A connectionist expert system, also known as a neural network expert system, is a type of artificial intelligence technology that simulates the way neurons in the brain work. It is designed to learn from data and improve its performance over time. Synonyms for this technology include neural expert system, neurocomputing expert system, and artificial neural network. Some other related terms include deep learning, machine learning, and cognitive computing. These all refer to technologies that use algorithms and data to learn and make decisions like a human brain would. Connectionist expert systems are increasingly being used in fields such as healthcare, finance, and manufacturing to improve decision-making and automate complex tasks.
