Class ErrorOutput

java.lang.Object

stream.AbstractProcessor

stream.news.helper.ErrorOutput

All Implemented Interfaces:

stream.Processor, stream.StatefulProcessor

public class ErrorOutput
extends stream.AbstractProcessor

Compares a predicted label with the true label. If both labels match, no action is performed. If the prediction deviates from the true label, the number of the frame gets stored. This processor hence helps to get an overview of the data, that was not labeled correctly. This is helpful to improve the classifiers.
