First-order policy gradient methods can achieve minimax-optimal sample complexity for general parametric policies without restrictive assumptions or second-order operations.

The clinical usability study showed that lung expert and nonexpert physicians improved their prediction with the explainable AI (XAI) ML CB-only based tool, and Although multimodal integration with MLEF (CB+CT+DP) was associated with higher performance, its incremental benefit remains uncertain, not translated in TEST and EXVAL.
