Introduction to algorithms

In this section, we will look at the decision tree algorithm. We will go through an example to understand the algorithm. Once we get some clarity on the algorithm, we will try to understand the random forest algorithm with an example.

Decision tree 

To understand the random forest model, we must first learn about the decision tree, the basic building block of a random forest. We all use decision trees in our daily lives, even if you don't know it by that name. You will be able to relate to the concepts of a decision tree once we start going through the example.

Imagine you approach a bank for a loan. The bank will scan you for a series of eligibility criteria before they approve the...
