Number Systems for Deep Neural Network Architectures: A Survey
Deep neural networks (DNNs) have become an enabling component for a myriad of
artificial intelligence applications. DNNs have shown sometimes superior
performance, even compared to humans, in cases such as self-driving, health
applications, etc. Because of their computational complexity, deploying DNNs in
resource-constrained devices still faces many challenges related to computing
complexity, energy efficiency, latency, and cost. To this end, several research
directions are being pursued by both academia and industry to accelerate and
efficiently implement DNNs. One important direction is determining the
appropriate data representation for the massive amount of data involved in DNN
processing. Using conventional number systems has been found to be sub-optimal
for DNNs. Alternatively, a great body of research focuses on exploring suitable
number systems. This article aims to provide a comprehensive survey and
discussion about alternative number systems for more efficient representations
of DNN data. Various number systems (conventional/unconventional) exploited for
DNNs are discussed. The impact of these number systems on the performance and
hardware design of DNNs is considered. In addition, this paper highlights the
challenges associated with each number system and various solutions that are
proposed for addressing them. The reader will be able to understand the
importance of an efficient number system for DNN, learn about the widely used
number systems for DNN, understand the trade-offs between various number
systems, and consider various design aspects that affect the impact of number
systems on DNN performance. In addition, the recent trends and related research
opportunities will be highlightedComment: 28 page
