Figure 7. EMD robustness to intensity changes.

Incremental field scaling (increasing intensity) across a (17,17) ratemap with a field at the center (A). Field is scaled from = 1 to $\sigma =6$ (left). Intensity changes are considered using whole map EMD (red), field restricted EMD (green) and a binary EMD (blue) using raw spike positions. Normalized (top right panel) and unnormalized (bottom right panel) weights are shown for both. EMD scores tested against different firing rate ratios for two identical fields (B). Ratios greater than 1 and less than 1 were tested.
