| Abstract: | To solve the on-line learning for neural networks, the neural network is taken as a nonlinear system with known structure, and the learning of weight parameter is taken as a parameter estimation for nonlinear system.Then,the on-line projection algorithm of the forward neural network is presented by the projection algorithm of nonlinear system parameter estimation based on a new estimation criterion.The global convergence is proved in theory, and the physical meaning and changing area of parameters are discu... |
