Neural Networks Explained: How They Work and Why They Matter

A neural network is a machine-learning model built from layers of connected computational units. These units transform numerical inputs using learned weights, biases, and nonlinear functions so the network can approximate useful relationships in data. Google’s current Machine Learning Glossary provides a useful technical reference for neural-network, neuron, activation-function, and backpropagation terminology. Neural networks power […]
