Comparative Analysis of LDA, PLS-DA, SVM, RF, and Voting Ensemble for Discrimination Origin in Greenish-white to White Nephrites using LIBS As there are distinct variations in economic value for greenish-white to white nephrites based on their geographical origin, it is crucial to develop a robust origin discrimination method for them. The reported correlation between the intensity of spectra and material properties gives us a clue that such a correlation may exist in nephrites worldwide.
