1. I have naive bayes implementation on the dataset with 16 attributes, with label which is of type nominal (String)
2. With Naive Bayes I could get the desiered results, when I try to implement adaboost and having Naive Bayes as the Learning Process and providing Input values from the CSV file to the apply model I'm getting a SEVERE: java.lang.NullPointerException in the Set Role Operator. Can you please advice.
3. My goal is apply the CSV sample data on to the trained model outcome from Adaboost algorithm.
