Decision tree grafting is a machine learning technique that adds tests and
nodes to existing decision trees, resulting in bagging-like variance
reduction while providing a single directly interpretable decision tree.
Experiments demonstrate that decision tree grafting consistently reduces
prediction error over a wide range of learning tasks. This talk presents
the motivations for decision tree grafting, two algorithms, an analysis of
the relationship between pruning and grafting, and experimental results.
