Figure 4-1
Simulation results showing the impact of different types of spatial subsampling. In all cases, we simulated a system of 15,000 neurons before temporally subsampling by a factor of 15 and spatially subsampling to 250 neurons. Each subplot then shows the impact of further subsampling from this initial population of 250 neurons. A–H, Left column (A, C, E, G), Temporal subsampling by skipping bins; right column (B, D, F, H), temporal summation by summing over skipped bins. A–D, Spatial subsampling by binomial subsampling (i.e., skipping individual spikes). E–H, Systematic subsampling by skipping neurons. A, B, E, F, mtrue = 0.9999, m = 0.9985; C, D, G, H, mtrue = 0.985, m = 0.7972. Download Figure 4-1, TIF file.
