Deep photonic reservoir computer for nonlinear equalization of 16-level quadrature amplitude modulation signals
Rui-Qian Li, Yi-Wei Shen, Zekun Niu +5
Photonic reservoir computer (PRC) is a kind of real-time and adaptive recurrent neural network, where only weights in the readout layer require training. PRC is a promising tool to…
