k*-Means — A Generalized k-Means Clustering Algorithm with Unknown Cluster Number

2002
This paper presents a new clustering technique named STepwise Automatic Rival-penalized (STAR) k-means algorithm (denoted as k*-means), which is actually a generalized version of the conventional k-means (MacQueen 1967). Not only is this new algorithm applicable to ellipse-shaped data clusters rather than just to ball-shaped ones like the k-means ...

Clustering by k-means

2009
Clustering techniques are used for finding suitable groupings of samples belonging to a given set of data. There is no knowledge a priori about these data. Therefore, such set of samples cannot be considered as a training set, and classification techniques cannot be used in this case.
