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 "Exemplar-based Music Structure Recognition"):
  Abstract: We tend to think of what we really know as what we can talk about, and disparage knowledge that we can't verbalize. [Dowling 1989, p. 252]

Includes members:
  Member "A Weighted Nearest Neighbor Algorithm for Learning with Symbolic Features":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "Towards a Better Understanding of Memory-Based Reasoning Systems")

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
