What is a Decision Tree?

A decision tree is a graphical depiction of a decision-making process that displays many options, consequences, and possible courses to take. It graphically illustrates the many options, their implications, and the probability associated with each option. Decision trees are often used to aid logical thinking and improve decision-making in industries such as business, finance, healthcare, and project management.

Why Do We Use Decision Trees?

Decision trees have several benefits, making them popular decision-making tools. For starters, they give a visual depiction of difficult decisions, making them easier to grasp. Decision trees simplify even the most complex circumstances by breaking down the decision-making process into distinct branches and nodes. They assist decision-makers in identifying prospective options, assessing probable outcomes, and weighing the risks and advantages.

Furthermore, decision trees aid in the organization and structuring of information, allowing for a methodical approach to issue-solving. They encourage logical thinking by presenting options and their implications in an organized and hierarchical format. Decision trees also improve team communication and collaboration by providing a common visual depiction of the decision-making process.

Decision trees also encourage consistency and openness in decision-making processes. They explain why each choice was made, making it easy to analyze and assess the rationale and assumptions involved. Transparency is especially vital when there are several stakeholders engaged since it increases trust and confidence in the decision-making process.

Parts of a Decision Tree:

A decision tree consists of several components, including decision nodes, chance nodes, branches, and end nodes.

1. Root Node:

The root node is the decision tree’s beginning point. The root node indicates the first choice or question to address. It extends branches to numerous decision or chance nodes, symbolizing the many options or courses that individuals can pursue.

2. Decision Nodes:

In a decision tree diagram, squares represent decision nodes. Decision nodes signify points in the decision tree where the decision-maker must make choices or decisions. Decision nodes represent the numerous options or alternatives available to the decision-maker.

3. Chance Nodes:

In a decision tree, chance nodes are represented by circles. They represent a moment at which unclear outcomes or occurrences occur. Probabilities, which describe the likelihood of each result, are related to chance nodes.

4. Branches:

Branches in a decision tree are the lines or arrows that connect decision nodes, chance nodes, and end nodes. They indicate the decision-maker’s possible pathways or options. Each branch connects nodes and depicts the decision-making process flow.

5. End Nodes:

End nodes, also known as terminal nodes, are represented by rectangles in a decision tree. They signify the outcomes or decisions reached at the end of the decision-making process. End nodes represent the result of a specific path or choice in the decision tree.

6. Subtrees:

Subtrees are smaller decision trees within the main decision tree. They represent a subset of decisions or outcomes within a larger decision-making process. Subtrees break down complex decisions into more manageable components, making the overall decision tree easier to understand and navigate.

7. Splitting Criterion:

The splitting criterion is a rule or condition used at each decision node to determine the path to take. It helps in dividing the data or decision space based on certain attributes or criteria. The splitting criterion is typically based on factors such as information gain, Gini index, or entropy, depending on the specific decision tree algorithm used.

8. Leaf Nodes:

Leaf nodes, also known as terminal nodes or result nodes, are the final nodes in a decision tree. They represent the ultimate outcomes or decisions reached based on the choices made along the branches. Leaf nodes provide the final answers or predictions related to the decision-making process.

9. Parent and Child Nodes:

In a decision tree, nodes are interconnected through parent-child relationships. A parent node is a node that branches out to one or more child nodes. The child nodes, in turn, can further branch out to their child nodes. This hierarchical structure helps in organizing and representing the decision-making process.

Symbols and Meaning:

Symbols play an important role in decision trees as they help convey specific meanings. Here are the commonly used symbols in decision tree templates and their meanings:

  • Decision Node Symbol (Square):
    The decision node symbol represents a point in the decision tree where the decision-maker needs to make a decision. It typically denotes a choice or alternative that the decision-maker must select.
  • Chance Node Symbol (Circle):
    The chance node symbol is represented by a circle. It signifies a point in the decision tree where uncertain outcomes or events occur. Chance nodes are associated with probabilities that represent the likelihood of each outcome.
  • End Node Symbol (Rectangle):
    The end node symbol is represented by a rectangle. It signifies the outcomes or decisions reached at the end of the decision-making process. End nodes represent the result of a specific path or choice in the decision tree.
  • Branch Symbol (Line/Arrow):
    Lines or arrows link decision nodes, chance nodes, and end nodes to form branches. They depict the flow of decision-making, demonstrating the many courses that might be pursued based on decisions made.

It is critical to use these symbols consistently and effectively to accurately portray the decision-making process. They add to the decision tree’s visual clarity and understanding, making it simpler to perceive and express decision-making reasoning to others.

When making a decision tree, make sure that each symbol is adequately labeled with informative language. This labeling clarifies the meaning of each symbol and improves overall comprehension of the decision tree. We recommend you read our previous article on “Anomaly Detection“.

How to Draw a Decision Tree?

Drawing a decision tree involves a step-by-step process. Here’s a guide on how to draw a decision tree:

  • Identify the Main Decision:
    Determine the central decision or question that needs to be addressed. This will be the starting point of your decision tree.
  • Determine the Alternatives:
    Identify the different choices or alternatives that are available about the main decision. These will branch out from the main decision node.
  • Consider Potential Outcomes:
    Think about the potential outcomes or consequences associated with each alternative. These outcomes will be represented as chance nodes in the decision tree.
  • Assign Probabilities:
    Assign probabilities to each potential outcome. These probabilities should indicate the possibility or chance that each of the outcomes will occur.
  • Connect the Nodes:
    Start by drawing the main decision node, representing the initial choice to be made. From the decision node, draw branches representing the different alternatives or paths that can be chosen. Label each branch with the respective alternative.
  • Add Chance Nodes:
    For each alternative, draw a chance node to represent the potential outcomes. Connect the chance nodes to the corresponding alternative branches using additional branches.
  • Extend the Decision Tree:
    Repeat the process of adding decision nodes, chance nodes, and branches as needed, depending on the complexity of the decision-making process. Continue until you have represented all the decisions, alternatives, and outcomes in the decision tree.
  • Label Nodes and Branches:
    Clearly label each node and branch with descriptive text to ensure clarity and understanding. This will help communicate the decision-making process effectively.
  • Review and Refine:
    Take a step back and review the decision tree for accuracy, logical flow, and completeness.
  • Customize and Enhance:
    Customize the appearance of the decision tree by adding colors, formatting, and design elements. This can help improve the visual appeal and comprehension of the decision tree.
