Abstract

Despite being originally inspired by the central nervous system, artificial neural networks have diverged from their biological archetypes as they have been remodeled to fit, particular tasks. In this paper, we review several possibilites to reverse map these architectures to biologically more realistic spiking networks with the aim of emulating them on fast, low-power neuromorphic hardware. Since many of these devices employ analog components, which cannot, be perfectly controlled, finding ways to compensate for the resulting effects represents a key challenge. Here, we discuss three different, strategies to address this problem: the addition of auxiliary network components for stabilizing activity, the utilization of inherently robust, architectures and a training method for hardware-emulated networks that, functions without, perfect, knowledge of the system's dynamics and parameters. For all three scenarios, we corroborate our theoretical considerations with experimental results on accelerated analog neuromorphic platforms.
