Compressive sensing (CS) spectroscopy is well known for developing a compact spectrometer which consists of two parts compressively measuring an input spectrum and recovering the spectrum using reconstruction techniques. Our goal here is to propose a novel residual convolutional neural network (ResCNN) for reconstructing the spectrum from the compressed measurements.
