Beyond Objective Expressivity: Geometry Preservation in Multimodal Contrastive Learning

Tillmann Rheude, Roland Eils, Benjamin Wild

Contrastive learning is increasingly moving toward settings with three or more modalities instead of image-text pairs. Yet, extending models from pairwise to higher-order multimoda…

Hidden in the Multiplicative Interaction: Uncovering Fragility in Multimodal Contrastive Learning

Tillmann Rheude, Stefan Hegselmann, Roland Eils +1

Contrastive learning has become a standard approach for unsupervised learning from paired data, as demonstrated by CLIP for image-text matching. However, many domains involve more…
