Class ExecutionInfo

java.lang.Object

org.grouplens.lenskit.eval.ExecutionInfo

All Implemented Interfaces:

Serializable

@Shareable
public class ExecutionInfo
extends Object
implements Serializable

Bean containing information about a data set. Used to provide that information to the algorithmInfo, if it needs it for some reason. It is best avoided, but can be useful in certain experimental setups. The evaluators inject it into the configuration, so it is available via DI.

Since:

1.1

Method Detail

getAlgoName

public String getAlgoName()

Get the algorithmInfo name.

Returns:

The algorithmInfo name.

getAlgoAttributes

public Map<String,Object> getAlgoAttributes()

Get the algorithmInfo attributes.

Returns:

The algorithmInfo attributes.

getDataName

public String getDataName()

Get the data set name.

Returns:

The data set name.

getDataAttributes

public Map<String,Object> getDataAttributes()

Get the data set attributes.

Returns:

The data set attributes.

getDataSet

public TTDataSet getDataSet()

Get the active train-test data set. Note that this method provides access to the test data, enabling an algorithm to cheat. Be careful not to cheat.

Returns:

The active train-test data set.
