CS229LectureNotes - Stanford University

CS229 Lecture Notes Andrew Ng (updates by Tengyu Ma). Supervised learning Let's start by talking about a few examples of supervised learning problems. Suppose we have a dataset giving the living areas and prices of 47 houses from Portland, Oregon: Living area (feet2 ) Price (1000$s). 2104 400. 1600 330. 2400 369. 1416 232. 3000 540.. We can plot this data: housing prices 1000. 900. 800. 700. 600. price (in $1000). 500. 400. 300. 200. 100. 0. 500 1000 1500 2000 2500 3000 3500 4000 4500 5000. square feet 1. 2. Given data like this, how can we learn to predict the prices of other houses in Portland, as a function of the size of their living areas?
