How to perform K-means clustering with Python in Scikit?

Click for: original source

While deep learning algorithms belong to today’s fashionable class of machine learning algorithms, there exists more out there. Clustering is one type of machine learning where you do not feed the model a training set, but rather try to derive characteristics from the dataset at run-time in order to structure the dataset in a different way. It’s part of the class of unsupervised machine learning algorithms. By Christian Versloot.

k-means clustering is a method (…) that aims to partition n observations into k clusters in which each observation belongs to the cluster with the nearest mean (cluster centers or cluster centroid), serving as a prototype of the cluster.
