User: Can you explain the concept of artificial neural networks?
Assistant: Artificial neural networks (ANNs) are a type of artificial intelligence based on the structure of biological neural networks. ANNs are composed of layers of interconnected “neurons”, or processing elements, which receive a variety of inputs and produce a variety of outputs. Through the processing of data, ANNs are able to recognize patterns, identify trends and make predictions. By “learning” from example data and constantly adjusting their internal parameters, ANNs can accurately predict future outcomes based on past data. This ability has made ANNs essential for all kinds of applications, including facial, speech and character recognition; medical diagnosis and drones.
