Decision trees are a common type of machine learning model used for binary classification tasks. The natural structure of a binary tree lends itself well to predicting a “yes” or “no” target. It is traversed sequentially here by evaluating the truth of each logical statement until the final prediction outcome is reached.FIGURE 5.20: Learning a rule by searching a path through a decision tree. A decision tree is grown to predict the target of interest. We start at the root node, greedily and iteratively follow the path which locally produces the purest subset (e.g. highest accuracy) and add all the split values to the rule condition.
