Deep learning
By HubAI editorial team · Source checked: 24 October 2026What does it mean?
Machine learning using neural networks with multiple layers. Those layers learn representations of the input, such as features useful for recognising an image or predicting the next token.
Picture this
An image system learns from many labelled pictures rather than being given a hand-written rule for every possible outline of a bicycle.
Where you’ll come across it
Speech recognition, computer vision and many modern language models. You rarely need to choose the number of layers when buying an everyday AI app.
What it doesn’t mean
Deep does not mean more thoughtful. A large network can still make confident mistakes, and its internal representations are not a plain-English explanation of its decisions.
Choose the task before the tool
A short exercise · use fictional or non-sensitive material.
- Pick one small job you already know how to do, such as turning rough notes into an agenda.
- Write down what a useful result must include. Use fictional notes for your first attempt.
- Compare the result with your checklist and count the changes you still need to make.
