Figure 5

Relative frequency in the 18 lists of the cross-validation loop. Relative frequency of the selected probesets for ε = 1 and ε = 100 when l₁-l₂ regularization is applied to the 54613 probesets. The blue line indicates ε = 1 (minimal list). The green line indicates ε = 100 (correlation aware list). The graph shows the number of probesets selected by the algorithm for the two ε (Y-axis) at increasing frequency (X-axis). When we consider a threshold on the frequency at 50% we select 11 probesets with ε = 100 and 9 with ε = 1 (vertical red dashed line).
