If you have a very large data set of $n$ vectors and you want to cluster them according to some metric measure, what is the current state of the art when you can not afford to do more than $\Theta(n)$ work? I am interested in methods that work well in practice as well as having nice theoretical properties.

A web search brings up "A sublinear time approximation scheme for clustering in metric spaces" by P. Indyk as the most cited paper in the area.

  • $\begingroup$ THere's also lots of work on sampling and streaming-based methods. These tend to work best when the metric is the Euclidean distance (or relatives). I'm not sure what your situation is. $\endgroup$ – Suresh Venkat Mar 7 '13 at 12:49
  • $\begingroup$ @SureshVenkat Weighted Euclidean distance works for me. I can find lists of papers, what I am not clear on is which are considered the current state of the art from an algorithms/practice point of view. $\endgroup$ – Majid Mar 7 '13 at 13:04

At the risk of sounding immodest, I wrote a short survey on stream clustering a few years ago. It's a little out of date, but not overly so, and doing forward citations will get you to the recent work in the area.

  • $\begingroup$ Thank you. I can see that people are very interested in streams. In my problem I have access to all the data, it is just very large. $\endgroup$ – Majid Mar 14 '13 at 9:30
