🔢 Single Digit Recognition

How it works: Draw a digit using your mouse or touchscreen. The system uses 10 trained neural networks (one per digit) in an ensemble approach. All networks evaluate your drawing, and the one with highest confidence wins.

Technology: Pure JavaScript implementation of polynomial neural networks with 2D spatial features (neighborhoods and crosses). All inference runs locally in your browser.

Performance: ~97% accuracy on MNIST test data, ~5ms inference time per digit.
