While Gradient Descent isn’t traditionally thought of as a machine-learning algorithm, understanding gradient descent is vital* *to understanding how many machine learning algorithms work and are optimized. Understanding Gradient Descent might require a brief knowledge of Calculus, but I have tried my best to keep it as simple as possible.

Nowadays, the buzz is around these magical tools called ‘Machine Learning’ and ‘Deep Learning’. But for an average human with no computer science background it is just that magic. Possibility is that you are using it in one way or the other and you don’t even know about it.
