Abstract: We consider the problem of finding statistically unusual subgroups in a multi-relation database, and extend previous work on single-relation subgroup discovery. We give a precise definition of the multi-relation subgroup discovery task, propose a specific form of declarative bias based on foreign links as a means of specifying the hypothesis space, and show how propositional evaluation functions can be adapted to the multi-relation setting. We then describe an algorithm for this problem setting ... (Update)
