public class SpeechDetectorExperiment
extends Object
implements RunnableExperiment

An experiment for testing how good the trained speech detector is. It uses a stratified 10-fold cross-validation and uses a 1-k KNN annotator. The dataset is created during the setup() stage by the detector. The cross-validation uses the audio annotator delivered by the detector.

Constructor Detail

SpeechDetectorExperiment

public SpeechDetectorExperiment(SpeechDetector sd)

Takes the speech detector to test

Parameters:

sd - The speech detector to test

Method Detail

setup

public void setup()

Creates the datasets from which the validations will take place Setup of the experiment

Specified by:

setup in interface RunnableExperiment

See Also:

RunnableExperiment.setup()

perform

public void perform()

Uses a stratified 10-fold grouped cross-validation Perform the experiment

Specified by:

perform in interface RunnableExperiment

See Also:

RunnableExperiment.perform()

finish

public void finish(ExperimentContext context)

Description copied from interface: RunnableExperiment

Finalise the experiment, possibly writing the results, cleaning up, etc. The context gathered by the ExperimentRunner is provided so that RunnableExperiment implementations can access information for generating their reports.

Note that at the point the context is provided, it is not "locked" and is still recording. The ExperimentRunner returns a completed locked context after the experiment has been completely run.

Specified by:

finish in interface RunnableExperiment

Parameters:

context - the context provided by the ExperimentRunner

main

public static void main(String[] args)
                 throws IOException

Run this experiment.

Parameters:

args - The command-line arguments

Throws:

IOException
