Query: Silicon Photonic Microring Based Chip-Scale Accelerator for Delayed
  Feedback Reservoir Computing   To perform temporal and sequential machine learning tasks, the use of
conventional Recurrent Neural Networks (RNNs) has been dwindling due to the
training complexities of RNNs. To this end, accelerators for delayed feedback
reservoir computing (DFRC) have attracted attention in lieu of RNNs, due to
their simple hardware implementations. A typical implementation of a DFRC
accelerator consists of a delay loop and a single nonlinear neuron, together
acting as multiple virtual nodes for computing. In prior work, photonic DFRC
accelerators have shown an undisputed advantage of fast computation over their
electronic counterparts. In this paper, we propose a more energy-efficient
chip-scale DFRC accelerator that employs a silicon photonic microring (MR)
based nonlinear neuron along with on-chip photonic waveguides-based delayed
feedback loop. Our evaluations show that, compared to a well-known photonic
DFRC accelerator from prior work, our proposed MR-based DFRC accelerator
achieves 35% and 98.7% lower normalized root mean square error (NRMSE),
respectively, for the prediction tasks of NARMA10 and Santa Fe time series. In
addition, our MR-based DFRC accelerator achieves 58.8% lower symbol error rate
(SER) for the Non-Linear Channel Equalization task. Moreover, our MR-based DFRC
accelerator has 98% and 93% faster training time, respectively, compared to an
electronic and a photonic DFRC accelerators from prior work.
