WebThe decision tree can be converted to classification IF-THEN rules by tracing the path from the root node to each leaf node in the tree. The rules extracted are R1: IF age = youth AND student = no THEN buys computer = no R2: IF age = youth AND student = yes THEN buys computer = yes R3: IF age = middle aged THEN buys computer = yes WebDecision Trees (DTs) are a non-parametric supervised learning method used for classification and regression. The goal is to create a model that predicts the value of a target variable by learning simple decision rules …
