We have seen in previous article, how limitations of ANN in dealing with spatial data i.e images led to conception of CNNs, inspired by visual cortex of human eye. Now, there is a need to visualize how CNNs work in reality. The true fascination lies in understanding how these systems actually work, how they learn, and what they “see.”

This article interprets inner workings of CNN, how it’s mathematics shape intelligence from images and how it is trained to look for right aspects in a picture.

Limitations of ANNs: Move to Convolutional Neural Networks

At the heart of every CNN, there is a deceptively simple operation that traditional neural networks simply cannot match: convolution. This mathematical procedure gives CNNs their name — and their extraordinary power.

Convolution is a mathematical operation in which a smaller matrix is multiplied to various parts of a larger one and the resultant matrix is taken as a downsized version of large matrix. Consider the example below:
