PCA visualization of the classification output data distribution for the proposed MSDS-FusionNet on an example subject in the NinaPro DB2 dataset. The 3D PCA projection illustrates the separability of different classes, with distinct clusters formed for each gesture category, with a Davies-Bouldin Index (DBI) of 2.1158, indicating strong discriminative power.
