How does FaceID classify images?

Originally published on December 5, 2024 | Last modified on January 21, 2025

Overview

In this lesson, students explore facial recognition technology as a “classification task.” Each time a smartphone uses facial recognition, it asks, “Is this me or not me?” Building on lesson 1, where students learned that images are numerical representations of pixel values, this lesson helps students visualize images in multidimensional space, with dimensions equal to the number of facial variables or features in the model.

Key Terms

Machine Learning

When computers learn and get better at a task by using data instead of being programmed with explicit rules on how to do that task.

Model

A mathematical framework that can be used in AI to make predictions or decisions. Models are often trained with large amounts of data

How do I fact-check AI search results?

Studies consistently show that students are using AI chatbots and search engines like ChatGPT and Perplexity. But we know that AI makes mistakes. So, how do we teach students not to get fooled? In this lesson, we’ll introduce students to the skill of lateral reading (Wineburg & McGrew, 2017) as one approach to fact-checking the information they get from AI.

How can we mitigate bias in AI design?

This lesson introduces students to the concept of bias in AI training data and its societal implications. Using a real-world example of Google’s Gemini AI, students will explore how overrepresentation and underrepresentation in datasets affect various groups.
