The BP neural network classification method under Linex loss function and the application to face recognition

Within the statistical decision theory framework, This paper focuses on specific objectives in face recognition, and proposes the BP neural network classification methods which is under the Linex loss function, and proves that the convergence of BP neural network under the Linex loss function. The image recognition experiments with the ORL face database in Cambridge show that this method can effectively solve the traditional problems in specific target face recognition of BP neural network.
