Cross-modal retrieval with image-text, sketch-image, etc. are gaining increasing importance due to abundance of data from multiple modalities, and applications like e-commerce, security, etc. In [1], we develop a novel approach which utilizes few labeled and remaining unlabeled data for this task, thus reducing manual intervention significantly. In [2], we address the problem of retrieving previously unseen data [2], since new categories are discovered dynamically in real-world.
