Space Data Fitting Based on the Support Vector Machine-SVM

FENG Yang-min,LIANG Jing(School of Geology Engineering and Geomatics,Chang'an University,Xi'an,Shaanxi,710054)  
Space data fitting is used to illustrate the relationship of them by the collection of spatial information and the construction of rational data processing model.The usage of support vector machine in space data fitting is based on the minimal risk.Taking the advantage of Taylor formula,the second fitting of the SVM residual error is proposed in order to improve the fitting accuracy when fitting the undulating space data.The validity of the thought of the paper is demonstrated by an exampe.
