LibSVM classification results differ between Weka and Rapidminer
Using Weka and Rapidminer, I got different classification results on the same dataset with LibSVM. Even when I made the same parameters that I could change on RapidMiner in both programs, Weka gave 75% and Rapidminer 55% classification accuracy.
Also, RapidMiner SVM and Weka SMO results differ greatly too.
I would be very grateful if you could explain the reasons for these two problems.
