OffsetFeatureConjunction

public OffsetFeatureConjunction(java.lang.String thisFeatureName,
                                java.lang.String[] featureNames,
                                int[] offsets,
                                boolean[] isNonNegated,
                                boolean tagAllTimesteps)

Create a Pipe for adding conjunctions of specified features.

Parameters:

thisFeatureName - Name of this conjunction feature.

featureNames - String giving name for each subfeature i.

offsets - For each subfeature i, which offset from the current timestep must i appear at.

isNonNegated - If element i is false, then the negation of the feature is added to the conjuction.
