Figure 7.

Plots of experimental [18] and simulated data for the PCNA gene using the fuzzy rule set model found for the TT3 training data set. Shown here are (top) a typically reasonable fit, E = 0.249 and P = 3.47*10^-7 on the training data set, and (bottom) a typically poorer fit (for a rule found using the evolutionary algorithm), E = 0.745 and P = 1.37*10^-2 on the TN data set. The plots show the base 2 logarithm of the gene expression ratios (so the simulated results are transformed back from the normalized form) versus points in the experimental time series (arbitary units).
