Hands-On Data Structures and Algorithms with JavaScript

Coding the ID3 algorithm

First, we would need to have an application; let's go ahead and create an Angular application as shown previously.

From the previous example, we have seen that the first thing we will need is to list out our training data, which will be fed into our algorithm. In this case, we will need to first identify the different attributes that are affecting our target attribute (approved).
