How does a machine learning model LEARN? // #3 of ML for Healthcare Course

In this video, we talk about different approaches machine learning models take to learning, including the ’gradient descent’ approach (which underlies much of the recent excitement) and the difference between supervised and unsupervised machine learning. We demonstrate gradient descent with several examples to build up an intuition.
