Train a class model

Teacher demonstration. Where a demonstration helps, the teacher runs it on a school approved tool, previews it first and stays in control. The deck also includes prepared examples, so the lesson does not depend on a live demonstration working on the day. No pupil accounts. More on safety

The signature activity

Teacher-led, with no pupil accounts: the class trains an image model to sort recycling, tests it fairly, finds where it fails and improves the data.

Learning intentions

• I can plan a fair, balanced dataset.
• I can train and test a model fairly, and work out its accuracy.
• I can find where our model falls short, improve the data and explain what we did.

The slides

Teacher notes and answers sit in the speaker notes of every slide, and printable resources are at the end of the deck.
