Towards Faithful and Robust LLM Specialists for Evidence-Based Question-Answering

The paper introduces an approach to improve Large Language Models (LLMs) for evidence-based question-answering by fine-tuning them on synthetic data enhanced with quality filters. This method aims to increase the models’ faithfulness and robustness.

Objectives and Expectations

The research targets enhancing LLMs’ ability to accurately source and represent information from evidence in QA applications. By utilizing high-quality synthetic data for fine-tuning, it seeks to address existing model limitations.

Methodology

Creating synthetic datasets (SynSciQA, SynSciQA+, SynSciQA++) and applying quality filters forms the core of the methodology, aimed at improving data quality for LLM fine-tuning.

Results and Findings

Fine-tuning on these enhanced datasets significantly boosts LLM performance in evidence-based QA, demonstrating the critical role of data quality.

Comparison with Previous Research

This work builds on existing LLM fine-tuning techniques, emphasizing the unique contribution of synthetic data quality improvement to model performance.

Future Tasks

Further research will focus on expanding the synthetic dataset, refining quality filters, and applying these models in practical QA settings.

Practical Takeaways

  • Quality-filtered synthetic data is key to enhancing LLM performance in evidence-based QA.
  • This approach offers a scalable method for improving LLM robustness and reliability.
