Study Notes
Decision Tree Purpose
- Decision trees help visualize and understand complex decisions by breaking them down into simpler steps.
- They represent a series of choices and their possible outcomes, helping to identify the best path based on available information
Restaurant Decision Tree Variables
- Patrons: Represents the number of people currently waiting for a table at the restaurant.
- Reservation: Indicates whether a customer has a pre-booked table at the restaurant.
- Type: Represents the type of cuisine offered by the restaurant, for example, Italian, Mexican, or Asian.
- WaitEstimate: Indicates the estimated waiting time for a table at the restaurant.
Factors Influencing Wait Decision
- Patrons: The number of people waiting can influence the decision to wait or find another restaurant.
- Reservation: Having a reservation eliminates the wait time, making it a significant variable for decision making.
- Type: The type of cuisine desired can influence the decision, as customers might be willing to wait longer for a specific type of food.
- WaitEstimate: The estimated waiting time is a crucial factor, as customers typically consider their time constraint while making the decision.
Decision Tree for Restaurant Decisions
- The decision tree uses the above variables to guide customers through the process of deciding whether to wait for a table based on the current situation at the restaurant.
- This helps predict the potential outcomes of waiting, enabling customers to make informed decisions.
Variable Definitions
