Playground
Small interactive labs: iterate, measure, and see how the simulation changes.
K-means sandbox
Generate points, pick k, iterate, and watch inertia fall.
Open demo
Gradient descent lab
Tune learning rate and see convergence (or divergence) in real time.
Open demo
Gridworld MDP
Draw walls, add transition noise, and compute the optimal policy via value iteration.
Open demo
A/B inference simulator
Traffic, effect size, and Bayesian posterior.
