Abstract： With the development of information technology, face recognition is used more and more in payment, work and security system. In the edge computing system, in order to deal with the speed, we usually choose a smaller neural network for face recognition, which may cause the recognition rate is not very high. And in practical applications, most of them can recognize the face with high image quality, but the recognition rate is not very high for the face which is greatly affected by the light and has great changes in expression and posture. Therefore, this paper chooses the SqueezeNet lightweight network, which has a small number of layers and can be well used in edge computing system. The method of preprocessing is used to preprocess the image, and then the loss function of SqueezeNet network and the residual learning method of ResNet network are improved. Finally, through the test of LFW and IJB-A data set, it is concluded that the research method in this paper can significantly improve the recognition rate.
