A decision tree is a flowchart-like tree structure where an internal node represents a feature (or attribute), the branch represents a decision rule, and each leaf node represents the outcome. The topmost node in a decision tree is known as the root node. It learns to partition on the basis of the attribute value. May 2, 2019 · Furthermore, the concern with machine learning models being difficult to interpret may be further assuaged if a decision tree model is used as the initial machine learning model. Because the model is being trained to a set of rules, the decision tree is likely to outperform any other machine learning model. Decision trees are very interpretable – as long as they are short. The number of terminal nodes increases quickly with depth. The more terminal nodes and the deeper the tree, the more difficult it becomes to understand the decision rules of a tree. A depth of 1 means 2 terminal nodes. Depth of 2 means max. 4 nodes. To make a decision tree, all data has to be numerical. We have to convert the non numerical columns 'Nationality' and 'Go' into numerical values. Pandas has a map () method that takes a dictionary with information on how to convert the values. {'UK': 0, 'USA': 1, 'N': 2} Means convert the values 'UK' to 0, 'USA' to 1, and 'N' to 2.
