L2RR learns a discrete sampling distribution over source prompts by optimizing a bilevel objective: maximizing accuracy on the held-out target dataset while penalizing those rollouts that provide little incremental learning information.

UnverifiedThe core idea of the L2RR method is that the target data owner can provide limited aggregate feedback (such as accuracy) from a small held-out target set without exposing target prompts or rollout trajectories.76% similarUnverifiedL2RR was empirically evaluated on six mathematical reasoning benchmarks and three model scales, and the results show that L2RR improves target-domain performance while also improving rollout efficiency.76% similarUnverifiedThe distillation step in RDR refers to using high-quality samples obtained through reinforcement learning exploration to supervise fine-tuning of a smaller or faster model, compressing the distribution learned in the reinforcement learning stage into an efficient inference path.74% similarUnverifiedIn RLHF and generative model fine-tuning, algorithm design should target the distribution-matching objective directly, exploiting the logarithmic convergence property of sampling regret to build a more efficient training pipeline.72% similarUnverifiedIn imitation learning, data quality and demonstration consistency directly determine the performance of the policy.70% similar
