DECISION TREES Meaning and
Definition
-
Decision trees are predictive models used in machine learning and data mining to provide a systematic approach for decision-making in an organized, tree-like structure. This method of analysis is based on a hierarchy of decisions and their possible outcomes, represented by nodes and branches. It is an efficient algorithm that provides a visual representation of decision-making processes and enables data-driven classification and regression tasks.
In decision trees, the root node represents the initial decision or starting point, and subsequent nodes represent different conditions or criteria that lead to further decisions or outcomes. Each node splits into branches based on specific features or attributes of the data, and each branch represents the potential outcome of that decision. The process continues until a final outcome or result is reached, usually represented by leaf nodes in the tree.
Decision trees are frequently used in various fields including finance, healthcare, and marketing, as they provide an easily interpretable and understandable model for making predictions and analyzing complex data. They are known for their ability to handle both categorical and numerical data and can effectively solve problems involving classification, regression, and even outlier detection.
By following the branches of a decision tree, one can determine an optimal path to take for a given situation, making it a valuable tool for decision-making and problem-solving in diverse domains. Decision trees also offer the advantage of being computationally efficient and robust, able to handle large datasets with relatively low computational cost.

Etymology of DECISION TREES
The term "decision trees" originates from the combination of two words: "decision" and "trees".
The word "decision" comes from the Latin word "decisio", which means "a cutting off" or "a determination". It derives from the verb "decidere", composed of "de-" (meaning off) and "caedere" (meaning to cut). In English, "decision" refers to the act or process of making a choice or reaching a conclusion.
The word "trees" is derived from the Old English word "trēow". It has Germanic origins and is akin to the Old Norse word "tré" and the Dutch word "tree". "Trees" refers to large perennial plants, typically with a single trunk and branches.
