Table 1 Nomenclature for spatial metrics
From: Hippocampus supports multi-task reinforcement learning under partial observability
Symbol | Meaning |
|---|---|
i | Index over spatial bins |
pi | Occupancy probability of bin i |
ri | Mean activity (firing rate) in bin i |
\(\bar{r}\) | Overall mean activity, \(\bar{r}={\sum }_{i}{p}_{i}\,{r}_{i}\) |
\({\tilde{r}}_{i}\) | Local mean activity (3 × 3 uniform filter) |
ϵ | Small constant (10−8) to avoid division by 0 |
