Decision Trees and space partitioning

Decision trees are one of the most intuitive and at the same time powerful machine learning algorithms. They are loved for their clarity, for being close to the human “if–then” logic, and for the fact that the result can be explained not only to an engineer, but also to the business, a manager, or a client. Unlike many other models, a decision tree does not look like a black box — it can literally be drawn on paper.
