The prediction accuracies thus obtained are available in Supplementary Material V, from which we can observe that the 1st order prediction accuracies followed an increasing trend with the increasing of k when k < 5, while the accuracies descended with the increase of k when k > 5 (see Table 3 for details).
The results showed that the optimized ANN can predict the time of room air temperature descending with relative accuracy.
According to Figs. 15 and 16, both KDE and dk-NN methods fail to achieve a descending level of accuracy with distance from the model's core.
This scoring function evaluates two features: (1) robustness, by measuring the similarity between the AD profiles of two external datasets, and (2) proximity to a smooth descending AD profile (accuracy vs the AD-produced measure of prediction confidence).
CO is calculated using the Stewart–Hamilton method from thermodilution curves measured in the descending aorta, with accuracy comparable with that of pulmonary artery thermodilution [ 17- 21].
It can be observed that when the similarity scores were based on same type of fingerprint, the 1st order prediction accuracies followed an increasing trend before reaching the highest accuracy and then followed a descending trend.
However, we observed that, as one descends the hierarchical path, the prediction accuracy progressively decreases as the classification task complexity increases.
For each time, the prediction accuracies generally followed a descending trend with the increase of the order number, indicating that the candidate indications of the samples in DS(i ) were sorted quite well.
Similarly, the prediction accuracies always followed a descending trend with the increase of prediction order for each time, indicating that the method based on chemical similarities also arranged the candidate indications of the samples in DS(s ) quite well.
The basic classifiers with the best performance in each cluster were sorted in descending order according to their classification accuracy to form a set of selected classifiers.
