Hallucination Detection in LLMs Using Spectral Features of Attention Maps (2025.emnlp-main)
Copied to clipboard
| Challenge: | Large Language Models (LLMs) have demonstrated remarkable performance across tasks but remain prone to hallucinations. |
| Approach: | They propose a method that uses attention maps to detect hallucinations . they propose to use top-k eigenvalues of the attention maps as input to probes . |
| Outcome: | The proposed method achieves state-of-the-art hallucination detection performance among attention-based methods. |
