Decision trees use various algorithms to split a dataset into homogeneous (or pure) sub-nodes.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.New in machine learning is that the decision rules are learned through an algorithm. Imagine using an algorithm to learn decision rules for predicting the value of a house ( low , medium or high ). One decision rule learned by this model could be: If a house is bigger than 100 square meters and has a garden, then its value is high.
Introduction Decision Trees are a type of Supervised Machine Learning (that is you explain what the input is and what the corresponding output is in the training data) where the data is continuously split according to a certain parameter. The tree can be explained by two entities, namely decision nodes and leaves. The leaves are the decisions or the final outcomes.
