Small browser experiments that let you poke at how models learn. Pick one to open it.

Signal Lab: a small neural network drawn as nodes and weighted wires
Neural networks

Signal Lab

A neural network you tune by hand. Drag weights and biases to make it add, multiply or divide two 2-bit numbers, or let it train itself.

 Regression Explorer: data points with a fitted curve next to a cost landscape with a gradient descent path
Gradient descent

Regression Explorer

Place data points and watch gradient descent fit a linear, logistic or ReLU model, or a logistic classifier, with the cost landscape alongside.

 Curse of Dimensionality Explorer: a 3D cost volume, 2D and 1D slices, and a convergence chart
Optimization

Curse of Dimensionality

Run gradient descent or random search on cost functions with up to 10 dimensions, and see through 3D, 2D and 1D slices how much faster the search space grows.
