human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge groups papers that share a common citing paper.

Details of the hypergraph:
Center hyperedge (induced by source paper "Relational Knowledge Discovery in Databases"):
  Abstract: In this paper, we indicate some possible applications of ILP or similar techniques in the knowledge discovery field, and then discuss several methods for adapting and linking ILP-systems to relational database systems. The proposed methods range from "pure ILP" to "based on techniques originating in ILP". We show that it is both easy and advantageous to adapt ILP-systems in this way.

Includes members:
  Member "Inductive Constraint Logic":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "Applications of a logical discovery engine")
  Member "Inverse entailment and Progol":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "Predicting Ordinal Classes in ILP")

Question: Please tell me which class the citing paper (i.e., the source paper of the center hyperedge) belongs to. The 7 classes are: Neural_Networks, Reinforcement_Learning, Probabilistic_Methods, Theory, Genetic_Algorithms, Case_Based, Rule_Learning. Directly output the class name.
