A map for exploring
How the ideas connect
The four labs show different forms of learning. Use this map to choose a question, then test it in a lab.
Four ways to explore learning
01Perceptron
How does one unit decide?
A handwritten digit becomes a set of signals. The learner weighs them, makes a decision and adjusts when it is wrong.
- Given
- Examples with right answers
- Changes
- Weights and a decision threshold
- Look for
- A mistake that changes the next decision

02Weather
What can examples reveal?
Compare a model taught with right answers against groups formed using measurements alone.
- Given
- Studied days, with or without answers
- Changes
- A fitted curve or group centres
- Look for
- How the two modes differ

03Student
What do layers add?
Several learning units work together to recognise more complicated patterns in an invented class.
- Given
- Student examples with grade bands
- Changes
- Connections between units
- Look for
- Studied versus unseen results
Try Student Lab ↗
04Rink
Can practice replace answers?
A skater chooses actions, sees the consequences and gradually learns which moves are worth trying.
- Given
- A rink and points for outcomes
- Changes
- The skater's memory of actions
- Look for
- How its best play changes
Try Rink Lab ↗
Carry one question across labs
Notice what changes
01Where does feedback come from?
The first three labs can use right answers. In the Rink Lab, the skater receives points after acting.
02What counts as learning?
Watch a weight, a curve, a group centre or a memory map change as the learner gets more experience.
03Will it work on something new?
Compare studied and unseen examples in Weather and Student. In Rink, change the goalie or the rink and retrain.
