Model Details

xFinder-llama38it is a model specifically designed for key answer extraction in large language models (LLMs). It is trained by fine-tuning Llama3-8B-Instruct.

• Developed by: IAAR
• Fine-tuned from Model: Llama3-8B-Instruct

Model Sources

• Repository: https://github.com/IAAR-Shanghai/xFinder
• Paper: https://openreview.net/forum?id=7UqQJUKaLM

Uses

xFinder is primarily used to enhance the evaluation of LLMs by accurately extracting key answers from their outputs. It addresses the limitations of traditional regular expression (RegEx)-based extraction methods, which often fail to handle the diverse and complex outputs generated by LLMs. xFinder improves the reliability of model assessments across various tasks.

Training Details

xFinder-llama38it is fine-tuned from Llama3-8B-Instruct. The training data consists of approximately 26.9K samples from the Key Answer Finder (KAF) dataset. This dataset is designed to enhance the accuracy and robustness of key answer extraction and includes a variety of tasks. It has been meticulously annotated by GPT-4 and human experts to ensure high-quality training and evaluation. For more details, see this paper and try it with code.

Evaluation

xFinder is evaluated on the fully human-annotated test and generalization sets of the KAF dataset. The results demonstrate significant improvements in extraction accuracy and robustness compared to traditional methods. For more details, please refer to the paper and try it out using the provided code.
