RE-TRIANGLE: Does TRIANGLE Enable Multimodal Alignment Beyond Cosine Similarity in Retrieval?
A reproducibility study of the TRIANGLE framework reveals that geometric alignment on hyperspheres improves multimodal retrieval beyond traditional pairwise approaches, achieving up to 8.7 point gains in zero-shot settings. However, researchers identified critical optimization instabilities when jointly training with data-text matching loss and reduced cross-dataset generalization with fine-tuning, suggesting the method's benefits are context-dependent rather than universally applicable.
