How an algorithm behind Deep Learning works

There are many algorithms behind Deep Learning (see this comparison of deep learning frameworks for details), but one common algorithm used by many frameworks is Convolutional Neural Networks (CNNs). The mathematics behind that algorithm are complex, but Brandon Rohrer explains the process in plain language, and shows how AIs trained with CNNs can appear to mimic human processes like vision:
