What Should We Ask Next? Retrieval-Aware Question Learning under Partial Evidence

What changed

Researchers introduced RAVEL, a reinforcement learning framework that optimizes sequential question selection for interactive retrieval using rank feedback from the full retrieval loop.

Why you should care

Online reinforcement learning using rank feedback improves sequential question generation for interactive retrieval systems compared to static supervision.
