Optical neuromorphic computing via temporal up-sampling and trainable encoding on a telecom device platform. [PDF]
NanophotonicsAbstract Mapping input signals to a high‐dimensional space is a critical concept in various neuromorphic computing paradigms, including models such as reservoir computing (RC) and extreme learning machines (ELM). We propose using commercially available telecom devices and technologies developed for high‐speed optical data transmission to implement ...
