🤔 Original Problem:

LLMs struggle with complex physics reasoning despite showing strong capabilities in text-based tasks. Current approaches using prompt engineering and retrieval augmentation don't fully address reasoning limitations.

-----

🔧 Solution in this Paper:

→ The paper introduces Reinforcement Learning with Human and AI Feedback (RLHAIF) to improve LLM performance on physics questions

→ RLHAIF combines human and AI feedback to create high-quality preference datasets while minimizing human supervision

→ The solution evaluates multiple reinforcement learning methods including PPO, DPO, and Remax optimization

→ The approach uses the PhyQA dataset containing challenging physics problems from high school textbooks

→ The system incorporates carefully selected few-shot examples of human-ranked physics answers to refine preference data

-----

💡 Key Insights:

→ Combining human and AI feedback creates more reliable and logically sound outputs

→ PPO outperforms other RL methods for physics reasoning tasks

→ Model struggles most with arithmetic calculations (35% of errors)

→ Problem deduction errors contribute 10% of total errors

-----

📊 Results:

→ Mistral-PPO achieved 58.67 METEOR score and 0.74 Reasoning score

→ Model demonstrates 64% prediction accuracy on test sets

→ Achieves Sharpe ratio of 2.21 on test portfolio
