Introduction

In this lesson, we will introduce the hot cake of the field of Machine Learning. Neural Networks are models designed based on our brains. Human brains have about 86 billion cells connected together by synapses. A neural network also has many cells/units that are connected to one another. Whenever an input is given, it is propagated through the entire network of cells, reaching the output cells where certain actions are handled for certain outputs.

This lesson will help you build a neural network from scratch. Later, we will introduce TensorFlow which is the de facto standard for neural networks. So let's get started.
