Abstract

The invention provides a classifier generation method and a device, electronic equipment and a storage medium. The method comprises the steps of constructing a maximum mean value difference between asource domain and a target domain based on a sample of the source domain and a sample of the target domain; separating the maximum mean value difference between the source domain and the target domainto obtain a separated mean value difference; decomposing the optimization target according to the separated mean value difference to obtain a transformation matrix for the source domain; predicting the sample of the target domain based on the sample of the source domain, the label corresponding to the sample, the sample of the target domain and the transformation matrix for the source domain to obtain the label corresponding to the sample of the target domain; and generating a classifier corresponding to the target domain based on the samples of the source domain and the labels correspondingto the samples of the target domain. According to the method and the device, the maximum mean value difference related to large-scale calculation amount in transfer learning can be separated, so thatthe calculation complexity of transfer learning is reduced.

Description

technical field [0001] The invention relates to artificial intelligence technology, in particular to a method for generating a classifier, a method for classifying data to be classified, a device, electronic equipment and a storage medium. Background technique [0002] Artificial Intelligence (AI) is a comprehensive technology of computer science.
