From: Riemannian geometry-based transfer learning for reducing training time in c-VEP BCIs

Classification accuracies of two target subjects (#5 and #7) yielded by the two transfer learning algorithms TL (a,b) and TL-LEDA (c,d) with the EEG trials of only one source subject transferred to the target subject. The sold line in each subplot stands for the accuracy yielded by SSL (baseline) algorithm.
