Here, RB1 denotes the first residual block, RB3 denotes the third residual block, RB4 denotes the fourth residual block, and UB denotes the up-sampling block. t-SNE, UMAP and MDA results are shown in (a–c) respectively for training and testing datasets at different network layers. The colorbar denotes the normalized manifold distance. d Pearson correlations between the geodesic distances among feature data points in HD and low dimensional representation from different methods are shown for training and testing data. Source data are provided as a Source Data file.
