Comparison Analysis of Different Time-Scale Heart Rate Variability Signals for Mental Workload Assessment in Human-Robot Interaction

Figure 1

Framework of multiple time-scale HRV analysis for mental workload assessment. HRV: heart rate variability; ECG: electrocardiogram; SVM: support vector machine; KNN: -nearest neighbors; GB: gentle boost; LDA: linear discriminant analysis; NB: naive Bayes; DT: decision tree; TP: true positive; TN: true negative; FP: false positive; FN: false negative.
