Fig. 4From: The challenges of modern computing and new opportunities for opticsSchematic illustration of the time-delay reservoir computer [114]. The input layer is implemented by modulating input u(n) with temporal mask to create input uin(t). τm denotes mask duration, τD denotes the duration of the delay in the feedback loop, δτ denotes the temporal separation or distance of virtual nodes. The reservoir state is detected during one delayBack to article page
