Class SkipGramTrainer

java.lang.Object

org.nd4j.parameterserver.distributed.training.BaseTrainer<SkipGramRequestMessage>

org.nd4j.parameterserver.distributed.training.impl.SkipGramTrainer

All Implemented Interfaces:

TrainingDriver<SkipGramRequestMessage>

public class SkipGramTrainer
extends BaseTrainer<SkipGramRequestMessage>

Distributed SkipGram trainer TrainingDriver idea is simple: 1) We get request from Client 2) We initiate training by issuing DotRequest 3) Each Shard does Dot accumulation 4) As soon as Dot aggregated, we calculate gradients independently 5) As soon as they are ready - we just apply them to appropriate
