The preprocessed dataset was used to train four supervised machine learning classifiers, support vector machine (SVM), k\u2010nearest neighbors (KNN), ensemble algorithms (EA), and linear discriminant analysis (LDA), under a stratified ten\u2010fold cross\u2010validation scheme. Comparative evaluation demonstrated that SVM achieved perfect classification accuracy (100%), outperforming LDA (96.6%), EA (90.7%), and KNN (83.3%). SVM performance was evaluated against retained PC count to assess robustness and generalizability. The area under the receiver operating characteristic curve (AUC\u2010ROC) remained above 80% with two PCs and increased to 96% when eight PCs were retained. These findings underscore the clinical translational potential of machine learning driven Raman spectroscopy, with high discriminative power and generalizability for oral cancer.<\/jats:p>","DOI":"10.1002\/jbio.70373","type":"journal-article","created":{"date-parts":[[2026,10,9]],"date-time":"2026-10-09T10:27:53Z","timestamp":1791541673000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Machine
