Fig. 8From: Lying position classification based on ECG waveform and random forest during sleep in healthy peopleThe comparison of the classification performance between RF, SVM and ANN. We can see that RM and ANN perform better than SVM, and the accuracies of RF and ANN are close. The Cohen’ k of ANN is slightly higher than RF. However, the calculation of RF is much faster. Consequently, RF performs best in generalBack to article page
