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 make a step-by-step video that shows you exactly how it works. • NOTE: This video assumes you are already familiar with Least Squares and Linear Regression. If not, here's the link to the Quest: • The Main Ideas of Fitting a Line to D... • For a complete index of all the StatQuest videos, check out: • https://statquest.org/video-index/ • Sources: • There are a ton of websites that describe the math behind Gradient Descent.
