Average pairwise difference between dictionary coefficients from each AR from different Mount Wilson types as measured by the Hellinger distance. Results are reported in the form of mean ± standard deviation. The size of the dictionaries is r = 6 and 8 for SVD and NMF, respectively. The βγ ARs are most dissimilar to each other and the other classes while the β ARs are most similar.
