Describe the workflow you want to enable

Hi,
I was wondering if there is—or has been—any initiative to support cosine similarity in the KMeans implementation (i.e., spherical KMeans). I find the algorithm quite useful and would be happy to propose an implementation. The addition should be relatively straightforward.

Describe your proposed solution

Enable the use of cosine similarity with KMeans or implement a separate SphericalKMeans class.

Describe alternatives you've considered, if relevant
