SourceVOILA: Evaluation of MLLMs For Perceptual Understanding and Analogical Reasoning
An ablation study on GPT-4o using VOILA-WD with L2M prompting provided ground-truth image descriptions at phase 2, after which GPT-4o identified relationships at 97% accuracy. However, when ground-truth relationships were provided at phase 3, GPT-4o's accuracy on applying those relationships to the third image dropped to 17%, well below the 71% human baseline. A complementary ablation on VOILA-ND showed GPT-4o achieves 22% accuracy with three sequential images but 49% with text descriptions of the same images, indicating a modality gap in visual relational reasoning.
