WebExample 1: The Structure of Decision Tree. Let’s explain the decision tree structure with a simple example. Each decision tree has 3 key parts: a root node. leaf nodes, and. branches. No matter what type is the decision tree, it starts with a specific decision. This decision is depicted with a box – the root node. WebMar 2, 2024 · When the Decision Tree has to predict a target, an iris species, for an iris belonging to the testing set, it travels down the tree from the root node until it reaches a leaf, deciding to go to the left or the right child node by testing the feature value of the iris being tested against the parent node condition.
