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: "Some Varieties of Qualitative Probability"

Connected through hyperedge HE-1 (induced by source paper "Explaining "Explaining Away""):
  with members:
    - "Inference in Cognitive Maps"

Connected through hyperedge HE-2 (induced by source paper "Incremental Tradeoff Resolution in Qualitative Probabilistic Networks"):
  with members:
    - "Exploiting Causal Independence in Bayesian Network Inference"
    - "Using Qualitative Relationships for Bounding Probability Distributions"
    - "State-Space Abstraction for Anytime Evaluation of Probabilistic Networks"

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.
