Introduction to Neural Networks

Learn why neural networks are such flexible tools for learning.

Artificial neural networks learn by detecting patterns in huge amounts of information. Much like your own brain, artificial neural nets are flexible, data-processing machines that make predictions and decisions. In fact, the best ones outperform humans at tasks like chess and cancer diagnoses.

In this course, you'll dissect the internal machinery of artificial neural nets through hands-on experimentation, not hairy mathematics. You'll develop intuition about the kinds of problems they are suited to solve, and by the end you’ll be ready to dive into the algorithms, or build one for yourself.



Concepts and

  1. 1


    When traditional AI hit a dead end, artificial neural nets jumped in.

    1. Can Computers Learn?

      Do you have to be living to be learning?

    2. The Computer Vision Problem

      What's so hard about artificial intelligence? Try seeing in pixels.

    3. The Folly of Computer Programming

      Why do we need neural networks? Some things just can't be programmed.

    4. Neural Networks

      Teaching machines to teach themselves.
