExcessMTL and ExcessMTLWeighting from Robust Multi-Task Learning with Excess Risks (ICML 2024). ExcessMTLWeighting is a stateful Weighting that maintains task weights across calls via an exponentiated gradient update driven by per-task excess risk estimates. The excess risk is approximated using an AdaGrad-style diagonal Hessian. An optional n_warmup_steps parameter controls how many forward calls collect gradient statistics before weight updates begin.
