ICA decomposition results of AD microarray gene expression data. FastICA was applied to the AD microarray data matrix X with 13 samples and 3617 genes. Using the ICA method, X = AS, FastICA algorithm decomposes matrix X (13 × 3617) into latent variable matrix A (13 × 13) and gene signature matrix S (13 × 3617).
