Categorical matrix factorization as an alternative representation of DFA in Figure 2. ${\mathit{D}}^{-}={\mathit{D}}^{°}I(\mathit{C}=-1)$ and ${\mathit{D}}^{+}={\mathit{D}}^{°}I(\mathit{C}=+1)$. Diseases correspond to the columns of $\mathit{A}$ and the rows of ${\mathit{D}}^{-}$ and ${\mathit{D}}^{+}$. They are represented by the same set of colors as in Figure 2.
