Parsimony, Exhaustivity and Balanced Detection in Neocortex
Fig 4
Discrimination levels of PD and orthogonal architectures.
(A): Given two stimuli, activity maps are computed. The discrimination level ∥ΔA∥2 is given by the norm of the difference between the two maps (pixels with a difference smaller than 1% are not considered in the evaluation of the norm). (B) Median value (± mad) of ∥ΔA∥2 as a function of the distance δ between the presented stimuli in the parameter space for the dipolar (red) and orthogonal (blue) architectures. (C) Distribution of the difference between the median values (taken over stimuli) of the discrimination levels of dipolar and orthogonal architectures.
