![]() ![]() Manhattan Distance: Often referred to as the city block metric, in this the distance between two points is the absolute differences of their Cartesian coordinates and is used in case of high dimensionality.This is analogous to how the KNN classification algorithm works. Using these features we can determine the class to which a ball belongs. In order to differentiate if either the ball is made of Gold or Carbon you can check its Colour, Electrical Conductivity, Boiling Point and Melting Point. Suppose that you randomly select a ball from a bag full of metal balls that are either made of Gold or Carbon. The PDF copy of this article can be downloaded from here to continue your learning offline. Also if you like this article, do consider clapping for this article and make sure to follow me for more Machine Learning Recipes. Then I will try to break down certain important terms in affinity with this algorithm and finally by the end of this article, we will be designing our very own classifier using KNN algorithm.īefore starting this article, I would recommend you to take a look at my previous articles where I have discussed about various learning algorithms. In this article I will first try to give you an intuition of what the algorithm is, and how it makes predictions. ![]() This algorithm can be used for dealing with both regression and classification problems in ML. In this article, I will be focusing on one of the most sophisticated learning algorithm known as K Nearest Neighbour. A Step by Step Approach to Build a KNN ClassifierĪs machine learning practitioners, we come across a wide array of machine learning algorithms that we may exert to build a particular predictive model. ![]()
