human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "measuring information leakage in website fingerprinting attacks"):
  Abstract: Tor is a low-latency anonymity system intended to provide low-latency anonymous and uncensored network access against a local or network adversary. Because of the design choice to minimize traffic overhead (and increase the pool of potential users) Tor allows some information about the client's connections to leak in the form of packet timing. Attacks that use (features extracted from) this information to infer the website a user visits are referred to as Website Fingerprinting (WF) attacks. We develop a methodology and tools to directly measure the amount of information about a website leaked by a given set of features. We apply this tool to a comprehensive set of features extracted from a large set of websites and WF defense mechanisms, allowing us to make more fine-grained observations about WF attack and defense mechanisms.

  Member "comparing bayesian network classifiers":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "a review of visual trackers and analysis of its application to mobile robot")
