Relationship between \({C_{b}^{i}}\) and features with distinct expression among four classes. Left column: histogram obtained from logarithmic \({C_{b}^{i}}\) for 100 independent ensembles. Red color indicates features with distinct expression between four classes. Right column: proportion of features with distinct expression between four classes in each bin. Top: s=2, easy; middle: s=1, medium; bottom: s=0.5, hard cases.
