P\textsuperscript{2}-DPO: Grounding Hallucination in Perceptual Processing via Calibration Direct Preference Optimization
arXiv:2606.03376v1 Announce Type: cross Abstract: Hallucination has recently garnered significant research attention in Large Vision-Language Models (LVLMs). Direct Preference Optimization (DPO) aims to learn directly from the corrected preferences provided by humans, thereby addressing the hallucination issue. Despite its success, this paradigm has yet to specifically target the perceptual bottleneck in attended regions or address insufficient Visual Robustness against image degradation. Furthermore, existing preference pairs are often vision-agnostic and their inherently off-policy nature li
The proliferation of Large Vision-Language Models (LVLMs) has amplified the challenge of hallucination, driving urgent research into advanced optimization techniques like DPO to enhance their reliability.
Improving the perceptual accuracy and robustness of LVLMs directly addresses a major limitation preventing their broader adoption in critical applications, impacting trust and utility in AI systems.
New methods using direct preference optimization to ground hallucination in perceptual processing could lead to more reliable and trustworthy multimodal AI, specifically addressing visual interpretation and robustness.
