From: Independent component analysis of Alzheimer's DNA microarray gene expression data
The first 10 PCs and ICs extracted by PCA and ICA methods respectively. (A) The first 10 PCs obtained by PCA that capture 95.5% information of original AD microarray data. (B) The first 10 ICs (gene signatures) uncovered by ICA from AD microarray data in which only a few relevant genes were significantly affected, leaving the majority of genes unaffected. The x-axis in each graph denotes genes, and the y-axis represents relative signal intensity.
