I've written a tutorial to explain basic machine learning concepts and to show how to get started with the great Python scikit-learn library.
I hope it helps, especially if you're taking part or wanting to take part in the Repl.it AI competition!
The tutorial is published over here: https://www.codementor.io/garethdwyer/introduction-to-machine-learning-with-python-and-repl-it-rln7ywkhc
As always, keep the feedback coming!
its been fixed, i had to limit the depth of the tree, i'll start testing both trees and see if there is a difference in the results with the tree with a limited depth and the one without any limit.
Thank you very much to your time and support.
edit: i guess i'll use the result from no depth limit and then use the probability for the category with the limited depth one
