A gradient-based discriminant analysis method for process quality control of carbonized TCM via Fourier transform near infrared spectroscopy: A case study on carbonized Typhae Pollen
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy(2022)
Abstract
•A new pattern recognition strategy is developed to solve the problems of carbonized TCM.•The new proposed method gains higher accuracy than CNN, LDA and SNV-LDA.•A new algorithm is designed for near-infrared spectroscopy pre-processing and feature extraction.
