Constructor Details

NoisyInterlockingCrescentsDataSource

public NoisyInterlockingCrescentsDataSource(int numSamples,
 long seed,
 double variance)

Constructs a noisy interlocking crescents data source.

It's the same as InterlockingCrescentsDataSource but each point has Gaussian noise with zero mean and the specified variance added to it.

Parameters:

numSamples - The number of samples to generate.

seed - The RNG seed.

variance - The variance of the Gaussian noise.

Method Details

postConfig

public void postConfig()

Used by the OLCUT configuration system, and should not be called by external code.

Specified by:

postConfig in interface com.oracle.labs.mlrg.olcut.config.Configurable

Overrides:

postConfig in class DemoLabelDataSource

generate

protected List<Example<Label>> generate()

Description copied from class: DemoLabelDataSource

Generates the examples using the configured fields.

Is called internally by DemoLabelDataSource.postConfig().

Specified by:

generate in class DemoLabelDataSource

Returns:

The generated examples.

toString

public String toString()

Overrides:

toString in class Object
