外文摘要：A kind of flexible neural network of compound orthogonal type with a unipolar sigmoid function was presented,and a parameter and its learning algorithm was given oriented to existing insufficiency of the general compound orthogonal neural network. The flexibly orthogonal neural network not only expands the model identification ability and learning adaptation of the neural network, but also has a simple algorithm, a high-speed convergence of learning process, and excellent characteristics in the linear and nonlinear accurate approximation. The application examples with model identification were given. The simulation results show the learning algorithm in the flexible neural network was effective. Compared with general compound orthogonal neural networks, the performance of this kind of flexible neural network was improved.
