Abstract: Abstract: Most of the current cross-modal Hashing methods can only be trained when fully paired instances are provided, and are not suitable for a large number of unpaired data in the real world. In order to solve this problem, an unpaired cross-modal Hashing method for Web news data is proposted. Firstly, a feature fusion network is constructed to process the unpaired training data, the modal information is supplemented and improved, and the adversarial loss is used to strengthen the common representation of learning. Secondly, the affinity matrix optimizes the feature distribution of samples and the generated binary codes, so that the semantic relationship between samples is more explicit. Finally, we add a class prediction loss to enhance the discrimination ability of binary codes. Experiments on real network news datasets with paired scenes and unpaired scenes respectively, the results show that the proposed method can be extended to practical applications.
