Intended uses & limitations

This model offers a valuable resource for research in explainable AI within educational technology. The model is trained with noisy response-level rationales. This makes them unsuitable for direct application in high-stakes assessments without additional verification.

Training and evaluation data

We trained and evaluated the model on the Synthetic Rationale data, which was generated from the Rationale MCTS data.

To extract scores from rationales, please use the jiazhengli/deberta-v3-large-Rationale-to-Score.
