TARAC: Mitigating Hallucination in LVLMs via Temporal Attention Real-time Accumulative Connection

Researchers introduce TARAC, a training-free framework that mitigates hallucinations in Large Vision-Language Models by dynamically preserving visual attention across generation steps. The method achieves significant improvements—reducing hallucinated content by 25.2% and boosting perception scores by 10.65—while adding only ~4% computational overhead, making it practical for real-world deployment.

Cross-Modal Attention Calibration for LVLM Hallucination Mitigation

Researchers propose Cross-Modal Attention Calibration (CMAC), a training-free method to reduce hallucinations in large vision-language models by addressing position bias and spurious correlations between visual and textual modalities. The approach combines an Inter-Modality Decoding module with contrastive mechanisms and a position calibration component to improve consistency between visual inputs and generated outputs.

Countering the Over-Reliance Trap: Mitigating Object Hallucination for LVLMs via a Self-Validation Framework

Researchers propose a Self-Validation Framework to address object hallucination in Large Vision Language Models (LVLMs), where models generate descriptions of non-existent objects in images. The training-free approach validates object existence through language-prior-free verification and achieves 65.6% improvement on benchmark metrics, suggesting a novel path to enhance LVLM reliability without additional training.
