Constructor Details

DatasetViewProvenance

public DatasetViewProvenance(Map<String,com.oracle.labs.mlrg.olcut.provenance.Provenance> map)

Deserialization constructor.

Parameters:

map - The provenances.

Method Details

generateBootstrap

public int[] generateBootstrap()

Generates the indices from this DatasetViewProvenance by rerunning the bootstrap sample. Note these indices are invalid if the view is a weighted sample, or not sampled.

Returns:

The bootstrap indices.

isSampled

public boolean isSampled()

Is this view from a bootstrap sample.

Returns:

True if it's a bootstrap sample.

isWeighted

public boolean isWeighted()

Is this view a weighted bootstrap sample.

Returns:

True if it's a weighted bootstrap sample.

equals

public boolean equals(Object o)

Overrides:

equals in class DatasetProvenance

hashCode

public int hashCode()

Overrides:

hashCode in class DatasetProvenance

allProvenances

protected List<com.oracle.labs.mlrg.olcut.util.Pair<String,com.oracle.labs.mlrg.olcut.provenance.Provenance>> allProvenances()

Description copied from class: DatasetProvenance

Returns a list of all the provenances.

Overrides:

allProvenances in class DatasetProvenance

Returns:

The provenances.

toString

public String toString()

This toString doesn't put the indices in the string, as it's likely to be huge.

Overrides:

toString in class DatasetProvenance

Returns:

A string describing this provenance.
