nice! upvote this one. i suggest you start with Python, and install Anaconda for it. You can view my post if you don't know how. Then you learn scikit learn and dive into decision tree of it. Search decision tree on YouTube, and you'll find tons of tutorials. I learned it from a lot of people, and I like Sentdex's one. If you want a simplified version, I'm planning on writing one, but I'm still wrecking my brain about it
