K-Nearest Neighbors (K-NN) is one of the simplest machine learning algorithms. Like other machine learning techniques, it was inspired by human reasoning. For example, when something significant happens in your life, you memorize that experience and use it as a guideline for future decisions. Let us understand this with an example, you know and have seen a piece of glass break when it falls on ground. While the glass is falling, you’ve made the prediction that the glass will break when it hits the ground. But how can you do this?
