6 Best Free Online k-means Calculator Websites

Here are the best free online k-means calculator websites. k-means is a database clustering technique. It is known as k-means clustering. k-mean clustering is an unsupervised machine learning algorithm. This algorithm groups unlabeled datasets into different clusters. It places the datasets with similar characteristics into the same cluster. The number of clusters is pre-defined and represented by “k”. This technique is used to sort raw databases which can lead to the discovery of categories of groups. The algorithm randomly picks k-points or centroids. Then it binds each data point to its closest centroid. This process gets repeated iteratively with the re-assignment of data points until a model is formed.

A k-means calculator performs the k-means clustering. You can add your database to the calculator, select the number of clusters and run perform the calculator. This post covers 6 k-means calculators that you can use online for free. Some of these calculators come with additional options where you can confirm seeding methods, interactions, etc. These calculators also visually represent the clustering with graphs. You can go through the post to check these out in detail.
