Neural Network
A computational model inspired by the brain, composed of interconnected layers of nodes that process data.
Also: ANN
Definition
An artificial neural network (ANN) is a computational model inspired by the structure and function of biological neural networks in the human brain. It consists of layers of interconnected nodes (neurons): an input layer, one or more hidden layers, and an output layer. Each connection has a weight that is adjusted during training using backpropagation to minimize prediction error. Neural networks excel at learning complex patterns in high-dimensional data such as images, text, and audio.
Example
“A neural network trained on millions of chest X-rays learns to detect pneumonia by identifying subtle visual patterns across thousands of pixel values simultaneously.”
