If you have read my previous articles, you’ll know what’s coming next. In this part of the internet, we take complex-sounding concepts and make them fun and nbd by illustrating them. And if you haven’t read my previous articles, I highly recommend you start with my series of articles covering the basics of machine learning because you’ll find that a lot of the material covered there is relevant here.

Today, we’re going to tackle the big boy — Neural Networks. This is just the first article in a whole series I plan on doing on Deep Learning. It will focus on how a simple artificial neural network learns and provide you with a deep (ha, pun) understanding of how a neural network is constructed, neuron by neuron, which is super essential as we’ll continue to build upon this knowledge. While we will dive into the mathematical details, there’s no need to worry because we will break down and illustrate each step. By the end of this article, you’ll realize that it’s waaaaay simpler than it sounds.

But before we explore that, you might be wondering: Why do we need neural networks? With so many…
