WebFeb 20, 2024 · The Decision Tree works by trying to split the data using condition statements (e.g. A < 1 ), but how does it choose which condition statement is best? Well, it does this by measuring the " purity " of the split (conditional statements split the data in two, so we call it a "split"). WebA tree exhibiting not more than two child nodes is a binary tree. The origin node is referred to as a node and the terminal nodes are the trees. To create a decision tree, you need to follow certain steps: ... Therefore, if the variable splits an individual by itself, Decision Trees may have a faulty start. Therefore, trees require good ...
