SIGNALMONOTONICITYA property of signal monotonicity: semi-linearityComparation:a. Linear signal functions:computation and analysis is comparatively easy;do not suppress noise.b. Nonlinear signal functions:increases a network's computational richness andfacilitates noise suppression;risks computational and analytical intractability?
