Interactive Neural Network Engine
Neural Network Visualization
Configure hidden layers, train on real datasets, and observe forward propagation and backpropagation step by step in real time.
Direct Answer: What is the Neural Network Visualizer?
The Neural Network Visualizer is an interactive educational sandbox where you can build multi-layer perceptron (MLP) architectures, adjust hidden neurons, select activation functions (ReLU, GELU, Sigmoid, Tanh), and step through gradient backpropagation (gradient updates dL/dW) live on synthetic classification data or user-drawn MNIST digits.
