A neural network is a model in artificial intelligence that processes information in several stages.
It consists of many connected units often called artificial neurons. These units are organized in layers.
During training, the network receives many examples and adjusts the connections between its neurons so that it can recognize patterns more accurately.
Neural networks are used in many modern technologies such as image recognition, speech recognition, and language translation.
They are especially useful when data is complex and simple rule-based approaches are not sufficient to produce accurate results.
