AI and the Mind · Interactive field guide

Make learning visible.

Four hands-on labs take you from one artificial neuron to a network, a model of weather, and an agent learning through practice. Change one thing. See what changes. Work out why.

01 · Follow a short pathEach lab offers four guided steps, from first observation to deeper questions.

02 · Try the live modelAdjust inputs and settings; every simulation remains fully explorable.

03 · Explain what happenedOpen the context notes when you want the reasoning behind a result.

The labs

Start anywhere. Each lab begins with a guided path and opens into a full experiment when you are ready.

01A single decision

Start with the mechanism

Perceptron Lab

Watch one learning unit inspect handwriting, add evidence and adjust after a mistake.

Open the lab
02Learning from data

Compare two approaches

Weather Lab

Fit a curve to studied days, then group weather patterns without giving the machine answers.

Open the lab
03Layers and learning

Build on a single unit

Student Lab

Train a neural network on an invented class and see what its layers learn to recognise.

04Learning by doing

Change the kind of feedback

Rink Lab

Help a skater learn from attempts, rewards and mistakes as it tries to score.

A question to carry through

What actually changes when a model learns?

In Perceptron and Student, inspect changing weights. In Weather, compare a curve on studied and unseen days. In Rink, watch experience become a choice of action. The labs show different kinds of learning, but the same habit of inquiry helps in each: predict, test and explain.

Choose an experiment

Go at your own pace

Guidance when you want it.

Use the four-step path to find your bearings. Open the short explanations next to a graph or control when you need more context. The full set of settings and experiments is always there.
