[LAB] Building a model in Scratch3
If you take a few images with a webcam, label them, and learn them, you can classify similar new images based on the learning results. The captured images are not sent to the server, and all learning and classification are performed in the browser. (However, a network connection is required to load the application at startup and to download the learning model.)

You’ve started to train a computer to recognise pictures. But instead of trying to write rules to be able to do this (programming), you are doing it by collecting examples. These examples are being used to train a machine learning “model”.
This is called “supervised learning” because you are supervising the computer’s training. The computer will learn from patterns in the example photos you’ve chosen, such as the shapes and the use of colour. These patterns will then be used by the model to recognise new images.
Your teacher will use the examples you have collected to train the model to recognise cars and cups.
How accurately did your model sort the images?
If it made any mistakes have a look at the images it got wrong – is there anything similar about them? Do they have the same background or have they got the same colour on them.
Add some more images to your test data and rerun you model – have you improved the accuracy?
