PCA visualization of the classification output data distribution for different ablation variants of the proposed MSDS-FusionNet on an example subject in the NinaPro DB2 dataset. Each subplot shows the 3D PCA projection of the network’s final layer output with a Davies-Bouldin Index (DBI) score, illustrating the separability of different classes.
