------------------------------
bq. Please assign the ticket to me
The JIRA config does not allow it...
Anyways, your commitment is duly noted here. ;)
> Implement cKMeans as a clustering algorithm
> -------------------------------------------
>
> Key: MATH-1435
> URL: https://issues.apache.org/jira/browse/MATH-1435
> Project: Commons Math
> Issue Type: New Feature
> Reporter: Shubham Jindal
>
> 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. It is
> supposed to be one of the best clustering algorithms for clustering 1D points
