human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge groups authors who co-authored the same paper.

Details of the hypergraph:
Center hyperedge (induced by source paper "Coverage and generalization in an artificial immune system"):
  Abstract: LISYS is an artificial immune system framework which is specialized for the problem of network intrusion detection. LISYS learns to detect abnormal packets by observing normal network traffic. Because LISYS sees only a partial sample of normal traffic, it must generalize from its observations in order to characterize normal behavior correctly. A variation of the r-contiguous bits matching rule is introduced, and its effect on coverage and generalization is studied. The effect of representation diversity on coverage and generalization is also explored by studying permutations in the order of bits in the representation.
