Complex analysis: Summing series
This lecture is part of an online undergraduate course on complex analysis. This is a replacement for a previous video, correcting some minor typos. We show how to use the residue calculus to sum series, such as Euler's series 1/1^2 + 1/2^2+ ... Solution to exercise in rot 13: cv phorq

Gradient Descent, Step-by-Step
Gradient Descent is the workhorse behind most of Machine Learning. When you fit a machine learning method to a training dataset, you're probably using Gradient Descent. It can optimize parameters in a wide variety of settings. Since it's so fundamental to Machine Learning, I decided to mak
