In this episode, we discuss Why Language Models Hallucinate by The authors of the paper are:
- Adam Tauman Kalai
- Ofir Nachum
- Santosh S. Vempala
- Edwin Zhang. The paper explains that hallucinations in large language models arise because training and evaluation reward guessing over admitting uncertainty, framing the issue as errors in binary classification. It shows that models become incentivized to produce plausible but incorrect answers to perform well on benchmarks. The authors propose that addressing hallucinations requires changing how benchmarks are scored, promoting more trustworthy AI by discouraging penalization of uncertain responses.
In this episode, we discuss Is Chain-of-Thought Reasoning of LLMs a Mirage? A Data Distribution Lens by Chengshuai Zhao, Zhen Tan, Pingchuan Ma, Dawei Li, Bohan Jiang, Yancheng Wang, Yingzhen Yang, Huan Liu. The paper investigates Chain-of-Thought (CoT) reasoning in large language models, revealing it may not reflect true inferential processes but rather learned patterns tied to training data distributions. Using a controlled environment called DataAlchemy, the authors show CoT reasoning breaks down when models face out-of-distribution tasks, lengths, or formats. This highlights the limitations of CoT prompting and the challenge of achieving authentic, generalizable reasoning in LLMs.
