Hello, the elements of the vector are not actually probabilities, they are scores, the classification is a winner takes all approach, assigning the classification to the class with the max score.
See: http://mahout.apache.org/users/algorithms/spark-naive-bayes.html for an overview of the algorithm.

What might be the reason for this? Thanks a lot, Nantia
