Constructor Details

Fask

public Fask()

Constructor for Fask.

Fask

public Fask(ScoreWrapper score)

Constructs a new Fask object with the given ScoreWrapper.

Parameters:

score - the ScoreWrapper object to use

Method Details

runSearch

public Graph runSearch(DataModel dataModel,
 Parameters parameters)
                throws InterruptedException

Runs the Fask search algorithm on the given data model with the specified parameters.

Parameters:

dataModel - the data model to run the search on

parameters - the parameters for the search

Returns:

the resulting graph from the search

Throws:

IllegalStateException - if the data model is not a DataSet or if there are missing values

IllegalArgumentException - if there are missing values in the data set

InterruptedException

getComparisonGraph

public Graph getComparisonGraph(Graph graph)

Returns a comparison graph based on the true directed graph, if there is one.

Specified by:

getComparisonGraph in interface Algorithm

Parameters:

graph - The true directed graph, if there is one.

Returns:

A comparison graph.

getDescription

public String getDescription()

Returns a short, one-line description of the FASK algorithm. This description will be printed in the report.

Specified by:

getDescription in interface Algorithm

Returns:

A short description of the FASK algorithm.

Throws:

IllegalStateException - if the FASK algorithm is not initialized with either a test or an algorithm.

getDataType

public DataType getDataType()

Retrieves the data type of the dataset.

Specified by:

getDataType in interface Algorithm

Returns:

The data type of the dataset.

getParameters

public List<String> getParameters()

Returns the list of parameter names that are used by the algorithm. These parameters are looked up in the ParamMap, so if they are not already defined, they will need to be defined there.

Specified by:

getParameters in interface HasParameters

Returns:

The list of parameter names used by the algorithm.

getKnowledge

public Knowledge getKnowledge()

Retrieves the knowledge associated with this object.

Specified by:

getKnowledge in interface HasKnowledge

Returns:

The knowledge.

setKnowledge

public void setKnowledge(Knowledge knowledge)

Sets the knowledge associated with this object.

Specified by:

setKnowledge in interface HasKnowledge

Parameters:

knowledge - The knowledge object to be set.

setExternalGraph

public void setExternalGraph(Algorithm algorithm)

Sets the external graph to be used by the algorithm.

Specified by:

setExternalGraph in interface TakesExternalGraph

Parameters:

algorithm - The algorithm object.

getScoreWrapper

public ScoreWrapper getScoreWrapper()

Retrieves the ScoreWrapper object associated with this class.

Specified by:

getScoreWrapper in interface UsesScoreWrapper

Returns:

The ScoreWrapper object.

setScoreWrapper

public void setScoreWrapper(ScoreWrapper score)

Sets the score wrapper for the object.

Specified by:

setScoreWrapper in interface UsesScoreWrapper

Parameters:

score - the score wrapper to be set.
