Convolutional layer applies a convolution operator on the input data using a filter and produces an output that is called feature map.The purpose of the convolution operation is to extract the high-level features such as edges, from the input image. Convolutional neural networks (or ConvNets) are biologically-inspired variants of MLPs, they have different kinds of layers and each different layer works different than the usual MLP layers. The diagram indicates the binary values and polynomial form, indicating the left-most bit is the most-significant-bit (MSB). What the max-pooling layers do is provide some translation invariance as @Matt points out. 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.In a convolutional neural network, the hidden layers include layers that perform convolutions. Stride is a parameter of the neural network's filter that modifies the amount of movement over the image or video. This allows the network to take in 2D inputs of arbitrary size and return an output of the same size, where each pixel is a prediction for its corresponding pixel in the input image. This is the key that makes Convolutional Neural Networks so efficient. ... Let us go over one of the code lines so that the meaning of this entire model building segment is intuitively clear. Third, a universal dictionary is learned to represent all images, reducing the model repre-sentation flexibility.
