Query: Neuroevolution in Deep Neural Networks: Current Trends and Future
  Challenges   A variety of methods have been applied to the architectural configuration and
learning or training of artificial deep neural networks (DNN). These methods
play a crucial role in the success or failure of the DNN for most problems and
applications. Evolutionary Algorithms (EAs) are gaining momentum as a
computationally feasible method for the automated optimisation and training of
DNNs. Neuroevolution is a term which describes these processes of automated
configuration and training of DNNs using EAs. While many works exist in the
literature, no comprehensive surveys currently exist focusing exclusively on
the strengths and limitations of using neuroevolution approaches in DNNs.
Prolonged absence of such surveys can lead to a disjointed and fragmented field
preventing DNNs researchers potentially adopting neuroevolutionary methods in
their own research, resulting in lost opportunities for improving performance
and wider application within real-world deep learning problems. This paper
presents a comprehensive survey, discussion and evaluation of the
state-of-the-art works on using EAs for architectural configuration and
training of DNNs. Based on this survey, the paper highlights the most pertinent
current issues and challenges in neuroevolution and identifies multiple
promising future research directions.
