САЖЕТАК / ABSTRACT:

Herein we present the potential of four machine learning (ML) algorithms: Partial Least Squares – Discriminant Analysis (PLS-DA), Random Forests (RF), Support Vector Machines (SVM) and Decision Trees (DT) to classify human plasma samples into cancer or control group, using a lipidomic dataset retrieved from the research article „Lipidomic profiling of human serum enables detection of pancreatic cancer“ by Wolrab et al. [1]. Our main objective was to assess and compare, for the four ML techniques, the performance metrics, that is accuracy, precision, sensitivity, F1 score and ROC-AUC, with those computed by Orthogonal Projections to Latent Structures (OPLS)-DA in [1]. Our findings suggest that SVM and RF offer a superior performance as binary classifiers, making these two promising candidates for future use in the discovery of potential lipidomic biomarkers.
