Predictions using synthetic data on HOG signaling pathway. In this figure, blue stars denote the synthetic data whereas magenta squares denote the SPCA predictions when the associated data points were left out as test set points. The red and the green solid lines show the time profiles predicted by the ODE
and the ODE
, respectively. The upper 4 subplots belong to the 0.4 M. NaCl shock experiment and the lower 4 subplots belong to the 0.5 M. NaCl shock experiment. The glycerol, Hog1 dependent protein (mainly Gpd1p) and mRNA amounts (in μ moles) are in absolute scale whereas we used the normalized phosphorylated Hog1p values. The Hog1p values were normalized to their maximum value measured in the corresponding experiment.
