J48 decision tree

Question

I've been searching the web on how to generate J48 decision trees but so far after almost a couple days I haven't found any result about how to generate a J48 decision without Weka, I mean manually by hand. The reason why I wanna do this is because I need to evaluate my data in an assignment.

I would appreciate any information about the j48 algorithm.

Answer 1

The J48 classifier implements the C4.5 algorithm. You should be able to use either a description of that or, if you need to be exactly like what Weka does, you can step through the code itself.

Answer 2

you can use weka as well for developing a simple code, what you have to do, download the jar file of weka, and study the API of weka which is provided by weka as well. and develop your own program to use the algorithm and implement it on your data
