Abstract:

The $k$-means problem is a classic NP-hard problem in clustering analysis. If somedata points are allowed not to be clustered but to pay some penalty, the $k$-means problem with penalty is induced. In this paper, weextend the $k$-means problem with penalty from Euclidean distance tothe more general $\mu $-similar Bregman divergences, and study theinitialization algorithm for the $\mu $-similar Bregman divergences $k$-means problem with penalty. The seeding algorithm is given wherethe approximation ratio is only related to $\mu $ and the ratio ofthe maximum value to the minimum value of the data point penalty.
