In this session, you will be able to watch videos, do quizzes and complete programming assignments. CART Classification and Regression Trees (CART), commonly known as decision trees, can be represented as binary trees. CS229 Lecture notes Andrew Ng Supervised learning Let’s start by talking about a few examples of supervised learning problems. To establish notation for future use, we'll use x(i) to denote the "input" variables (living area in this example), also called input features, and y(i) to denote the "output" or target. Random forest It is a tree-based technique that uses a high number of decision trees built out of randomly selected sets of features. We strongly recommend you review this baseline problem set from the Fall 2018 graduate course upon which much of this course is based. Cs124 Stanford Github txt) or read online for free.
