A Two-Level Model for the Analysis of Syndrome of Acute Ischemic Stroke: From Diagnostic Model to Molecular Mechanism

Figure 4

The accuracies of classification schemes after pairwise undersampling. Two samples whose Euclidean distance is below the threshold are combined. The black line indicates accuracies of models after pairwise undersampling based on different distance thresholds. The red line presents the accuracy of the original classification scheme based on core symptoms without undersampling as a comparison.
