Gathering data for a model

Computing

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

a category assigned to multiple data points

What is a sample in the context of gathering data for a model?

{{ }} is measured in three directions: x (side-to-side), y (forward-backward), and z (up-down).

because computers cannot understand numerical data

so the model can predict whether a movement is good or bad based on patterns

Why do we label movement data with 'good' and 'bad'?

A {{ }} is a way of representing something in the real world using data patterns.

a system that represents real-world data patterns

a method where decisions are based on patterns in data

When creating a movement model, motion values for x, y and z are plotted against ...

a chatbot that always gives the same response

a smart thermostat that adjusts over time

The phrase ‘I know!’ appears in the Quick Draw system when enough {{ }} is provided for a high-confidence prediction.

It makes decisions based on pre-defined rules.

It improves by adapting how it finds patterns in data.

It does not require large amounts of data.

Which of the following best describes a data-driven system?

a system that processes data, finds patterns and adapts

a method where decisions are made using patterns in large data sets

a system that follows predefined instructions or conditions

a subset of AI where systems improve as they process more data

Match the AI-related term with its definition.

A TV recommendation system that uses AI to suggest shows is an example of a {{ }} approach.

to slow down processing and make decisions more carefully

to identify patterns accurately and make better predictions

Why do AI systems require large amounts of data?
