Scatterplots to Decision Surface – Intro to Machine Learning


What our machine learning algorithms do is, they define what’s called a decision surface. They typically lies somewhere between the two different classes, like this one over here. And on one side they will predict red cross for every possible data point. Whereas on the other, they predict the opposite concept. So with the decision surface over here, it’s now easy to say what the label would be for data point over here. And again, I give you two choices, red cross or blue circle
