    Snippet: Support Vector Machines (SVM) 12 is an AI technique used for binary classification (i.e. a given sample is classified as "positive" or "negative"). SVM has been successfully used in many biomedical applications 8, 16 . However, due to the small number of "positive" samples in the dataset (13.52%), the technique is prone to favor the majority class predicting all samples as "negative" and leading to extremely low sensitivity.

    Document: Support Vector Machines (SVM) 12 is an AI technique used for binary classification (i.e. a given sample is classified as "positive" or "negative"). SVM has been successfully used in many biomedical applications 8, 16 . However, due to the small number of "positive" samples in the dataset (13.52%), the technique is prone to favor the majority class predicting all samples as "negative" and leading to extremely low sensitivity. To overcome such imbalance in classes, oversampling and ensemble methods were applied.
