Reading about AI is easier when you have a small exercise to try. These three exercises use synthetic or public sample material and focus on observing behavior—not claiming that a model is accurate or ready for important decisions. Check current account requirements and terms on each provider’s site before using a service.
Exercise 1: Sort short feedback into themes
Create a small set of fictional feedback lines such as “setup was clear” and “the export button was hard to find.” Ask a text model to group the lines into themes and quote the line supporting each theme. Then compare every grouping with your own labels. Add an ambiguous line and see whether the tool admits uncertainty. Do not use real customer feedback unless you have permission and an approved data-handling process.
Exercise 2: Make a simple image classifier
Use Google Teachable Machine to explore a small image-classification project with objects you can photograph or sample images you are allowed to use. Keep the classes visually distinct at first. Test with a new image that was not used during training, change the lighting or background, and note where predictions fail. This classroom-style experiment illustrates why sample selection matters; it is not evidence of production accuracy.
Exercise 3: Inspect a beginner machine-learning lesson
Choose one exercise from Google’s Machine Learning Crash Course. Before reading the solution, write down what you expect the model or calculation to do. Complete the exercise, compare your reasoning with the explanation, and note which assumption you misunderstood. Check the lesson’s current prerequisites and exercise environment before starting.
Keep a one-page learning record
For each exercise, record the goal, the sample input, the expected output, the observed output, one failure case, and what the exercise cannot tell you. This helps separate a demonstration from evidence. A small toy dataset cannot establish real-world accuracy, fairness, security, or suitability for a high-impact task.
Safety and privacy
- Use fictional or otherwise permitted sample data.
- Do not upload personal, confidential, regulated, or copyrighted material without authorization.
- Verify factual outputs against original sources.
- Keep a person responsible for consequential choices.
Add an expected result and a failure check to each exercise
Before you run an exercise, write the result you expect and a case that should make the tool uncertain. This turns a demonstration into a small learning activity without pretending it measures real-world performance.
- Feedback themes: create fictional lines with two obvious themes and one ambiguous comment. Ask for each proposed theme to include the exact supporting line. Check whether it invents a theme or ignores the ambiguous item.
- Image classification: keep training examples separate from the new image used for checking. Change a harmless background or lighting condition and note whether the model follows the object or the incidental setting. Do not treat a small classroom set as an accuracy estimate.
- Course exercise: before reading an explanation, write down your prediction. Afterward, record which assumption changed and find the lesson’s explanation for the difference.
Use a compact log with the exercise goal, data source, expected result, observed output, failure case, and privacy note. If a tool asks you to upload personal or copyrighted material, stop and choose a permitted sample instead. This page offers standalone practice exercises; for a connected project progression with a reusable README, use the project-based learning path.
