Modal hash network training method and device, equipment, medium and program product

The invention discloses a modal Hash network training method and device, equipment, a medium and a program product, and belongs to the field of artificial intelligence. The training method comprises the following steps: acquiring a sample data set; performing mapping processing on the sample data by adopting at least two modal hash networks corresponding to the modal of the sample data to obtain at least two modal hash codes corresponding to the sample data; obtaining each type of hash code corresponding to the type information of the sample data set; the category hash code is obtained by mapping category information based on a trained data perception proxy network and performing data perception on sample data, and the data perception refers to perception of feature information of the sample data; and based on the at least two modal Hash codes and the various types of Hash codes, respectively training model parameters of the at least two modal Hash networks to obtain at least two trained modal Hash networks.
