How to select best parameters for SVM linear kernel type

I perform a classification of two labels using libsvm. But I don't get good results for the default parameters of SVM kernel type = linear. Can any one please tell me a way to find best parameters for SVM linear kernel type

Solution

  • The linear kernel depends on the C parameter.

    You could perform a grid-search for this parameter in order to find the 'best' matching one for your given dataset.

    For weka the procedure is described here.
