Xu Cui SVM regression with libsvm. SVM is mostly commonly used for binary classifications. But one branch of SVM, SVM regression or SVR, is able to fit a continuous function to data. This is particularly useful when the predicted variable is continuous. Here I tried some very simple cases using libsvm matlab package 1. Feature 1. D, use 1st half to train, 2nd half to test. The fitting is pretty good. D2. Still 1. D, but apparently the data is nonlinear. So I use nonlinear SVR radial basis. The fitting is good. D3.

Wolfram Mathematica usually termed Mathematica, Mathematica software suite is a mathematical symbolic computation program, sometimes termed a computer algebra. Here I tried feature space with up to 1. For linear SVR blue, the number of dimension doesnt affect the correlation much. One property of SVR I like is that, when two features are similar i. This is in contrast with winner take all property of general linear model GLM. This property is desired in brain imaging analysis neighbor voxels have highly correlated signals and you want them to have similar weights. About performance If different features have different scales, then normalization of data will improve the speed of libsvm. Also, the cost parameter c also affects the speed. The larger c is, the slower libsvm is. For the simulated data I used, the parameters dont affect the accuracy. Mat. Lab code testsvr. The normalization function copy and save it into normalize.
