A Simple Model of Optimal Population Coding for Sensory Systems
Figure 5
The reconstruction error as a function of neural population size.
Two x-axes represent, respectively, the cone: RGC ratio (top) and the corresponding retinal eccentricity in the macaque retina (bottom; see Figure 2). The problem settings are the same as in Figure 4 with extended cell ratios; the common cell ratios (1∶1 and 16∶1) are indicated by the same labels (open and closed triangles, respectively). The signal dimension is 121×121 = 14,641 for all condition; the number of neurons with 16∶1 cell ratio is 915.
