What is the purpose of the What-If Tool?

• A. To test performance in hypothetical situations and visualize behavior
• B. To automate model hyperparameter tuning
• C. To monitor production latency
• D. To manage user access control

Answer: (A)

Testing model behavior under hypothetical input changes and visualizing how predictions respond is what the What-If Tool is designed to do. It lets you modify input features, run the model to see resulting predictions in real time, and explore how small or large changes affect outcomes. This is especially useful for examining edge cases, counterfactual scenarios, and fairness across different subgroups, since you can compare predictions and metrics across subsets of data and visualize decision boundaries for classifiers.

The other options don’t fit this tool’s purpose: automating hyperparameter tuning is a separate process using tuning methods, monitoring production latency is about observability, and managing user access control concerns security and identity management.
