摘要
Abstract
A forecasting model of air pollutant concentration in urban areas was established in combination with a method of wavelet transform and support vector machine. First, series of air pollutant concentrations were decomposed into several different frequency decomposed series by the wavelet decomposition and reconstruction. Secondly, the decomposed series were predicted with different independent prediction models. Finally, the predicted results from every decomposition series were integrated as the final prediction result of the concentration The results show that the forecast accuracy is better than the RBF neural network model and the general support vector machines.关键词
