Which ONE of the below types of testing is NOT a type of experience based testing applied to an AI based system?

• A.Usability testing of the format of the output predictions
• B.Using an industry checklist to assess the steps used to prepare an ML system
• C.Exploring training data to understand its variety, patterns, structure and shape - then using that to inform testing

Before deployment of an AI-based system, a developer is expected to demonstrate in a test environment how decisions are made. Which of the following characteristics does decision making fall under?

• A.Explainability
• B.Autonomy
• C.Self-learning
• D.Non-determinism

An e-commerce developer built an application for automatic classification of online products in order to allow customers to select products faster. The goal is to provide more relevant products to the user based on prior purchases.
Which of the following factors is necessary for a supervised machine learning algorithm to be successful?

• A.Minimizing the amount of time spent training the algorithm
• B.Labeling the data correctly
• C.Selecting the correct data pipeline for the ML training
• D.Grouping similar products together before feeding them into the algorithm

A test engineer is planning testing for a wearable medical device using AI. The medical device will detect possible heart issues in patients and dispatch emergency services automatically. It is not expected that many patients will have heart issues, and this is reflected in the available data. In this case, it is decided it is more important that emergency services are not sent un-necessarily, than it is to detect actual heart problems.
Which ONE of the following metrics should the test engineer choose to ensure that the emergency services are sent only when needed?

• A.R-Squared
• B.Accuracy
• C.Precision
• D.MSE
