| Challenge: | In high-precision tasks, vision language models suffer from Linguistic Priors Hallucination . |
| Approach: | They propose a training-free, inference-time intervention framework to mitigate this by integrating visual encoders with Large Language Model decoders. |
| Outcome: | The proposed framework reduces hallucination rates by 12% in long-context scenarios while maintaining robust generalization on standard benchmarks. |
