K-Nearest Neighbors – the Laziest Machine Learning Technique

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 me give you a scenario of a person dropping a glass. While the glass is falling, you've made the prediction that the glass will break when it hits the ground.
