Reward Mixology: Crafting Hybrid Signals for Reinforcement Learning Driven In-Context Learning (2025.findings-emnlp)

Copied to clipboard

Challenge: Existing methods for in-context learning (ICL) performance rely on quality and ordering of demonstrations.
Approach: They propose a method that models iterative demonstration selection as a Markov Decision Process and craft hybrid reward signals.
Outcome: The proposed method combines outcome-based accuracy signals with process-oriented signals like stepwise influence and label entropy improvement.
