Getting Started in AI

If you are interested in the AI field but haven't jumped in yet because you're worried about how to get started, how much it may cost to learn the fundamentals, or not even sure if you have enough time to learn something new...guess what? Stop worrying!

Machine learning, deep learning and all the other subsets of artificial intelligence (AI) have a wealth of resources. And many don't even cost a dime to learn! There are plenty of online courses that you can pay for to get certificates of completion or full-blown degrees, but if you just want to learn you can do that for free in many cases. And, at your own pace (although courses will help nudge you along with frequent reminders).

We've put together a list of some of the best online classes and sites that will do more than just have you dipping your toes in. These are free, although if you want an actual certificate you will need to pay. Some will show that you have to pay, but you can take the course in audit mode for free which gives you access to all course materials except graded items like quizzes and reviews (and certificates of completion). 

We've broken up these courses into the following sections:

  • Free Online Machine Learning and AI Courses
  • Free Online Deep Learning Courses
  • Free Online Data Science Courses
  • Free Online TinyML Courses
  • Free Online Life Sciences Courses
  • And, a little section on what to do after you grasp the fundamentals!

So browse through the list below, and good luck on your potential new career path!
