Fig. 3From: Tensor decomposition-based and principal-component-analysis-based unsupervised feature extraction applied to the gene expression and methylation profiles in the brains of social insects with multiple castesThe results of PCA performed on methylation profiles. PCA-based unsupervised FE was tested on methylation profiles. a and b: P. canadensis. c and d: D. quadriceps. a and c: A boxplot of PC loadings v1, (b) and (d): A PC score histogram, u1.
