class_docstr: An implementation of `"BigClam" <http://infolab.stanford.edu/~crucis/pubs/paper-nmfagm.pdf>`_
  from the WSDM '13 paper "Overlapping Community Detection at Scale: A Non-negative Matrix
  Factorization Approach". The procedure uses gradient ascent to create an embedding which is
  used for deciding the node-cluster affiliations.
  
  Args:
      dimensions (int): Number of embedding dimensions. Default 8.
      iterations (int): Number of training iterations. Default 50.
      learning_rate (float): Gradient ascent learning rate. Default is 0.005.
      seed (int): Random seed value. Default is 42.
