Sorry, but I absolutely do not recommend it. It is too much theory for a beginner. Instead, I'd recommend "Hands on Machine Learning with Scikit & Keras". Decent theory + lots of practice. https://www.amazon.com/Hands-Machine-Learning-Scikit-Learn-T...

Can you elaborate what you would do with machine learning techniques? In what capacity? I'd love to understand what problems you have.

Generally speaking, a great book to start with is this - https://www.amazon.com/Hands-Machine-Learning-Scikit-Learn-T...

OK, since it is for a teenager I would assume just basic computer competency (how to install programs and stuff like that) but nothing else, so apologies if some of these things are pretty obvious/basic..

I would (assuming zilch knowledge and tools).

- Install Python. https://www.python.org/downloads/

- Install VSC https://code.visualstudio.com/

- Install the python extension for VSC https://marketplace.visualstudio.com/items?itemName=ms-pytho...

- learn a little bit of python. This is a good resource, but there are several more, even the official documentation is very good

- After some familiarity with python one option is this free book:

http://neuralnetworksanddeeplearning.com/

- Another, good (but paid) option is this book: https://www.amazon.com/Hands-Machine-Learning-Scikit-Learn-T...

Or a third option is indeed Andrew Ng's course.

Now, for any of those 3 options a little (or a lot) of guidance and patience will be needed so hopefully you or some friend/peer can help with that. Good luck!
