org.apache.flink.streaming.examples.ml.IncrementalLearningSkeleton.Predictor

All Implemented Interfaces:

Serializable, Function, CoMapFunction<Integer,Double[],Integer>

Enclosing class:

IncrementalLearningSkeleton

public static class IncrementalLearningSkeleton.Predictor
extends Object
implements CoMapFunction<Integer,Double[],Integer>

Creates prediction using the model produced in batch-processing and the up-to-date partial model.

By defaults emits the Integer 0 for every prediction and the Integer 1 for every model update.
