Your New Data Science and Machine Learning Instructor

Interested in learning artificial intelligence (AI), deep learning, machine learning, and data science? You've come to the right place.

What can I do for you?

Courses in machine learning and data science that will take you from beginner to advanced more quickly than the typical college program (no more formulas without any explanation!) or the typical online course (no more spending 60 hours just to learn 3 lines of library code!).

If you're completely new and you don't know which course to start with, I've created custom learning paths to fit your goals, whatever they may be.

Free tutorials and videos in deep learning and AI.
