in validation phase obtained by W-SVM model is 16.02 W/m
2
(12.53); which is
higher than that of the traditional SVMmodel with
สต
-SVR and linear kernel function.
The performance ef
ciency of W-SVM model in the solar radiation modelling is
2.05 % lower than that of W-ANFIS model for the training data and the corre-
sponding value for validation data is 7.13 % lower.
The observed and estimated daily solar radiation values of W-ANFIS model for
the training data are given in Fig.
