I will also be tuning hyperparameters and pruning a decision tree ...Machine Learning - Decision Trees Algorithm. The Decision Tree algorithm is a hierarchical tree-based algorithm that is used to classify or predict outcomes based on a set of rules. It works by splitting the data into subsets based on the values of the input features. The algorithm recursively splits the data until it reaches a point where the ...Learning decision trees • Goal: Build a decision tree to classify examples as positive or negative instances of a concept using supervised learning from a training set • A decision tree is a tree where – each non-leaf node has associated with it an attribute (feature) –each leaf node has associated with it a classification (+ or -)
