Researchers have introduced Minimal Intervention Reinforcement Learning (MInTRL), a novel approach to enhance on-policy reinforcement learning. MInTRL expands exploration by incorporating sparse, local interventions into existing on-policy rollouts. This method uses a judge-intervention policy to correct erroneous outputs and a sequence-level advantage-regression objective for training, avoiding the need for importance sampling. Experiments across math and code benchmarks demonstrate that MInTRL consistently outperforms standard on-policy and off-policy baselines, establishing minimal intervention as a viable paradigm for improving RL.
