public class BalanceToAvgFederatedScheme
extends DataPartitionFederatedScheme

Balance to Avg Federated scheme When the parameter server runs in federated mode it cannot pull in the data which is already on the workers. Therefore, a UDF is sent to manipulate the data locally. In this case the global average number of examples is taken and the worker subsamples or replicates data to match that number of examples. See the other federated schemes. Then all entries in the federation map of the input matrix are separated into MatrixObjects and returned as a list. Only supports row federated matrices atm.
