The Phenomenon of Hallucination in Language Models
This chapter explores the concept of hallucination in Language Models (LLMs), originated in image captioning literature and extended to tasks like abstractive summarization. It discusses the need for more precision and rigor in understanding the failure modes of LLMs, touching on the potential solutions such as uncertainty quantification. The chapter also delves into techniques for assessing uncertainty, confidence thresholds, and the potential impact of LLMs.
