摘要
Abstract
According to the characteristics that the conventional model of dam safety early-warning is sensitive to the missing data and the forecast accuracy is prone to be affected by other factors, a model combing the improved PSO algorithm and SVM theory was proposed, which seeks the optimal parameters of SVM model through PSO algorithm. Meanwhile, the convergence de-gree is introduced and the inertia weight factor and study factor are optimized to avoid the premature convergence of PSO, so the global searching ability is improved. The establishing process of the model was introduced and the forecast accuracy was verified by actual monitoring data. With the analysis of the example, it is proved that the improved model is superior to the conventional model, and the application range of PSO algorithm is extended.关键词
