advanced Published 5 Jun 2026
Action Steps
  1. Implement RREDCoT to redistribute rewards at the segment level
  2. Use Reinforcement Learning fine-tuning to train reasoning language models
  3. Apply the Group Relative Policy Optimization algorithm or its modifications
  4. Evaluate the performance of the model using the redistributed rewards
  5. Fine-tune the model to optimize its Chain-of-Thought traces
