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 "faster population counts using avx2 instructions"):
  Abstract: Counting the number of ones in a binary stream is a common operation in database, information-retrieval, cryptographic and machine-learning applications. Most processors have dedicated instructions to count the number of ones in a word (e.g., popcnt on x64 processors). Maybe surprisingly, we show that a vectorized approach using SIMD instructions can be twice as fast as using the dedicated instructions on recent Intel processors. The benefits can be even greater for applications such as similarity measures (e.g., the Jaccard index) that require additional Boolean operations. Our approach has been adopted by LLVM: it is used by its popular C compiler (Clang).

Includes members:
  Member "consistently faster and smaller compressed bitmaps with roaring":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "techniques for inverted index compression")
  Member "simd compression and the intersection of sorted integers":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "permute to train a new dimension to training deep neural networks")
  Member "better bitmap performance with roaring bitmaps":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "a computational model for analytic column stores")
