neural network

Neural networks are used in predictive modeling. Their construction is based loosely on human biology. They are constructed of a series of algorithms that each carries out its own specific operation on the data, then passes its results to the next layer, until an output layer is reached and a final output or prediction is made. Neural networks can be used on many kinds of data, but complex networks with many layers are most used in deep learning for challenging data like images, video, and text.
