Customizable Neural Network Training and Prediction (Animations + Formulas + Loss/Activation Functions) Customizable Neural Network Training and Prediction This example demonstrates a multi-layer neural network where you can customize the network structure, activation functions, and loss functions as needed. Both training and prediction are shown with animations illustrating forward propagation (with back propagation update during training), accompanied by formulas and statistical information. In-depth Understanding of Neural Network Basic Elements and Calculation Methods In this example, we introduce the core components of a neural network—parameters and hyperparameters—and explain how they function in model computation and practical applications. Parameters Parameters refer mainly to the weights and biases within the network. During forward propagation, input data is computed as: a = activa...
