> The Lloyd's [KMeans] algorithm takes initial centroids as its input. However, in case
the user doesn't provide the initial centers, they may ask for a particular initialization
scheme to be followed. The most commonly used are these:
> 1. Random initialization: Self-explanatory
> 2. kmeans++ initialization: http://ilpubs.stanford.edu:8090/778/1/2006-13.pdf
> 3. kmeans|| : http://theory.stanford.edu/~sergei/papers/vldb12-kmpar.pdf
> For very large data sets, or for large values of k, the kmeans|| method is preferred
as it provides the same approximation guarantees as kmeans++ and requires lesser number of
passes over the input data.
