The global k-means clustering algorithm
Résumé
We present the global k-means algorithm which is an incremental approach to clustering that dynamically adds one cluster at a time through a deterministic global search procedure consisting of N (with N being the size of the data set) executions of the k-means algorithm from suitable initial positions. We also propose modifications of the methods to reduce the computational load without significantly affecting solution quality. The proposed clustering methods are tested on well-known data sets and they compare favorably to the k-means algorithm with random restarts.
