📰 ArXiv cs.AI

Researchers propose a training-free hallucination detector for large language models based on sample transform cost

advanced Published 25 Mar 2026
Action Steps
  1. Analyze the conditional distribution defined by an LLM with a prompt
  2. Estimate the complexity of the distribution as an indicator of hallucination
  3. Develop a sample transform cost-based detector to identify hallucinations without requiring training data
