In order to improve accuracy of dissolved oxygen prediction
radial basis function( RBF) neural network based on improved recursive least square algorithm is applied to predict the dissolved oxygen. Using K means clustering algorithm to choose the center of hidden layer units and improved recursive least square algorithm is used to optimize the weights of hidden layer to output layer of RBF neural network. Simulation results show that the proposed method has good nonlinear fitting ability and its prediction precision is higher than RBF neural network and RBF neural network based on recusive least square algorithm.
