Class ExperimentOutputLayout

java.lang.Object

org.lenskit.eval.traintest.ExperimentOutputLayout

public class ExperimentOutputLayout
extends java.lang.Object

Manages the layouts for experiment output tables. Handles the common columns describing algorithms and data sets, and makes it easier to define new output tables that augment these columns with additional data.

Prefix a table for a particular algorithm and data set.

Parameters:

base - The table to prefix.

data - The data set to prefix for.

algorithm - The algorithm to prefix for.

Returns:

A prefixed table, suitable for outputting the results of evaluating algorithmInfo on data, or null if base is null.
