FIGURE 4.

Representation of the signal augmentation process. Two samples x _i and x _j are linearly combined with $\lambda \sim \mathcal{B}(\alpha ,\beta )$ . The label of x _i is adopted, given that λ >0.5. In the right, marked with a cross, the approximated location of the augmented sample. LCC: left coronary cusp; RCC: right coronary cusp; RFW: right free wall; AMC: aortomitral continuity; RVOT: right outflow tract.
