KMeansMaster (guagua-examples 0.7.10 API)

java.lang.Object
- ml.shifu.guagua.example.kmeans.KMeansMaster

All Implemented Interfaces:

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.
