Definition of decision tree in English English dictionary: A visualization of a complex decision-making situation in which the possible decisions and their likely outcomes are organized in the form of a graph that resembles a tree; A tree diagram which is used for making decisions in business or computer programming and in which the branches represent choices with associated risks, costs, results, or probabilities; A graphical representation of the decision process Sequential decisions are drawn in the form of the branches of a tree, stemming from an initial decision point and extending all the way to the final outcomes Each path through the branches of the tree represents a separate series of decisions and probabilistic events; A (typically) binary tree where each non-leaf vertex is labeled by a query, each edge is labeled by a possible answer to the query, and each leaf is labeled by an output (typically yes or no) A decision tree represents a function in the obvious way; A tree-shaped structure that represents a set of decisions Decision trees are simple knowledge representation and they classify examples to a finite number of classes, the nodes are labelled with attribute names, the edges are labelled with possible values for this attribute and the leaves labelled with different classes Objects are classified by following a path down the tree, by taking the edges, corresponding to the values of the attributes in an object These decisions generate rules for the classification of a dataset See CART and CHAID; a decision-making tool in which alternative options are portrayed graphically as branches on a tree; also referred to as a Decision Flow Diagram; a device for structured decision making that spells out the choices and possible consequences of alternative actions; A diagram used for making decisions in business or computer programming The "branches" of the tree diagram represent choices with associated risks, costs, results, and outcome probabilities By calculating outcomes (profits) for each of the branches, the best decision for the firm can be determined; A series of questions used as a tool to analyze whether training is necessary to resolve a performance problem Topic areas: Staff Development and Organizational Capacity, Accountability and Evaluation, Volunteer Management, Operations Management and Leadership; a hierarchical multi-way key, leading via a series of questions at the nodes of the tree to a decision at its leaves; Graphical representation of a logical process; A diagram consisting of nodes and branches that depicts the information for a decision problem (page 790); The decision tree, the fundamental analytic tool for decision analysis, is a way of displaying the temporal and logical sequence of a clinical decision problem Its form highlights three structural components: the alternative actions that are available to the decision maker; the probabilistic events that follow from and affect these actions, such as clinical information obtained or the clinical consequences revealed; and the outcomes for the patient that are associated with each possible scenario of actions and consequences; A method of representing knowledge which makes structures decisions in a hierarchical tree-like fashion; A tree-like way of representing a collection of hierarchical rules that lead to a class or value; The fundamental analytic tool for decision analysis, is a way of displaying the temporal and logical sequence of a clinical decision problem Its form highlights tree structural components: The alternative actions that are available to the decision maker; the probabilistic events that follow from and affect these actions, such as clinical information obtained or the clinical consequences revealed; and the outcomes for the patient that are associated with each possible scenario of actions and consequences; A graphical representation of a decision situation in which decision points (nodes) are connected together by arcs (one for each alternative on a decision) and terminate in ovals (the action which is the result of all of the decisions made on the path that leads to that oval); a graphic method of presenting various alternatives and outcomes; used to help solve complex sequential problems; A type of expert system comprised of a branching structure of questions and possible responses designed to lead an agent to an appropriate solution to a customer's problem or provide needed information Decision-tree structures resemble an organizational hierarchy Decision trees are most appropriate where the problem type is broad and shallow Decision-tree systems work well for entry-level agents, because they walk the agents through specific questions and answers However, senior agents may not want to step through each branch, since they usually know some of the questions and answers; they may feel that working through the tree process actually slows them down See branch and expert system; A graphical representation of the probable outcomes following the various decision options in a decision analysis; A graphical representation of a decision situation in which decision situation points (nodes) are connected together by arcs (one for each alternative on a decision) and terminate in ovals (the action that is the result of all of the decisions made on the path leading to that oval) (9); A schematic (pictorial) representation of the relationship between decisions, risks and outcomes It can be used as a tool to evaluate alternative strategies and make decisions The decision tree breaks down a series of events and decisions into smaller, simpler, more manageable, independent segments These segments are represented as branches of a tree The lattice concept of the tree is also used to analyse events (see event tree) and to assess risk paths that are dependent on one another; Method of representing alternative sequential decisions and the possible outcomes from these decisions; Graphical representation of decisions involved in the choice of statistical procedures; (Ticaret) A decision analysis tool that represents multiple collections of rules in the form of branches on a tree, that lead to a larger value or class
