New benchmark MotionHalluc reveals kinematic hallucinations in LLMs

Researchers have introduced MotionHalluc, a new benchmark designed to identify and diagnose kinematic hallucinations in large multimodal models. This benchmark evaluates motion hallucinations across directional, attributional, and temporal dimensions using 1540 fine-grained questions over 553 video pairs. The study found that current state-of-the-art models are highly susceptible to these hallucinations. To combat this, the team proposed Perceive-Parse-Verify (PPV), a training-free method that injects explicit quantitative measurements into the reasoning process, leading to an average performance gain of 10.6% across tested models.

IMPACT Highlights a new vulnerability in multimodal models, potentially guiding future research towards more robust motion reasoning capabilities.

    MotionHalluc: Diagnosing Kinematic Hallucinations in Fine-Grained Motion Reasoning

    Motion instruction generation in cross-video comparison aims to produce corrective feedback that describes the differences between a query and a reference motion. However, existing models often generate instructions that exhibit motion hallucinations, failing to reflect actual ki…
