Machine learning decision tree

Apr 17, 2019 · DTs are composed of nodes, branches and leafs. Each node represents an attribute (or feature), each branch represents a rule (or decision), and each leaf represents an outcome. The depth of a Tree is defined by the number of levels, not including the root node. In this example, a DT of 2 levels.

The process of pruning involves removing the branches that make use of features with low importance. This reduces the complexity of the tree, reduces overfitting, and increases its predictive power. Out of all of the machine learning algorithms, decision trees are the most susceptible to overfitting. Pruning reduces that likelihood.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.Decision tree is a machine learning algorithm used for modeling dependent or response variable by sending the values of independent variables through logical statements represented in form of nodes and leaves.
