I am trying to form clusters around medoids using PAM algorithm in R. Is there anyway of fixing the cluster size for PAM (somewhat bruteforce the cluster size) ? Are there any other clustering algorithms that will provide equal sized clusters for medoids ?
Thank you in advance for your help.
You can modify a clustering algorithm to suit your needs.
You can follow this Tutorial for Same-Size K-Means, or simply use this algorithm from the tutorial package/module in ELKI (build the latest version from GitHub, because I just fixed a bug there - this will be included in ELKI 0.7.2).
Essentially, this algorithm performs a k-means style least-squares optimization, but all clusters must have the same size (if N/k is not integer, the cluster sizes may vary by 1).
If you go to above tutorial and scroll to the bottom, you can see example results.
