context_page_description: A decision tree is a decision support tool that uses a tree-like model of decisions and their possible consequences, including chance event outcomes, resource costs, and utility. It is one way to display an algorithm that only contains conditional control statements.
  Decision trees are commonly used in operations research, specifically in decision analysis, to help identify a strategy most likely to reach a goal, but are also a popular tool in machine learning.
context_section_description: Much of the information in a decision tree can be represented more compactly as an influence diagram, focusing attention on the issues and relationships between events.
caption: The rectangle on the left represents a decision, the ovals represent actions, and the diamond represents results.
