- ogrisel 11y agoI agree it's useful although there also exists a more scalable approximate variant of classical k-Means and the new Yinyang k-Means (referenced in the paper), namely Mini-batch k-Means: http://www.eecs.tufts.edu/~dsculley/papers/fastkmeans.pdf http://www.eecs.tufts.edu/~dsculley/papers/fastkmeans.pdf This approximate method is implemented (at least) in sofia-ml and scikit-learn.
- thecopy 11y agoAnother approach is to transform the dataset into a smaller but representative dataset, called a core-set, and running k-means on that core-set instead which produces a "(1+e )-approximation for the optimal cluster centers".
