Shubham Jindal updated MATH-1435:
---------------------------------
Description:
cKMeans implementation has been described here
https://cran.r-project.org/web/packages/Ckmeans.1d.dp/index.html and
https://journal.r-project.org/archive/2011-2/RJournal_2011-2_Wang+Song.pdf
The algorithm described here is O(kn^2) where k: number of clusters and n:
number of 1D points. But, there exists an efficient implementation in later
versions of cKMeans which is O(knlogn)
cKMeans is faster than kMeans and also deterministic in nature. cKMeans is
supposed to be one of the best clustering algorithms for clustering 1D points
