The default kernel available in SVM Classification is rbf.
Can someone please suggest how can I use the Linear kernel with the SVM. Is there any way i can pass this as a parameter ?
Kernel parameter is not exposed for SVM algorithm (set to rbf) in MLTK but if you want to use Linear Kernel, you can implement that algorithm into MLTK using ML-SPL API http://docs.splunk.com/Documentation/MLApp/4.0.0/API/Introduction. There are examples of how to bring in new algorithms into MLTK in our MLTK GitHub Repo : https://github.com/splunk/mltk-algo-contrib.
