Performance Prediction of Commercial Concrete Based on RBF Neural Network

On the basis of comprehensive analysis,a prediction model of RBF network with 9 input vectors and 1 output vectors is set up to express the complex nonlinear relationship of performance index and their influencing factors.In contrast,the prediction results from three different input models of RBF network are compared with each other,and also compared with that of BP network.As a result,the RBF network model mentioned in this paper has high precision and good generalization capacity and can become a new effective prediction method.
