I once wrote a kNN classifier in J (see this thread: http://www.jsoftware.com/pipermail/chat/2014-June/006063.html).
Further on, I also wrote some other machine learning tools like a k-means clustering, self-organising map, laplacian eigenmaps etc. which I can't immediately find back. I remember finding the implementation in J easier to write (maybe not easier to read) than for instance in Matlab :) I'm curious to see what you come up with.
