Introduction to Deep Learning

6.S191 is MIT's introductory course on deep learning, taught during the January Independent Activities Period by Alexander Amini and Ava Soleimany; OpenCourseWare publishes the lecture videos, and the listing currently reflects the January 2026 edition. The course covers deep learning methods and their applications to computer vision, natural language processing, biology and other areas. Students are meant to leave with foundational knowledge of deep learning algorithms and hands-on experience building neural networks in TensorFlow, and the on-campus class ends with a project proposal competition judged by staff and industry sponsors.

Stated prerequisites are calculus at the level of taking derivatives and linear algebra at the level of matrix multiplication; the instructors say they will try to explain everything else along the way, and that Python experience is helpful but not required. Compared with MIT's semester-long OpenCourseWare offerings, this is a short, intensive series: the OCW page is essentially a gateway to the lecture videos rather than a full set of notes, problem sets and exams, so pair it with a linear algebra or machine learning course if you want practice material. The videos are free, no account is needed, the content is shared under a Creative Commons licence, and no certificate is offered.
