Using ClassifierDemo class provided below https://bitbucket.org/jaganadhg/blog/src/tip/bck9/java/src/org/bc/kl/ClassifierDemo.java
I tested the 20news test data with the trained model. It worked fine. However, when I ran the same class (ClassifierDemo) against my own test dataset with my own trained model, I received the following messages. It basically is returning NaN per potential class. And the final label it is assigning the test dataset to is wrong and is always the same label: "Health", which is the default category, I think. Why is it doing this? I am pretty sure I trained it and generated the model correctly.
