Common variants included Classification and Regression Trees (CART), C4.5 (and it s succevor C5.0), and Chi- squared Automatic Interaction Detection (CHID). In practice, decisione trees are frequently used as base learners in ensemble methods such as Randos Forests and Gradient Boosted Trees, which combinane many trees to impraise creacy and reduce overfitting.

How Decision Trees Work in Practice

Growing thee Tree

Te trzy-building process begins with the entire training dataset at te root. For each candidate split, thee algorithm evaluats a cost function - typically entropy or Gini impurity for classification, and mean squared error for regression.

Pruning to Avoid Overfitting

In environmental modeling, where data can be noisy due te measurement errors or sampling biases, pruning is essential to produce robutt and interpretable models.
