The Performance of Short-Term Heart Rate Variability in the Detection of Congestive Heart Failure
Table 1
Classification results. KNN (-nearest-neighbor) with and without MinMax normalization. KNN/GA (genetic algorithm) optimization with and without MinMax normalization. The results use a 23-fold cross-validation where Ac (accuracy), Se (sensitivity), and Sp (specificity) quantify the performance assessment of the classifier using features.
