Adding support for large, multi-dimensional arrays and matrices, along with a large collection of high-level mathematical functions to operate on these arrays.
Tons of math formulas, and if you don't have a decent background in machine learning, you might get lost, however there are still some concepts in the video which are very useful in pracital usage, especially lecture 8 and 13.
They deliver not only academic-oriented concepts but also industry-oriented concepts. Also, the following point might be subjective, but this tutorial boosts my interests in machine learning the most out of three.
