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 "approximation capabilities of neural networks on unbounded domains"):
  Abstract: If $p \in (1, \infty)$ and if the activation function belongs to a monotone sigmoid, relu, elu, softplus or leaky relu, we prove that neural networks are universal approximators of $L^{p}(\mathbb{R} \times [0, 1]^n)$. This generalizes corresponding universal approximation theorems on $[0,1]^n.$ Moreover if $p \in (1, \infty)$ and if the activation function belongs to a sigmoid, relu, elu, softplus or leaky relu, we show that neural networks never represents non-zero functions in $L^{p}(\mathbb{R} \times \mathbb{R}^+)$ and $L^{p}(\mathbb{R}^2)$.

Includes members:
  Member "understanding deep neural networks with rectified linear units":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "lossless compression of deep neural networks")
  Member "fast and accurate deep network learning by exponential linear units elus":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "ride rewarding impact driven exploration for procedurally generated environments")
