We propose a hybrid method for forecasting the wind speed. The wind speed datais first decomposed into intrinsic mode functions IMFs with empirical mode decomposition. Basedon the partial autocorrelation factor of the individual IMFs, adaptive methods are thenemployed for the prediction of IMFs. Least squares-support vector machines are employed for IMFswith weak correlation factor, and autoregressive model with Kalman filter is employed for IMFs withhigh correlation factor. Multistep prediction with the proposed hybrid method resulted in improvedforecasting. Results with wind speed data show that the proposed method provides better forecastingcompared to the existing methods.
