Neural Network, A Neural Network is a computational model inspired by the structure of the human brain, consisting of interconnected layers of artificial "neurons" that process and transmit information. It adjusts the network's weights, or parameters that influence the network's output and performance, to minimize errors and improve accuracy. They are called “neural” because they mimic how neurons in the brain signal one another. For instance, you can generate new images from an existing image database or original music from a database of songs. These models consist of interconnected nodes or neurons that process data, learn patterns and enable tasks such as pattern recognition and decision making. A neural network is a machine learning model that stacks simple "neurons" in layers and learns pattern-recognizing weights and biases from data to map inputs to outputs. Their creation was inspired by biological neural circuitry. Next, the network is asked to solve a problem, which it attempts to do over and over, each time strengthening the connections that lead to success and diminishing those that lead to failure.
