Inspired by the biological network of neurons, a neural network is an information-processing system that powers artificial intelligence.

Like the brain's neurons, a neural network is composed of interconnected nodes organized in layers. These nodes process information and learn by adjusting the strength of their connections. This allows the network to identify complex patterns and features in vast datasets. For example, a neural network can learn to recognize a face in a photograph or a specific word in a spoken sentence without being explicitly programmed for it.
