UnverifiedGRPO and its variants often encounter issues such as training collapse, reward oscillation, and late-stage performance degradation in actual training.70% similarUnverifiedThe core feature of GRPO is that it generates a set of candidate outputs for the same input and computes advantage values from the relative quality of this set of outputs, without needing to train an independent critic/value network as PPO does.69% 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.69% 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.69% similarUnverifiedUsing GRPO reinforcement learning on Zork I achieves near-perfect budget adherence and generalizes to new budget levels not seen during training.65% similar
