SPECTRAL PEAK VERIFICATION AND RECOGNITION USING A MULTILAYERED NEURAL NETWORK

The verification and recognition of peak-shaped signals in analytical data are ubiquitous scientific problems. Experimental data contain overlapping signals and noise, which make sensitive and reliable peak recognition difficult. A peak detection system based on a class of neural networks known as “multilayered perceptions” has been created. The network was trained and evaluated with use of vapor-phase infrared spectral data. The results of varying the network architecture on system training and prediction performance along with refinement of the form of the input pattern are presented. © 1990 American Chemical Society.
