From: Riemannian geometry-based transfer learning for reducing training time in c-VEP BCIs
Processing flowchart of the Riemannian geometry-based transfer learning in c-VEP BCIs. The meanings of the acronyms in the figure are as follows. LOO: leave-one subject-out; SSs: source subjects; TS: target subject; LE(DA): log-Euclidean (data alignment); SCMs: sample covariance matrices; TSS: training accuracy-based subject selection; MDM: minimum distance to mean.
