Hey,
We are using the classification template 
<https://github.com/apache/incubator-predictionio-template-attribute-based-classifier>
 of PredictionIO (algorithm modified to random forest instead of Naive Bayes'). 
We wanted to ask how is the random forest classifying a test input: By the 
number of votes each tree give or the mean of the probability of each label in 
each tree)? Also, can we extract the mean probability of each class for a 
particular input so that we can get an idea of how is the strength of the 
prediction? And does this probability value reflect the absolute tendency of 
the input to belong to the said class?
