Figure 1.
(a) Flow chart of our investigation: The outputs of a healthy and a defect (disease) network (receiving the same input vector) are compared. Depending on their difference they are assigned to a specific class: Class A, if both outputs are equal (no disease), class B, if the disease network has a lower but non-zero output (symptomatic disease), class C, if the disease network has zero output, while the healthy network has a non-zero output (lethal disease), class D, if both the healthy and the disease network have zero output. (b) Definition of node states and visual representation of the effect of a non-functional node. (c) Illustration of branching and visual representation of compensating a defect via interacting pathways. (d) Schematic representation of the full model and illustration of the layer structure.
