K-Means Clustering Algorithm

This is an implementation of K-Means clustering algorithm along with the K-Means++ seeding technique using NumPy. Further, a comparison of the manual implementation is made against the SK Learn implementation of the algorithm. The Iris dataset is used for this comparison.
