Teach Pip with Examples

Training Data and Labels: AI for Kids

AI learns from examples, and every example needs the right label.

Data & labels, explained simply

Most of the AI you meet, from photo apps to voice assistants, learned from examples rather than from rules someone typed in. Those examples are called training data.

Each example comes with a label: the right answer. A picture of a strawberry is labelled "berry", a picture of a quartz stone is labelled "crystal". The AI studies lots of labelled examples to spot what the members of each group have in common.

Whoever collects and labels the data is the AI’s teacher. If the labels are careless or the examples are too similar to each other, the AI learns the wrong lessons. Good data is the most important ingredient in machine learning.

Example: Labelling a fruit bowl

Photo 1: red, round, bumpy → label: berry
Photo 2: clear, pointy, shiny → label: crystal
Photo 3: purple, round, smooth → label: berry
After enough labelled photos, the model can guess the label for a photo it has never seen.

Try this

Sort ten household objects into two groups and write a label on a sticky note for each. Could a friend work out your rule?
Label the same objects a second way, such as "hard" and "soft". Same data, different labels, different lesson.
Mix up one label on purpose and talk about how that could confuse a learning machine.

Questions parents and kids ask

What is training data in AI?+

Training data is the set of examples an AI learns from. For a model that recognises animals, it could be thousands of photos, each labelled with the animal it shows.

Does my child need to code to learn this?+

No. Wonderwild’s AI discoveries are hands-on activities in the browser. Children label, train and test small models themselves without writing code, so the ideas come first and coding can come later.

Prefer learning with a teacher?

Our live AI Explorers course teaches these ideas in small online classes led by a software engineer, with projects and feedback. Every live course also includes 12 months of full Wonderwild access for practice.
