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).When applied on a decision tree, the splitter algorithm is applied to each node and each feature. Note that each node receives ~1/2 of its parent examples. Therefore, according to the master theorem, the time complexity of training a decision tree with this splitter is:Decision Trees are supervised machine learning algorithms used for both regression and classification problems.

A decision tree begins with the target variable. This is usually called the parent node. The Decision Tree then makes a sequence of splits based in hierarchical order of impact on this target variable. From the analysis perspective the first node is the root node, which is the first variable that splits the target variable.
