oriental_express Posted November 24, 2008 Share Posted November 24, 2008 hi there everyone. I need to create a question based decision tree (select the answers), depending on the answer the script will load different questions until the solution is found. I understand the basics of what ID3 des, but what I've been told by my lecturer data can be loaded on to a txt file and somehow the php script can be created based on the decision tree. My questions is how can I do so ? I've looked all over google for 'php decision tree ID3 algorithm' but nothing has come up. I can create the knowledge like the one below, but how do i feed this to a script once this has been written in txt file ? I would be grateful for any pointers.
