Prediction of stream based on discrete differential evolution algorithm and on-line least squares support vector machine

According to the online least square support vector machine (SVM) parameters optimization and the nonlinear of steam prediction, this paper puts forward a kind of optimization prediction algorithm based on differential evolution algorithm combined with the online least square support vector machine. By Using this algorithm to predict steam production, the result shows that it can provide the decision-making basis for steam production and real-time operation.
