A Probabilistic Palimpsest Model of Visual Short-term Memory
Figure 12
Memory curve fit for hierarchical population code.
Model fit (green; the penumbra represents one standard deviation) to the human experimental data (blue; data from [7]). These qualitative fits are similar to those obtained for a mixed population code (see Fig. 6), despite the significantly different implementation. (M = 200, ratio = 0.9, σx = 0.3). Inset: fit for [1]. Notice the difference in performance for large number of items. (M = 200, ratio = 0.9, σx = 0.55)
