Abstract

The invention relates to a distillation learning method and device, computer equipment and a storage medium. The method comprises the following steps: respectively inputting a target image into a teacher network and a student network to obtain a teacher feature map output by the teacher network and a student feature map output by the student network; performing channel matching on the teacher feature map and the student feature map, and obtaining a target loss value between the teacher feature map and the student feature map according to a matching result; and adjusting parameters in the student network according to the target loss value to obtain a target student network. By adopting the method, the distillation learning effect of the student network on the teacher network can be improved, and the performance difference between the student network and the teacher network is reduced.

Description

technical field [0001] The present application relates to the technical field of machine learning, in particular to a distillation learning method, device, computer equipment and storage medium. Background technique [0002] With the development of machine learning technology, distillation learning technology has emerged. Distillation learning uses migration learning, using the output of a pre-trained complex network model (teacher model) as a supervisory signal to train another simple network model. (Student network, Student model) to obtain a student network with a simplified structure and low computational complexity, while having the knowledge of the teacher network. [0003] In the traditional technology, most of them are carried out from the three aspects of pixel-level distillation, relational distillation and discriminator-based global distillation, but the distillation learning effect is poor, and the performance of the obtained student network and the teacher netwo...
