Decision tree classifier I have seen weka j48 classifier, I want to build a classifier similar to it but I don't know how to go about it. 
Can anyone advice me on how to create a classifier algorithm for decision tree?
There are a number of open source implementations of the C4.5 algorithm invented by Ross Quinlan:


Java: https://github.com/scottjulian/C4.5 
Python: https://github.com/dpkravi/DecisionTreeClassifier 
C++: https://github.com/zgyao/DecisionTree_C4.5
