RLER trains reasoning policies on unlabeled queries by combining reward judgments from multiple policies, calibrated ensemble confidence, and selective rollout updates, then merging the policies for deployment. On DAPO-MATH-17K with Qwen2.5-Math-7B, it reaches 37.5 Avg@8 across six math benchmarks, above Co-rewarding’s 35.3 but below label-based RLVR’s 38.9 under these tested conditions.
