The forecast results of different seasons show that both the RBF neural network prediction model and the LSSVM prediction model wind speed prediction model can describe the trend of the original wind speed series, but the values of the LSSVM prediction model are more close to the original wind speed data.

Moreover, it is only necessary to compute the dot product of nonlinear mapping functions during the model construction and prediction phase of LSSVM. The result of this dot product of nonlinear mapping functions is the kernel function K(.).

There are a variety of methods for statistical downscaling [5], for example, the Delta Method (DM), Bias-Correction Method (BCM), Constructed Analogs Method (CAM), Localized Constructed Analogs Method (LOCA), Artificial Neural Networks (ANNs), Least Squares Support Vector Machines (LSSVM), nonparametric kernel regression (NKR) [8-10], and so forth.
So far, researchers have come up with many methods to build the soft sensing model, such as neural networks [5], the support vector machines (SVM) [6], partial least squares [7], and least squares support vector machine (LSSVM) [8]; these methods are aimed at specific problem.
