Hello Freelancers, We are in need of an expert in data mining primarily. We have a simple decision tree structure that gives us certain result depending on multiple inputs. We have multiple clients with different decision trees. We though, rather then hardcoding this with multiple if else statements, if we can somehow store that decision tree inside database. Or File. Simple json javascript object will do the job maybe. We were able to find something called PMML, but noone with skills to work with it. We also need nodejs program that can read that structure and give us output using that structure. Please outline basic flow in your bid. Looking forward to hearing your ideas. Thanks, Kristijan

Hi, I teach data structures courses in a university, I am sure I can help you. I think the best here would be using a json because it can store data recursively which is great for storing a tree. On each node there should be stored the name of the decision variable as well as a comparison operator and a value to make the decision... or maybe a complex expression for making decisions. On the other hand in order to evaluate this json it is necesary to traverse the tree checking recursively the value of the expression until a leaf of the tree is reached.
