# Machine Learning Basics

A basic explanation of machine learning: a computer studies many examples, finds patterns and makes predictions about new things. Includes hands-on practice with Teachable Machine or a similar tool.

Subject: Computing · Area: Artificial Intelligence · Ages 7 to 9

## Ready when they can

- Describe the three steps of machine learning in simple terms (give examples, find patterns, make predictions)
- Train a simple model using a tool like Teachable Machine and describe what happened
- Explain how relevant, varied examples can help a model and why its guesses still need testing

## Lesson: Teaching a computer to notice things

You have sorted things by a rule. Machine learning lets a computer learn patterns from examples. People write the learning software. For our picture sorter, first give labeled examples, then train it to find clues that separate the groups. Next, try a new picture and check its guess. A guess is called a prediction.

*(drawing: Training and checking are different jobs. The new picture is not one used for training.)*

**Example.** Nora uses Teachable Machine to sort sneakers and rain boots. She supplies labeled photos, selects Train, then checks new photos. A guess matching the known label is correct; a different label is a mistake. The model might use shape or background clues. To compare results, subtract the smaller number of correct guesses from the larger: 8 minus 6 is 2 more.

*(drawing: In this made-up test, A got 6 right and B got 8 right out of 10. Results depend on the training examples and the test pictures.)*

Useful examples show different shoes, angles, light and backgrounds. Repeating one photo adds little variety. If boot photos are rainy and sneaker photos are dry, a model may learn rain as a clue. Show both kinds in different weather. More relevant, varied examples can help, but test new pictures to find out.

**Recap.** Give examples, train the model, then check its guesses on new examples. Relevant variety can help it learn useful patterns.
