Fig. 5: Cough strength estimation.
From: Multi-view ultrasound for diaphragm monitoring and cough strength estimation
A t-SNE feature space using all selected features, only intercostal features, and only subcostal features. The different colors of sample points represent a stronger (red) and weaker (blue) cough strength. B Scatter plot and Bland–Altman plot showing difference between true and estimated CPF in all participants (n = 120). C RMSEs using different feature subsets across coughs in test individuals (n = 24). One-way ANOVA showed no significant main effect (p = 0.942, F2, 61 = 0.060).
