Interactive ML Tools
Explore the fundamental algorithms behind modern machine learning through interactive visualizations. No installs, no servers — everything runs in your browser.
Think of machine learning like teaching a child to recognize cats. You show them pictures, they guess, you correct them, and they get better over time. These three tools show you exactly how that learning happens inside a computer — the math, the steps, and the feedback loop — all with sliders and buttons you can play with. No coding required.
Neural Network Explorer
Visualize a 2-layer neural network in real time. Adjust weights, change activation functions (ReLU, Sigmoid, Tanh), and watch the forward pass propagate through every neuron.
Gradient Descent Lab
Watch gradient descent find minima on a loss surface. Click to set starting points, adjust learning rate, and see each optimization step with gradient arrows.
Backpropagation Visualizer
Step-by-step walk through forward and backward propagation in a 2→2→1 network. See every gradient computed via the chain rule with full mathematical derivation.
