Hallucination Evaluation Benchmark

Hallucination evaluation benchmarks aim to systematically assess the tendency of large language models (LLMs) to generate factually incorrect or unsupported information. Current research focuses on developing comprehensive benchmarks encompassing diverse tasks and modalities (text, image, audio-visual), employing various techniques like contrastive learning on internal LLM states and probabilistic frameworks based on belief propagation to detect hallucinations. These benchmarks are crucial for advancing LLM development by providing standardized metrics to evaluate and improve model reliability, ultimately impacting the safe and effective deployment of LLMs in real-world applications.
