Update classifier in weka with one instance

Question

I ve trained a Smo classifier in weka and I am interested in update my classifier. I ve found UpdateableClassifier Interface. However, I can't found, how this interface works. How is it then, possible to update my trained classifier with only one instance?

Answer 1

Only those classifiers implementing the UpdateableClassifier allow that option. Unfortunately, SMO does not implement this interface, so you have to re-train your classifier on the dataset plus the new instance. Check the page for the interface to see which classifiers currently implement it.
