Forward and Backward propagation in Convolutional Neural Networks

Theory and code

Introduction

If you are here you have definitely heard about Convolutional Neural Networks and perhaps you are now trying to understand how they work under the hood. In this case this article should help you to get your head around how forward and backward passes are performed in CNNs by using some visual examples.
I assume that you are familiar with padding and strides in CNNs and have some basic understanding of backpropagation and the chain …
