human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent groups of papers sharing a common citing paper.

Details of the hypergraph:
Center node: "The Design and Evaluation of a Rule Induction Algorithm"
  Abstract: technical report BYU-CS-93-11 June 1993

Connected through hyperedge HE-1 (induced by source paper "NP-Completeness of Minimum Rule Sets"):
  with members:
    - "The Minimum Feature Set Problem"

Question: Please tell me which class the center node 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: Theory
