Method Detail

generateGorillaDataset

public static MutableSequenceDataset<Label> generateGorillaDataset(int numCopies)

generateGorillaA

public static SequenceExample<Label> generateGorillaA()

generateGorillaB

public static SequenceExample<Label> generateGorillaB()

generateInvalidExample

public static SequenceExample<Label> generateInvalidExample()

This generates a sequence example with features that are unused by the training data.

Returns:

A SequenceExample which is invalid in the context of the Gorilla example data.

generateOtherInvalidExample

public static SequenceExample<Label> generateOtherInvalidExample()

This generates a sequence example where the first example has no features.

Returns:

A SequenceExample which is invalid as one example contains no features.

generateEmptyExample

public static SequenceExample<Label> generateEmptyExample()

This generates a sequence example with no examples.

Returns:

A SequenceExample which is invalid as it contains no examples.
