Processing of the ATR-FTIR and Raman datasets for all classes by GA-LDA.
(A) Thirty two wavenumbers selected by GA-LDA model for the ATR-FTIR dataset. (B) Graph representing the power calculation used to identify the optimum number of wavelengths to be used for SPA. (C) Scores (DF1 × DF2 × DF3) plot calculated by using the variables selected by GA-LDA from ATR-FTIR spectra obtained from prostate tissues segregated into seven categories. (D) Forty nine wavenumbers selected by GA-LDA model for the Raman spectral dataset. (E) Graph representing the power calculation used to identify the optimum number of wavelengths to be used for SPA. (F) Scores (DF1 × DF2 × DF3) plot calculated by using the variables selected by GA-LDA.
