On Evolutionary Approximation of Sigmoid Function for HW/SW Embedded Systems
Sigmoid, Linear genetic programming, HW/SW co-design
Providing machine learning capabilities on low cost electronic devices is
a challenging goal especially in the context of the Internet of Things paradigm.
In order to deliver high performance machine intelligence on low power devices,
suitable hardware accelerators have to be introduced. In this paper, we developed
a method enabling to evolve a hardware implementation together with
a corresponding software controller for key components of smart embedded systems.
The proposed approach is based on a multi-objective design space exploration
conducted by means of extended linear genetic programming. The approach was
evaluated in the task of approximate sigmoid function design which is an
important component of hardware implementations of neural networks. During these
experiments, we automatically re-discovered some approximate sigmoid functions
known from the literature. The method was implemented as an extension of an
existing platform supporting concurrent evolution of hardware and software of
embedded systems.
