Surely you have heard of clustering as a way to help organising data into different groups depending on the features at hand. Clustering algorithms are part of unsupervised machine learning. In my post in the Domino Data Science Blog I cover the basics of K-means, take a look and you can even get to play with some code by trying the Domino platform. What is not to like‽
You can also take a look at my Data Science and Analytics with Python books (here and here) for more information.
