AI Glossary / Neural network

🧠 Basics

A neural network is a computational model loosely inspired by brain structure: it consists of layers of connected "neurons," each performing a simple mathematical operation. The network's power comes from the number of connections - during training their weights are adjusted so the whole system performs the task better and better. Deep neural networks (with many layers) underpin almost everything we call AI today: from speech recognition to image and text generation. Large language models are essentially gigantic neural networks with billions of parameters.
