Inline graphic — Parametric noise alters model output. Lateral view of VE geometry for all genes is shown in rows A–G (all outputs at t = 70 min). Each column displays output at t = 70 min evaluated with GRN . Columns 2–5 represent randomly chosen sample output when a normally distributed noise vector ε is added to the GRN parameter set (denoted θ). ε has mean of 0 and variance that scales with θ.
