Building a decision tree
WebMar 28, 2024 · The basic syntax for creating a decision tree in R is: where, formula describes the predictor and response variables and data is the data set used. In this case, nativeSpeaker is the response variable and the other predictor variables are represented by, hence when we plot the model we get the following output. WebNov 15, 2024 · Before building a decision tree algorithm the first step is to answer this question. Let’s take a look at one of the ways to answer this question. To do so we will need to understand a use a few key concepts from information theory. Let’s examine this method by taking the following steps: Take a very brief look at what a Decision Tree is.

The information gained in the decision tree can be defined as the amount of information improved in the nodes before splitting them for making further decisions. To understand the information gain let’s take an example of three nodes. As we can see in these three nodes we have data of two classes and here in node 3 we have ...
