Convolutional neural networks are distinguished from other neural networks by their superior performance with image, speech, or audio signal inputs. They have three main types of layers, which are: Convolutional layer. Pooling layer. Fully-connected (FC) layer. The convolutional layer is the first layer of a convolutional network A convolutional neural network consists of an input layer, hidden layers and an output layer. In any feed-forward neural network, any middle layers are called hidden because their inputs and outputs are masked by the activation function and final convolution Convolution is a particular type of regularization that exploits the linear dependence of features or observations. This, in turn, lets us decrease the noise and restore consistency with the prior assumption on linear independence of the features, as we'll see shortly
