Decision tree in machine learning.
A decision tree can be seen as a linear regression of the output on some indicator variables (aka dummies) and their products. In fact, each decision (input variable above/below a given threshold) can be represented by an indicator variable (1 if below, 0 if above). In the example above, the tree.
