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 "a note on solving nonlinear optimization problems in variable precision"):
  Abstract: This short note considers an efficient variant of the trust-region algorithm with dynamic accuracy proposed Carter (1993) and Conn, Gould and Toint (2000) as a tool for very high-performance computing, an area where it is critical to allow multi-precision computations for keeping the energy dissipation under control. Numerical experiments are presented indicating that the use of the considered method can bring substantial savings in objective function's and gradient's evaluation "energy costs" by efficiently exploiting multi-precision computations.

Includes members:
  Member "training deep neural networks with 8 bit floating point numbers":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "sparse weight activation training")
  Member "doing moore with less leapfrogging moore s law with inexactness for supercomputing":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "data driven prediction of a multi scale lorenz 96 chaotic system using deep learning methods reservoir computing ann and rnn lstm")
  Member "accelerating scientific computations with mixed precision algorithms":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "deep learning with limited numerical precision")
