| Abstract: | One of the important characteristic of feedforward neural networks is their ability to generalize the input/output behavior of functions based on a set of training examples.Yet many aspects of the problem of the improving generalization in feedforward neural networks have not been stuided well.The goal programmming method for neural network is proposed in this paper.Three enhancements are made in this method,those are:1)improvement of objective function;2)use of prior knowledge,3)decrease of the sensitivity of the neural network.Theoretical analysis and numerical example show that both generalization performance and the precision of forecasting of the neural networks are improved effectively. |
