Figure 5. Solution is highly specific to the given reference location.

Figure 5

After assigning weights as linear function of normalized offset at the origin x0=0, the explained variance between the fixed weights and the normalized offsets relative to other locations x are calculated in A,D, 1-d, and B,E, 2-d. C,F, same as in B, and E, but for a larger area (10×10m). For a small number of grid cell inputs (N= 10), high values of the explained variance occurs throughout the environment (AC). For larger networks (N= 100), high explained variance occurs only near the reference point, i.e., the solution is specific to the reference point (D–F).
