On-chip non-volatile all-optical residual neural network accelerator
The NARCA-based architecture outperforms the conventional optical convolution architecture across different neural-network tasks and greatly improves the residual convolution operation speed compared with the electrical architecture, with a relative root mean square error of less than 0.125.
