What is a neural network?

A neural network is a type of machine learning algorithm that is modeled after the structure and function of the human brain. A neural network consists of layers of interconnected nodes or neurons, with each node receiving input from the nodes in the previous layer and producing output that is passed to the nodes in the next layer.

The connections between the neurons are weighted, and the network learns by adjusting the weights to minimize the error between the predicted output and the actual output. Neural networks can be used for a variety of tasks, such as image and speech recognition, natural language processing, and time series prediction.
