UnverifiedWaypoint-OPD relies on being able to access the teacher's intermediate checkpoints, so it is not applicable to scenarios where only the final model is available.63% similarUnverifiedOPRD's design idea is to give reminder signals during training and completely remove the reminders at inference time, so that the student model ultimately learns to complete long-horizon tasks independently without reminders.61% similarUnverifiedSeTPO introduces teacher signals only for low-reward trajectories, uses reverse KL divergence to derive token-level teacher feedback, and incorporates it into the policy advantage function.60% similar
