Convolutional neural networks

A lot of work has been done over the years in using neural networks to perform image recognition, and along the way, a technique called the convolutional neural network was developed to provide a better method of identifying features in images. This technique works by running a convolution step across the image, as shown in the following diagram:

CNN operation extracting features from an image

What is happening here is that a convolution matrix set by stride is multiplied across the image using a convolution step in order to generate a feature map. We do this in order to isolate features in an image by isolating ...
