Neural Network Trainer
Choose some data, build a network and watch it learn. This is a real multilayer perceptron trained by backpropagation in your browser: you can see the decision boundary take shape, the loss fall and every weight change.
What you can do
- Up to 4 hidden layers of up to 8 units, trained live in the browser
- Circles, XOR, spirals, moons and clusters, with adjustable noise
- Decision boundary drawn as it changes
- Training and test loss, with test points held back
- Connection weights drawn by thickness and coloured by sign
