Researchers from OpenGVLab, Shanghai AI Laboratory and Tsinghua University developed ASMv2, a Multi-modal Large Language Model designed to improve object relation comprehension and grounding in images, reducing factual inconsistencies. The model demonstrates superior performance on newly introduced relation-specific benchmarks and achieves state-of-the-art results across general vision-language and region-level tasks.

Key insights

  • Explicitly grounding predicates to specific subject and object bounding boxes is crucial for MLLMs to learn fine-grained visual relationships and mitigate relation hallucination.
  • High-quality, instruction-tuned relation conversation data, even generated by powerful multimodal models like GPT-4V, can effectively train MLLMs for complex relation comprehension.
  • A two-stage training approach, combining general image-level vision-language alignment with specific region-level grounding and relation comprehension, is effective for building models with broad and deep visual understanding.
