Math Shepherd Mistral 7b Rl

🚀 Mistral-7b-MetaMATH with Step-by-Step PPO

This project fine-tunes the Mistral-7b model using step-by-step PPO in Math-Shepherd, aiming to improve performance on math problems.

🚀 Quick Start

Model Information

• Base model: mistral-7b-sft
• PRM: math-shepherd-mistral-7b-prm
• PPO training set: Questions in MetaMATH [1]

Performance

Input Format

The input should only contain the math problem, without any system prompt. For example:

Janet\u2019s ducks lay 16 eggs per day. She eats three for breakfast every morning and bakes muffins for her friends every day with four. She sells the remainder at the farmers' market daily for $2 per fresh duck egg. How much in dollars does she make every day at the farmers' market?

Output Format

The output should be step-by-step solutions with a special step tag ки. For example:

Step 1: Janet's ducks lay 16 eggs per day. ки\nStep 2: She eats three for breakfast every morning, so she has 16 - 3 = 13 eggs left. ки\nStep 3: She bakes muffins for her friends every day with four eggs, so she has 13 - 4 = 9 eggs left. ки\nStep 4: She sells the remainder at the farmers' market daily for $2 per fresh duck egg, so she makes 9 * $2 = $18 every day at the farmers' market. The answer is: 18 ки
