I would say that the AI class is a good overview for the field of AI - but Machine Learning is a good in-depth discussion of the machine learning approaches, which will generally also expose you to a lot of other related AI concepts.
Thanks for that info. Now I think I will not formally enroll in the intro to AI and focus more on ML class. Since I can only truly focus on one such class at a time it would be best to enroll in something I can apply directly.
Thank you for your input here - I was considering the same question as well (AI vs. ML).
