GitHub project 'Neural-Network-Visualisation' offers an interactive web tool to visualize a compact Multi-Layer Perceptron (MLP) trained on the MNIST dataset. Users can draw digits and watch activations propagate through the 3D network in real-time, along with prediction probabilities. The repo includes a Three.js frontend, exported weights, and a PyTorch training script.
