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. Here, max pooling chooses the highest pixel value in a 2 2 patch translated in increments of 2 pixels. IIT Ropar Features of a convolutional layer. A convolution is essentially sliding a filter over the input. ۲۰۱۷ ImageNet Classification with Deep Convolutional Neural Networks. In this step, we will touch on feature detectors, which basically serve as the neural network's filters.
