Documenting and evaluating a machine learning model

This unit is designed to develop pupils programming skills in a new engaging context: physical computing, using the BBC micro:bit. They will get acquainted with the host of components built into the micro:bit, and write simple programs that use these components to interact with the physical world.

Machine learning using the micro:bit

Rule-based systems are more advanced than data-driven systems.

Data-driven systems rely on fixed, predefined rules.

Data-driven systems make predictions based on patterns in data.

Data-driven systems do not use any data for decision-making.

What is the key difference between a rule-based system and a data-driven system?

AI systems make {{ }} based on patterns found in large amounts of data.

A traffic light system is an example of a {{ }} system because it follows pre-programmed instructions.

A handwriting recognition system that improves over time is an example of a {{ }} system.

They compare patterns in data and adapt based on feedback.

They memorise data without making comparisons.

They rely on human input for every decision.

a TV recommendation system that suggests shows based on viewing history

a handwriting recognition system that improves over time

a self-learning thermostat that adjusts temperature based on past preferences

a chatbot that always responds "Hi!" when you say "Hello"
