Are dataSets shuffled?

VisualizationEarlyStoppingListener.java

		net.rnnClearPreviousState();
		trainDataIter.reset();
		
		INDArray pred = null;
		List<INDArray> predictionsTrain = new ArrayList<>();
		while (trainDataIter.hasNext()) {
			DataSet t = trainDataIter.next();
			INDArray featureMatrix = t.getFeatureMatrix(); // [miniBatchSize,inputSize,inputTimeSeriesLength], 5000x2x20 -> [3,5000,2,20,1,100000,5000,0,-1,99]
			INDArray predictionMiniBatch = net.rnnTimeStep(featureMatrix);
			normalizer.revertLabels(predictionMiniBatch);

			predictionsTrain.add(predictionMiniBatch);
			if (pred == null) {
				pred = predictionMiniBatch;
			} else {
				pred = Nd4j.concat(0, pred, predictionMiniBatch);
			}
		}
		trainDataIter.reset();
