Do VLMs Perceive or Recall? Probing Visual Perception vs. Memory with Classic Visual Illusions

CVPR 2026

Large Vision-Language Models (VLMs) often answer classic visual illusions "correctly" on original images, yet persist with the same responses when illusion factors are inverted, even though the visual change is obvious to humans. This raises a fundamental question: do VLMs perceive visual changes or

Data or Language Supervision: What Makes CLIP Better than DINO?

EMNLP 2025

CLIP outperforms self-supervised models like DINO as vision encoders for vision-language models (VLMs), but it remains unclear whether this advantage stems from CLIP’s language supervision or its much larger training data. To disentangle these factors, we pre-train CLIP and DINO under controlled set
