Learning with Multi-modal Gradient Attention for Explainable Composed Image Retrieval

no code implementations31 Aug 2023 Prateksha Udhayanan, Srikrishna Karanam, Balaji Vasan Srinivasan

To this end, our key novelty is a new gradient-attention-based learning objective that explicitly forces the model to focus on the local regions of interest being modified in each retrieval step.

CoPL: Contextual Prompt Learning for Vision-Language Understanding

no code implementations3 Jul 2023 Koustava Goswami, Srikrishna Karanam, Prateksha Udhayanan, K J Joseph, Balaji Vasan Srinivasan

Our key innovations over earlier works include using local image features as part of the prompt learning process, and more crucially, learning to weight these prompts based on local features that are appropriate for the task at hand.
