22.2 How to Apply K-Means Clustering Algorithm

Suppose we have 8 data points on a graph.Our goal is to group these points into clusters using the K-Means algorithm. Step 1: Choose the Number of Clusters (K) First, we decide how many clusters we

When the Machine Finds Patterns You Didn't Tell It to Look For

This is Week 19 of my data science journey, the week I stopped telling the algorithm what to find and started letting it discover patterns on its own. If you've been following since Week 18, welcome b

Day 17: K-Means Clustering – Discovering Hidden Groups in Data

K-Means is one of the simplest and most popular clustering algorithms.It finds groups in your data, and every point belongs to one of these groups (called clusters). Before we dive into K-Means, let's first set the stage. In supervised learning, you ...
