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: "Characterizing Carbon Dynamics in a Northern Forest Using SIR-C/X-SAR Imagery Characterizing Carbon Dynamics in a"
  Abstract: 1 ABSTRACT

Connected through hyperedge HE-1 (induced by source paper "Regional Stability of an ERS/JERS-1 Classifer"):
  with members:
    (none)

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: Neural_Networks
