t-SNE plots [43] of randomly selected spectral pixels from absorptive (red), goblet (yellow), and stromal (green) classes show high intra-class variance (large clusters for each class) and low inter-class variance (high inter-cluster overlap) in (a) the raw spectral pixel space and (b) the NMF feature space while (c) SSNMF features show some separation of classes.
