Abstract(in Japanese) (See Japanese page)
Abstract(in English) Echo state Network (ESN), a class of recurrent neural network, is characteristic in its use of a reservoir having random and constant weights during training and inference computations. ESN is suitable for hardware implementation because of its low training cost and simple neural architecture. Recently, MOS-ESN is proposed to implement ESN by using hardware reservoir consists of physical metal-oxide-semiconductor field effect transistors (MOSFETs). The variations in MOSFETs are used as the source of the random weights without the need to manually tune the parameters for stability. MOS-ESN and the related Dual-MOS-ESN architecture demonstrates high inference accuracy on a particular dataset, but the evaluation is inadequate. In this paper, we conduct a more thorough performance evaluation for Dual-MOS-ESN and other similar hardware reservoir structures. Through the evaluation, we show the effectiveness of the dual architecture across datasets in comparison with other MOS-ESN architectures.
