Constructor Detail

TargetFeatureComputer

public TargetFeatureComputer(FeatureProcessorManager manager,
                     String featureProcessorNames)

Construct a TargetFeatureComputer that knows how to compute features for a Target using the given set of feature processor names. These names must be known to the given Feature processor manager.

Parameters:

manager - manager

featureProcessorNames - a String containing the names of the feature processors to use, separated by white space, and in the right order (byte-valued discrete feature processors first, then short-valued, then continuous)

Method Detail

getFeatureDefinition

public FeatureDefinition getFeatureDefinition()

Provide the feature definition that can be used to interpret the feature processors generated by this TargetFeatureComputer.

Returns:

featureDefinition

computeFeatureVector

public FeatureVector computeFeatureVector(Target target)

Using the set of feature processors defined when creating the target feature computer, compute a feature vector for the target

Parameters:

target - target

Returns:

a feature vector for the target

toStringValues

public String toStringValues(FeatureVector features)

For the given feature vector, convert each encoded value into its string representation.

Parameters:

features - a feature vector, which must match the feature processors known to this feature computer.

Returns:

a string in which the string values of all features are separated by spaces.

Throws:

IllegalArgumentException - if the number of byte-valued, short-valued or continuous elements in features do not match the set of feature processors in this feature computer.

getByteValuedFeatureProcessors

public ByteValuedFeatureProcessor[] getByteValuedFeatureProcessors()

getShortValuedFeatureProcessors

public ShortValuedFeatureProcessor[] getShortValuedFeatureProcessors()

getContinuousFeatureProcessors

public ContinuousFeatureProcessor[] getContinuousFeatureProcessors()

getAllFeatureProcessorNames

public String getAllFeatureProcessorNames()

List the names of all feature processors. The first line starts with "ByteValuedFeatureProcessors", followed by the list of names of the byte-valued feature processors; the second line starts with "ShortValuedFeatureProcessors", followed by the list of names of the short-valued feature processors; and the third line starts with "ContinuousFeatureProcessors", followed by the list of names of the continuous feature processors.

Returns:

a string with the names.

getByteValuedFeatureProcessorNames

public String getByteValuedFeatureProcessorNames()

List the names of all byte-valued feature processors, separated by space characters.

Returns:

a string with the names.

getShortValuedFeatureProcessorNames

public String getShortValuedFeatureProcessorNames()

List the names of all short-valued feature processors, separated by space characters.

Returns:

a string with the names.

getContinuousFeatureProcessorNames

public String getContinuousFeatureProcessorNames()

List the names of all byte-valued feature processors, separated by space characters.

Returns:

a string with the names.

getAllFeatureProcessorNamesAndValues

public String getAllFeatureProcessorNamesAndValues()

List the names and values of all feature processors. The section describing the byte-valued feature processors starts with the string "ByteValuedFeatureProcessors" in a line by itself, followed by the list of names and values of the byte-valued feature processors, as described in getByteValuedFeatureProcessorNamesAndValues(). The section describing the short-valued feature processors starts with the string "ShortValuedFeatureProcessors" in a line by itself, followed by the list of names and values of the short-valued feature processors, as described in getShortValuedFeatureProcessorNamesAndValues(). The section describing the continuous feature processors starts with the string "ContinuousFeatureProcessors" in a line by itself, followed by the list of names and values of the continuous feature processors, as described in getContinuousFeatureProcessorNamesAndValues().

Returns:

a string with the names and values.

getByteValuedFeatureProcessorNamesAndValues

public String getByteValuedFeatureProcessorNamesAndValues()

List the names of all byte-valued feature processors and their possible values. Each line starts with the name of a feature processor, followed by the full list of string values, separated by space characters. The values are ordered so that their position corresponds to the byte value.

Returns:

a string with the names and values.

getShortValuedFeatureProcessorNamesAndValues

public String getShortValuedFeatureProcessorNamesAndValues()

List the names of all short-valued feature processors and their possible values. Each line starts with the name of a feature processor, followed by the full list of string values, separated by space characters. The values are ordered so that their position corresponds to the short value.

Returns:

a string with the names and values.

getContinuousFeatureProcessorNamesAndValues

public String getContinuousFeatureProcessorNamesAndValues()

List the names of all continuous feature processors and their possible values. Each line starts with the name of a feature processor, followed by the value "float" to indicate that the list of possible values is not limited.

Returns:

a string with the names and values.

getPauseSymbol

public String getPauseSymbol()

Get the pause symbol as associated with the "phone" feature processor used.

Returns:

pauseSymbol
