If you are looking to get a deep understanding of the principles that drive supervised learning, presented in an easy-to-understand manner, then this is the right course for you. The content is very logically structured, and examples are meaningfully selected to allow a good understanding of why we do what we do. The labs that each video is centered around are user-friendly and excellent for learning, reinforcing concepts and allowing the learner to try things out for themselves.
