a Latent space embeddings of the Recurrence plot and b latent space RQA features, are presented in Fig. 2a, b, respectively. The corresponding t-SNE visualizations on the test data are shown in Fig. 2c, d. These figures demonstrate the inter-class separability among different CVDs and HC achieved by the proposed method.
