Comparison of linear ICA (NMLE) with the Plaid models, on the yeast stress spotted array dataset (dataset 3). For each GO and KEGG functional category, the largest -log10(p value) within clusters from one method is plotted against the corresponding value from the other method. (a) Gene clusters based on the NMLE components are compared with those based on the Plaid model when C for the Plaid model is fixed to its optimal value 32.5. (b) Gene clusters based on the linear ICA components are compared with those based on the Plaid model with different values of C.
