Figure 8

Examples of gene-gene plots for genes X and Y are shown for characteristic tuples (MI(X,Y), R(X,Y)) detected in Figure (7). For the first gene expression dataset under consideration [31], no non-linear correlations are detected. Moreover, tuples with high Pearson correlation and low mutual information, examples A and B, resulting from outlying values are detected. For the second dataset [33], however, tuples with low Pearson correlation and high mutual information are observed, see examples C and D. Such non-linear correlations are missed by solely using linear correlation measures.
