Liu Hui, Yujie Song · 2018
Convolution neural network is a depth learning algorithm that can automatically extract features. A face recognition method based on convolution neural network and Fisher criterion is brought up to resolve the difficulty of poor property of convolution neural networks under small samples. First, a discriminant metric function is added in the cost function of the error and enhance the classification of the network. Then the face features by utilizing the modified convolution neural network are extracted. Finally, the advantage of support vector machine in the small sample, nonlinear and high dimension is used to classify the extracted features. The experimental results show that the face recognition algorithm which based on the Fisher neural network combined with SVM can achieve good results in the case of fewer samples.
