class_docstr: Holographic Embeddings (HolE) scoring layer.
  
  The HolE model :cite:`nickel2016holographic` as re-defined by Hayashi et al. :cite:`HayashiS17`:
  
  .. math::
      f_{HolE}= \frac{2}{k} \, f_{ComplEx}
  
  where :math:`k` is the size of the embeddings.
code: def get_config(self):
      config = super(HolE, self).get_config()
      return config

  from .ComplEx import ComplEx
label_desc: Use image node_id 1 for calling the HolE obj's underlying member method code with example usage: obj.get_config() and returns: config
