Deep Neural Network (DNN), also called Deep Nets, is a neural network with a certain level of complexity. It can be considered as stacked neural networks, or networks composed of several layers, usually two or more, that include input, output, and at least one hidden layer in between.
DDNs are often employed to deal with unlabeled and unstructured data. Today, these sophisticated neural networks have become the standard tool for solving various computer vision tasks.
