How do I implement k-medoid clustering algorithms like PAM and CLARA in python 2.7? I am currently using Anaconda, and working with ipython 2.7. I have tried scipy.clusters but they don't seem to have the above algorithms. Please help
We cannot answer a question like yours. You need to have a concrete question, not "where do I start".
If you don't really want to implement it yourself, you may need to choose a different tool, such as ELKI or R or Matlab that do already include PAM and maybe CLARA, too.
Have you tried looking into Scikit learn? I have used been it quite a lot in ipython so can verify that it works well.
You can find all the documentation on their clustering algorithms here: http://scikit-learn.org/stable/modules/clustering.html#clustering
I don't exactly see something for k-medoid but maybe they have something there that can help.
Also, you can check out http://mlpy.sourceforge.net/. I have not used this package so cannot comment on how well it performs.
