t-SNE visualization of the distribution of raw data (Xraw, the first column) and aligned data by LEDA (Xleda, the second column). The red symbols ‘ × ’ denote the EEG trials from the target subject (16 × 5 = 80 trials), whereas the blue symbols ‘o’ stand for the EEG trials from all source subjects (80 × 15 = 1200 trials).
