UnverifiedCompared with standard GRPO training, ReTerm-GRPO achieves more stable and higher recovery rates across a variety of different error categories.73% similarVerifiedTraditional RLHF requires first training a reward model and then optimizing with reinforcement learning algorithms such as PPO, making the process complex and unstable.73% similarVerifiedCompared to PPO, GRPO eliminates the value network (Critic) and directly compares rewards among samples within a group to estimate the advantage function, significantly reducing training computation costs.73% similarVerifiedGRPO samples multiple responses to the same question and computes relative rewards within the group to estimate the baseline, eliminating the overhead of training a separate value network.73% similarUnverifiedSteering Agent is trained with joint reinforcement learning optimization, and its objective function combines a pairwise ranking objective and Group Relative Policy Optimization (GRPO).71% similar
