Comparison of the MSD method to the baseline classifier. The performance of 1NN with DTW using different time series length and MSD on the viral infection datasets. The left (right) group shows accuracy of the classifiers on H3N2 (HRV) dataset, respectively. The x-axis within a group is ordered by the fraction of the time series, shown in parenthesis. The results provide evidence that the MSD method is more accurate than 1NN.
