A heuristic approach to effective and efficient clustering on uncertain objects

作者:

Highlights:

• We reduce UK-means to K-means.

• We experimentally show that K-means performs much faster than existing pruning algorithms.

• We propose Approximate UK-means to heuristically identify boundary objects and re-assign them to better clusters.

• We propose three models for the representation of cluster representative. To our knowledge, this is the first time to introduce uncertain model of cluster representative.
