Abstract

The invention discloses an image recognition method based on a depth neural network model. The target image is inputted into the target model which is obtained by pruning the depth neural network model with the channel representation ability. Using the auxiliary classifier in the target model to classify the target image, the recognition results are obtained. Because the target model of target image recognition is a pruned model based on the channel representation ability, the computational cost of target image recognition can be greatly reduced. The invention also discloses an image recognition device, a device and a readable storage medium based on a depth neural network model, which have corresponding technical effects.

Description

Technical field [0001] The present invention relates to the technical field of intelligent recognition, in particular to an image recognition method, device, equipment and readable storage medium based on a deep neural network model. Background technique [0002] At present, in image classification and recognition such as image classification and face recognition, deep neural network models are very important. However, the deep neural network has the characteristics of many parameters and large amount of calculation, resulting in a large amount of memory requirements and computational burden, making it difficult to apply the deep neural network model to hardware devices such as mobile phones with limited storage and computing resources.
