AI glossary

Natural language processing (NLP) is the study of how AI systems can be used to process and generate human language. Currently, the focus is on neural networks and large language models (LLMs), which have great potential to generate fluent text in response to user prompts, as seen with ChatGPT.

A neural network is a computer system modeled on the structures of human and animal brains. They are called artificial neural networks (ANNs) to distinguish them from the biological neural networks that make up brains. A neural network consists of a collection of artificial "neurons" (based on neurons in biological brains) that send and receive signals to other neurons in the network. This structure allows the network to gradually learn to perform tasks more accurately. Neural networks are essential for large language models (LLMs) and other forms of deep learning.
