RefChecker – Hallucination Detection
Fine-grained detection of factual errors in large language model outputs.
- Duration: August 2023 – November 2023
- Technologies: Python, PyTorch, NLP, LLMs
Highlights
- Engineered an automated hallucination-detection system that identifies factual errors in LLM outputs at the sub-sentence level using contextual entailment.
- Achieved 90% precision on benchmark datasets with a modular architecture combining extractor, checker, and aggregator components.
