DirMixE: Harnessing Test Agnostic Long-tail Recognition with Hierarchical Label Vartiations

Researchers introduce DirMixE, a new machine learning approach for handling test-agnostic long-tail recognition problems where test data distributions are unknown and imbalanced. The method uses a hierarchical Mixture-of-Expert strategy with Dirichlet meta-distributions and includes a Latent Skill Finetuning framework for efficient parameter tuning of foundation models.
