| Challenge: | Large Language Models often produce unfaithful or factually incorrect outputs . masking retrieval heads can induce hallucinations, but decoding by contrast can reduce hallucinosity . |
| Approach: | They propose a training-free decoding strategy that contrasts the outputs of the base LLM and the masked LLM. |
| Outcome: | The proposed decoding strategy reduces hallucinations by contrasting the outputs of the base and masked LLMs. |
