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 "Utilizing Connectionist Learning Procedures in Symbolic Case Retrieval Nets"):
  Abstract: This paper describes a method which, under certain circumstances, allows to automatically learn or adjust similarity measures. For this, ideas of connectionist learning procedures, in particular those related to Hebbian learning, are combined with a Case-Based Reasoning engine.

Includes members:
  Member "Case Retrieval Nets: Basic Ideas and Extensions":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "Preparing Case Retrieval Nets for Distributed Processing")

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.

gpt: Case_Based
