MaxPriorProbability 

Returns the index of the class, which has the highest count of examples and thus the highest prior probability, with ClassIndex.  

 

PostPrune 

Pruning disables some attributes, to improve classification accuracy.  

 

PrePrune 

Pruning disables some attributes, to improve classificaiton accuracy.  

 

Prune 

Performs pre-pruning and post-pruning and enables only those attributes giving best classification accuracy towards the test dataset.
