Deep spectral CNN for laser induced breakdown spectroscopy [PDF]

Spectrochimica Acta Part B: Atomic Spectroscopy, 2021
This work proposes a spectral convolutional neural network (CNN) operating on laser induced breakdown spectroscopy (LIBS) signals to learn to (1) disentangle spectral signals from the sources of sensor uncertainty (i.e., pre-process) and (2) get qualitative and quantitative measures of chemical content of a sample given a spectral signal (i.e ...
