Abstract
The main objective of this paper is to utilize standard Support Vector Regression, Least Squares Support Vector Regression, and compare these techniques to traditional regression and a rain rate formula that meteorologists use, to facilitate rainfall estimation and rainfall detection. Ground truth rainfall data are necessary to apply intelligent systems techniques. A unique source of such data is the Oklahoma Mesonet. Recently, with the advent of a national network of advanced radars, massive archived data sets are available for data mining. The reflectivity measurements from the radar are used as inputs for the techniques tested. The results show that SVR and LS-SVR are better in terms of generalization error than traditional regression and rain rate formula used in meteorology for both rainfall estimation and rainfall detection. Moreover, LS-SVR shows a better performance than SVR for rainfall estimation and vice versa for rainfall detection.
