Abstract

The invention provides a data fitting method and device. The method includes the steps that data to be fitted are obtained; an SVM regression model and a kernel function are determined; according to the SVM regression model, the kernel function and the data to be fitted, a final fitting function is obtained through calculation; according to the final fitting function, the data to be fitted are fitted. Through the data fitting method and device, the accuracy of data fitting can be improved.

Description

Technical field [0001] The present invention relates to the technical field of data processing, in particular to a method and device for data fitting. Background technique [0002] Data fitting is a data processing method that uses a continuous curve to approximate or compare the functional relationship between the coordinates represented by the discrete point group on the plane. Through data fitting, discrete points can be described by functions, which is convenient for processing discrete points. [0003] In the prior art, a common data fitting method is to assume that the data to be fitted conforms to a certain distribution, such as a normal distribution, and then adjust the parameters of the assumed distribution function according to the data to be fitted until the requirements are met. [0004] It can be seen from the above description that in the prior art, the method of data fitting is to adjust the parameters of a hypothetical distribution. This method assumes a distribution...
