Evaluation of the FA algorithms on E. coli simulated networks. Mean squared errors (MSEs) for Λ, the varimax rotated Λ
, and the procrustes rotated Λ
are shown. The first column (a) shows the MSEs of Λ versus the network density, the second column (b) shows the MSEs of Λ versus the dataset size, and the third column (c) shows the MSEs of Λ for different values of the snr. These tests are for networks consisting of 50 genes and 8 TFs. Shown are the mean for 3 different networks. For the definition of the symbols M, Z, U, F, W and Ws see page 6.
