Through hands-on projects, students gain exposure to the theory behind graph search algorithms, classification, optimization, reinforcement learning, and other topics in artificial intelligence and machine learning as they incorporate them into their own Python programs. By course's end, students emerge with experience in libraries for machine learning as well as knowledge of artificial intelligence principles that enable them to design intelligent systems of their own. *** This is CS50, Harvard University's introduction to the intellectual enterprises of computer science and the art of programming. *** HOW TO SUBSCRIBE HOW TO TAKE CS50 edX: Harvard Extension School: Harvard Summer School: OpenCourseWare: HOW TO JOIN CS50 COMMUNITIES Discord: Ed: Facebook Group: Faceboook Page: GitHub: Gitter: Instagram: LinkedIn Group: LinkedIn Page: Quora: Slack: Snapchat: Twitter: YouTube: HOW TO FOLLOW DAVID J.
