Problems solved by technology

However, the pruning of the network is carried out on the already trained network, and it will not be restored after pruning, so the problem of capacity reduction still exists. Therefore, it is studied how to effectively combine the two types of methods more scientifically to achieve More efficient compression and acceleration effects are necessary

Abstract

The invention discloses a convolutional neural network channel self-selection compression and acceleration method based on knowledge migration. The method comprises the following steps: S1, extractingmigration guidance knowledge from a trained complex convolutional neural network CN1; S2, setting randomly initialized coefficient masks for all convolutional layer channels of the target convolutional neural network ON1; S3, setting the output of each channel of the target network as a product of the original output of the channel and the corresponding coefficient mask; and S4, optimizing the target network under the guidance of the migration guidance knowledge, carrying out channel soft cutting according to the coefficient mask, and carrying out channel hard cutting until the target networkconverges. According to the method, the network can automatically select the channel to be cut off, manual selection operation is omitted, the expression capacity of the network is reserved and the generalization performance is improved through soft cut-off operation and a knowledge migration method, so that a higher compression ratio and a higher acceleration ratio are realized.
