Linear Fisher information after quadratic nonlinearity, unstructured weights. In contrast to Figure 4, panels a and b are plotted on a log scale. (a) Linear Fisher information as a function of the mean, , of the log-normal distribution used to draw the common noise synaptic weights. Solid lines denote means, while shaded regions denote one standard deviation across the 1000 drawings of weights from the log-normal distribution. (b) Same as panel a but for networks in which private variability dominates (, ). (c) Normalized linear Fisher information. Same plot as Figure 4c, but the average Fisher information across the 1000 samples is normalized across (akin to normalizing across ).
