CS50 AI - HarvardX
CS50 AI from HarvardX is an online course that teaches core concepts used in artificial intelligence. It is divided into multiple chapters, and students complete projects to solve specific problems.
If you are curious about this course, you can look at the course page.
I took this course during my second year of my BSc to get an overview of the foundations of artificial intelligence. I found it interesting and worked on projects I probably wouldn’t have tried otherwise (for example, a knowledge-based program).
Today, I don’t think the projects and content of this course are particularly relevant to describe in detail, but for people who are interested in AI, it can be a good baseline alongside other resources (especially to learn the necessary mathematics).
Also, the edX verified certificate is not free. If you complete the course without paying, you can still get a certificate of completion, but it is not a verified credential. edX may also offer discounted pricing for students who cannot pay the full price.
