Decision Trees explained by Pompeo Pontone

Currently working in the fields of Quantitative Finance, Derivatives Trading, FinTech, Data Science, and Private Equity, Pompeo Pontone explains why Decision Trees are so important within Data Science: “Decision trees (DTs) are among the most versatile class of machine learning algorithm”, he writes, “they’re particularly useful as the basic classifier and random forests which are among the most powerful class of machine learning algorithm”. As pointed out by the Investment Consultant and Specialist, indeed, a decision tree is a non-parametric supervised learning algorithm used for classification and regression problems. His article underlines that the goal of Decision Trees “is to create a model that predicts the value of a target variable by learning simple decision rules inferred from the data features”, expert says, adding that such methods are “capable of handling both classification and regression tasks and they’re able to deal with complex nonlinear datasets”Pompeo Pontone continues his article by explaining another useful feature of Decision Trees, which are also called “white-box models”, as they are easy to interpret: “This is because they’re based on a hierarchy of simple classification rules which are easily visualized”, he writes, and “this is an opposition to black-box models like deep neural networks. In black-box models, decisions are made in a process which is far more opaque”. The Investor and Investment Specialist concludes his article by adding that “with Decision Trees, we can easily traverse the tree by eye and see the criteria for how the decisions are made”.
