Sample Quiz Quiz

Explore foundational concepts and terminology in artificial intelligence applications and machine learning. This quiz covers essential areas including supervised learning, neural networks, and common use cases in AI.

1. Supervised Learning Example

   Which scenario best illustrates supervised learning in AI?

   1. A clock that tells the time
   2. A photo app that labels images based on previous examples
   3. A sensor that measures temperature
   4. A chatbot that responds randomly

   Explanation: Supervised learning involves training a model using labeled examples, such as a photo app learning from labeled images to classify new ones. The chatbot responding randomly does not use learning from data. Measuring temperature and telling time are simple reporting functions, not learning processes.

2. What Does a Neural Network Model Mimic?

   In AI machine learning, a neural network loosely mimics which of the following?

   1. The solar system orbit paths
   2. A computer's hard drive storage
   3. A filing cabinet's structure
   4. The human brain's network of neurons

   Explanation: Neural networks are inspired by the structure and function of the human brain's neurons. Hard drives store data but don't process it like neural networks. The solar system and filing cabinets are unrelated to the neural design concept.

3. Typical Use for AI in Healthcare

   Which is a common application of AI in healthcare today?

   1. Predicting patient diagnoses from medical images
   2. Encrypting network traffic
   3. Designing athletic shoes
   4. Powering social media feeds

   Explanation: AIs are used in healthcare to analyze images and assist with diagnoses. Encrypting network traffic relates to cybersecurity, social media feeds are media-related, and athletic shoe design is a manufacturing example, not a typical healthcare use.

4. Unsupervised Learning Use Case

   Which task is most suitable for unsupervised learning in machine learning?

   1. Translating languages
   2. Calculating simple arithmetic
   3. Predicting tomorrow's weather
   4. Grouping customers by purchasing patterns

   Explanation: Unsupervised learning finds patterns or groups without labeled outcomes, such as customer segmentation. Weather prediction and translation are supervised tasks, while arithmetic does not require learning.

5. AI in Everyday Technology

   Which device commonly uses AI for speech recognition?

   1. Mechanical wristwatch
   2. Analog kitchen scale
   3. A manual typewriter
   4. A smartphone virtual assistant

   Explanation: Smartphone virtual assistants use AI to recognize and respond to speech. Manual typewriters, kitchen scales, and wristwatches do not include AI or speech recognition capabilities.
