# Package com.tibco.patterns.learn.recpair

Management of datasets of record pairs, calculation of feature scores for record pairs.

A number of record pairs can be grouped together in a RecPairSet dataset. A Training dataset and a Validation dataset can be grouped together as a RecPairExperiment.

If only the record keys are available, then a running instance of ibi Patterns server must be used to calculate feature scores for the record pairs. This is done by a RecPairScorer object, which uses RLinkServerInterface to communicate with the server.
