Signal Reshaping for GRPO in Weak-Feedback Agentic Code Repair
arXiv CS.AI

ArXi:2605.07276v1 Announce Type: new Code-agent RL often receives weak feedback: rollout-time signals are reliable and executable, but capture only necessary or surface conditions for task success rather than the target semantic predicate. Using agentic compile-fix as the setting, we study signal reshaping for standard GRPO under such feedback.
