ReasonEval-7B

ReasonEval-7B Model Card

Model Description

ReasonEval-7B is a 7B parameter decoder-only language model fine-tuned from WizardMath-7B-V1.1. Given a mathematical problem and the solution, ReasonEval-7B assesses the problem-solving process in a step-by-step format from the following perspectives:

• Validity: The step contains no mistakes in calculation and logic.
• Redundancy: The step lacks utility in solving the problem but is still valid.

With ReasonEval, you can

• 📏 quantify the quality of reasoning steps free of human or close-source models.

• 🤖 find the potential invalid or redundant steps in the solutions even with the correct results.

• 🛠️ select high-quality training data for downstream tasks (e.g., fine-tuning).

Model Details

• Model type: ReasonEval-7B's architecture is identical to WizardMath-7B-V1.1, except that the classification head for next-token prediction is replaced with a classification head for outputting the possibilities of each class of reasong steps.
