if ((Y(i)*E(i) < -tol && alphas(i) < C) || (Y(i)*E(i) > tol && alphas(i) > 0)), % In practice, there are many heuristics one can use to select % the i and j. In this simplified code, we select them randomly. j = ceil(m * rand()); while j == i, % Make...

SVM约束因子测试---Matlab版本 1.约束因子 1.1 约束因子C 对于不可分的数据集,需要容忍一定错误率的存在。因此引入了约束因子C来权衡这个容忍度。 得到的优化问题为: 通过式子我们可以看到,但C足够大时,误差受到的关注度就会增大,这时SVM就会通过缩减间隔的方式来使这个误差减小。但支持向量机的"带宽"越小,容错率...

If one or more of these is in the matlab path, the program should just work. To add a custom SVM solution, refer to the code commentary in LinearClassifier. Code is extensively commented and documented. There are a number of outrageously obfuscated uses of arrayfun that may be of interest...

I am using Libsvm(3.17) software with MATLAB interface to classify my data which consist of 3 classes. i used code for traning , model = svmtrain(trainLabel, trainData, ' –s 0 –t 3 -c 1'); and for classification i used [predict_label, accuracy, dec_values] = svmpredict( test...
