摘要:

针对一类特定目标人脸识别中存在的问题, 提出一种基于Linex损失下BP神经网络的分类方法, 并给出了剑桥大学ORL人脸库上的测试结果. 实验结果表明, 所提出的方法能有效解决传统BP神经网络特定目标人脸识别中存在的问题.

关键词: Linex损失, BP神经网络, 收敛性, 人脸识别

Abstract:

Aiming at the specific objectives in face recognition, the authors proposed the BP neural network classification methods based on the Linex loss function, and presented the test results about face database of Cambridge as well. The image recognition experiments show that the traditional problems in specific target face recognition of BP neural network can be effectively solved the ORL by this method.

Key words: Linex loss function, BP neural network, convergence;  face recognition
