Visualization of genes associated with the Alzheimer's disease pathway. Three-dimensional representations of 50 genes, which were obtained from NMF (k = 3) using an initial matrix H built from known genes associated with the Alzheimer's disease pathway. The j-th gene is located at (h1j, h2j, h3j), where H ∈ ℝ3×50 = [h ij ]. (A red circle: APP; A red circle and blue diamonds: genes associated with the Alzheimer's disease pathway; Black dots: other genes)
