Stability selection. Illustration of the stability selection frequency F(g,t,L) for a fixed target gene g. Each curve represents a TF $t\in {\mathcal{T}}_g$, and the horizontal axis represents the number L of LARS steps. F(g,t,L) is the frequency with which t is selected in the first L LARS steps to predict g, when the expression matrix is randomly perturbed by selecting only a limited number of experiments and randomly weighting each expression array. For example, the TF corresponding to the highest curve was selected 57% of the time at the first LARS step, and 81% of the time in the first two LARS steps.
