Reasoning-Augmented Representations for Multimodal Retrieval

Jianrui Zhang, Anirudh Sundara Rajan, Brandon Han +3

Universal Multimodal Retrieval (UMR) seeks any-to-any search across text and vision, yet modern embedding models remain brittle when queries require latent reasoning (e.g., resolvi…

CoAPT: Context Attribute words for Prompt Tuning

Gun Lee, Subin An, Sungyong Baik +1

We propose a novel prompt tuning method called CoAPT(Context Attribute words in Prompt Tuning) for few/zero-shot image classification. The core motivation is that attributes are de…
