getDomain in class MultiLabelInfo

Returns:

The set of possible labels.

getID

public int getID(MultiLabel output)

Description copied from interface: ImmutableOutputInfo

Return the id number associated with this output, or -1 if the output is unknown.

Specified by:

getID in interface ImmutableOutputInfo<MultiLabel>

Parameters:

output - An output

Returns:

A non-negative integer if the output is known, or -1 if the output is unknown.

getOutput

public MultiLabel getOutput(int id)

Description copied from interface: ImmutableOutputInfo

Returns the output associated with this id, or null if the id is unknown.

id - A non-negative integer.

Returns:

An output object or null if it's unknown.

getTotalObservations

public long getTotalObservations()

Description copied from interface: ImmutableOutputInfo

Returns the total number of observed outputs seen by this ImmutableOutputInfo.

Specified by:

getTotalObservations in interface ImmutableOutputInfo<MultiLabel>

Returns:

The number of observed outputs.

getID

public int getID(String label)

Gets the id for the supplied label string.

Parameters:

label - The label string.
