Can VLMs Reason Robustly? A Neuro-Symbolic Investigation

arXiv:2603.23867v2 Announce Type: replace Abstract: Vision-Language Models (VLMs) have been applied to a wide range of reasoning tasks, yet it remains unclear whether they can reason robustly under distribution shifts. In this paper, we study covariate shifts in which the perceptual input distribution changes while the underlying prediction rules do not. To investigate this question, we consider visual deductive reasoning tasks, where a model is required to answer a query given an image and logical rules defined over the object concepts in the image. Empirically, we find that VLMs fine-tuned t

Why this matters
Why now

The rapid advancement and widespread application of Vision-Language Models (VLMs) necessitate a deeper understanding of their reasoning capabilities and robustness, especially as they move into more critical applications.

Why it’s important

Understanding the limits of VLM robustness under distribution shifts is crucial for developing reliable and trustworthy AI systems, impacting their deployment in safety-critical or real-world variable environments.

What changes

This research provides empirical evidence questioning the robust reasoning abilities of current VLMs, pushing the field towards more resilient neuro-symbolic AI architectures rather than purely data-driven approaches.
