Contrastive vision-language learning with paraphrasing and negation

arXiv:2511.16527v2 Announce Type: replace-cross Abstract: Contrastive vision-language models continue to be the dominant approach for image-text retrieval. Contrastive Language-Image Pre-training (CLIP) trains two neural networks to align their image and text embeddings in a shared latent space. As a challenging case-study for neurosymbolic AI, recent results evaluating CLIP on negated or paraphrased text have shown mixed performance as these are difficult to define formally for text data. Negation produces the opposite meaning using various possible but small lexical changes. Paraphrasing may

Why this matters
Why now

The continuous evolution of vision-language models like CLIP demands addressing their limitations in nuanced text understanding, a critical step for more robust AI applications.

Why it’s important

Improving AI's ability to handle linguistic subtleties like negation and paraphrasing is central to developing more reliable and human-like AI systems, impacting fields from search to autonomous systems.

What changes

This research suggests a future where vision-language models can better interpret complex human language, leading to more accurate and context-aware AI interactions.
