The paper comments on the article by X. Zheng et al. on combining derivative Raman with autofluorescence to improve the diagnosis performance of echinococcosis. Despite the high performance of the proposed approach, the results may be ambiguous due to the incorrect number of principal components utilized in classification models for spectral datasets analysis.
This paper comments on the article Combining derivative Raman with autofluorescence to improve the diagnosis performance of echinococcosis by X. Zheng et al. The authors put forward an idea to apply Raman spectroscopy and autofluorescence to measure spectral characteristics of human serum and diagnose echinococcosis. Despite the high performance of the proposed approach, the demonstrated results may be ambiguous due to the incorrect number of the utilized principal components in classification models for spectral datasets analysis.
