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: "References Linear Controller Design, Limits of Performance, "The parallel projection operators of a nonlinear feedback"
  Abstract: 13] Yang, Y., H.J. Sussmann, and E.D. Sontag, "Stabilization of linear systems with bounded controls," in Proc. Nonlinear Control Systems Design Symp., Bordeaux, June 1992 (M. Fliess, Ed.), IFAC Publications, pp. 15-20. Journal version to appear in IEEE Trans. Autom. Control .

Connected through hyperedge HE-1 (induced by source paper "On Finite Gain Stabilizability of Linear Systems Subject to Input Saturation"):
  with members:
    - "New Characterizations of Input to State Stability"
    - "Global Stabilization of Linear Discrete-Time Systems with Bounded Feedback"

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.
