所有已实现的接口：

ml.shifu.guagua.master.MasterComputable<KMeansMasterParams,KMeansWorkerParams>

public class KMeansMaster
extends Object
implements ml.shifu.guagua.master.MasterComputable<KMeansMasterParams,KMeansWorkerParams>

KMeansMaster computes new k center points for next iteration.

By accumulating all the k center points sum values from all workers, then average to get new k center points.
