Abstract

Deep neural networks (DNN) have been successfully used in diverse emerging domains to solve real world complex problems with may more deep learning (DL) architectures, being developed to date. To achieve this state-of-the-art (SOTA) performances, the DL architectures use activation functions (AFs), to perform diverse computations between the hidden layers and the output layers of any given DL architecture. This paper presents a survey on the existing
AFs used in deep learning applications and highlights the recent trends in the use of the AFs for DL applications. The novelty of this paper is that it compiles the majority of the AFs used in DL and outlines the current trends in the
applications and usage of these functions in practical deep learning deployments against the SOTA research results. This compilation will aid in making effective decisions in the choice of the most suitable and appropriate AF for a given
application, ready for deployment. This paper is timely because majority of the research papers on AF highlights similar works and results while this paper will be the first, to compile the trends in AF applications in practice against the
research results from the literature, found in DL research to date.
