Introduction Convolutional neural networks (or convnets for short) are used in situations where data can be expressed as a "map" wherein the proximity between two data points indicates how related they are. A unified deep neural network, denoted the multi-scale CNN (MS-CNN), is proposed for fast multi-scale object detection. data. An image is such a map, which is why you so often hear of convnets in the context of image analysis. See the section below on Pooling for more details on max pooling).

IIT Ropar When we see something, we label every object based on what we have learned in the past. In many cases, we will want to set \(p_h=k_h-1\) and \(p_w=k_w-1\) to give the input and output the same height and width. It explains the theory involved with the different variants used in practice and also, gives a big picture of the whole network by putting everything together. This will make it easier to predict the output shape of each layer when constructing the network. Here, max pooling chooses the highest pixel value in a 2 2 patch translated in increments of 2 pixels.
