Deep Learning is all about Gradient Based Methods. Particularly, learning deep hash functions has greatly improved the retrieval performance, typically under the semantic supervision. We focus on investigating interpretable and scalable techniques for doing so. Combinatorial settings raise new technical challenges because the optimization problem is discrete. Hence, utilizing supervised information to directly guide discrete (binary) coding procedure can avoid sub-optimal solution and improve the accuracy. levels representing more abstract concepts. the field of deep learning has lead to groundbreaking performance in many applications such as computer vision, speech understanding, natural language processing, and computational biology.
