Study Notes
Classification Trees
- Leaves represent the predicted class or outcome in classification trees.
Decision Trees
- Decision trees are among the most popular machine learning algorithms due to their ease of interpretability and simplicity.
Regression Trees
- The target variable in regression trees can take continuous or numeric values.
Decision Tree Applications
- Decision trees can be used to visually and explicitly represent decisions in a business context, such as in decision-making processes or decision support systems.
Classification Trees
- Branches in classification trees represent the possible split or decision-making paths based on the input features or attributes.
