Benchmarking MLLMs via Cognitive Expected Scene Graph for Safety-Critical Visual Negation Understanding

True machine intelligence requires transcending passive pixel registration to master top-down functional reasoning over absent information via visual negation understanding. However, unconstrained visual negation paradigms remain overly open-ended, and pervasive affirmation bias causes both existing Multi-Modal Large L...

Combining Hierarchical Cognitive Process with Process Supervision for Interpretable Scene Safety Understanding

This work constructs a hierarchical cognitive safety structure, which motivates the development of a novel, high-quality scene safety understanding dataset based on multi-step reasoning with process labels, and introduces a modular and flexible process supervision framework that reflects the hierarchical nature of huma...
