The languages of Data Science  For anyone just getting started on their data science journey, the range of technical options can be overwhelming. There is a dizzying amount of choice when it comes to programming languages. Each has its own strengths and weaknesses and there is no one right answer to the question of which one you should […]

Let’s understand some of the factors that can impact the final clusters that you obtain from the K-means algorithm. This would also give you an idea about the issues that you must keep in mind before you start to make clusters to solve your business problem. Thus, the major practical considerations involved in K-Means clustering […]

Let’s go through the K-Means algorithm using a very simple example. Let’s consider a set of 10 points on a plane and try to group these points into, say, 2 clusters. So let’s see how the K-Means algorithm achieves this goal. [Note: If you don’t know what is meant by Euclidean distance, you’re advised to […]

The next concept that is crucial for understanding how clustering generally works is the idea of centroids. If you remember your high school geometry, centroids are essentially the centre points of triangles. Similarly, in the case of clustering, centroids are the center points of the clusters that are being formed.   Now before going to the […]

Euclidean Distance In the previous segments, you got an idea about how clustering works – it groups the objects on the basis of their similarity or closeness to each other.   Now, the next important thing is to get into the nitty-gritty of how clustering algorithms generally work. You will learn about the 2 types of […]
