Distance in Machine Learning -- a prominent element!

It is no surprise that Machine Learning uses a lot of Mathematics into the implementation of its algorithms and models, and along it with comes some serious coordinate geometry. The coordinate geometry brings with itself distances, and that is what we will address today! Be it Physics, Geography, Nuclear Physics, or any kind of science, the word distance has always been familiar and therefore, we all have a basic understanding of what distance is. It's a numerical measurement of how far two objects or points are. Well, I'm here to give you it of a twist! Your life has been a lie because the distance is not exactly what we know in Machine Learning.
