Systematic Reward Gap Optimization for Mitigating VLM Hallucinations

arXiv — cs.CVTuesday, November 25, 2025 at 5:00:00 AM
  • A novel framework called Topic-level Preference Rewriting (TPR) has been introduced to systematically optimize reward gaps in Vision Language Models (VLMs), addressing the challenges of hallucinations during data curation. This method focuses on selectively replacing semantic topics within VLM responses to enhance the accuracy of generated outputs.
  • The development of TPR is significant as it aims to improve the reliability of VLMs, which are increasingly utilized in various applications, including image generation and natural language processing. By refining the reward gap configuration, TPR could lead to more coherent and contextually relevant outputs.
  • This advancement reflects a broader trend in AI research to enhance the performance of VLMs by addressing inherent limitations, such as biases and misalignments in data interpretation. The ongoing exploration of frameworks like Direct Preference Optimization and related methodologies highlights the industry's commitment to overcoming challenges in AI-generated content.
