LIBSVM在MATLAB中的使用

下载

• libsvm库下载：http://www.csie.ntu.edu.tw/~cjlin/libsvm/
• 数据集下载：http://www.csie.ntu.edu.tw/~cjlin/libsvmtools/datasets/

配置

设置path：File->set path ->add with subfolders->加入libsvm-3.x文件夹的路径

使用

>> [label instance] = libsvmread('heart_scale');>> svmStruct = svmtrain(label, instance);*optimization finished, #iter = 162nu = 0.431029obj = -100.877288, rho = 0.424462nSV = 132, nBSV = 107Total nSV = 132>> [predict_label,accuracy] = svmpredict(label, instance, svmStruct);Accuracy = 86.6667% (234/270) (classification)
