Query: Novel Suboptimal approaches for Hyperparameter Tuning of Deep Neural
  Network [under the shelf of Optical Communication]   Hyperparameter tuning is the main challenge of machine learning (ML)
algorithms. Grid search is a popular method in hyperparameter tuning of simple
ML algorithms; however, high computational complexity in complex ML algorithms
such as Deep Neural Networks (DNN) is the main barrier towards its practical
implementation. In this paper, two novel suboptimal grid search methods are
presented, which search the grid marginally and alternating. In order to
examine these methods, hyperparameter tuning is applied on two different DNN
based Optical Communication (OC) systems (Fiber OC, and Free Space Optical
(FSO) communication). The hyperparameter tuning of ML algorithms, despite its
importance is ignored in ML for OC investigations. In addition, this is the
first consideration of both FSO and Fiber OC systems in an ML for OC
investigation. Results indicate that despite greatly reducing computation load,
favorable performance could be achieved by the proposed methods. In addition,
it is shown that the alternating search method has better performance than
marginal grid search method. In sum, the proposed structures are
cost-effective, and appropriate for real-time applications.
