Fig. 15.7. Self-organization of LISSOM and GLISSOM orientation maps. The GLISSOM map is gradually scaled so that by the final iteration it has the same size as LISSOM. To make the scaling steps more obvious, this example is based on the smallest acceptable initial network; Figure 15.9 shows that results match even more closely for larger initial networks. At each iteration, the features that emerge in the GLISSOM map are similar to those of LISSOM except for discretization differences. An animated demo of these self-organization examples can be seen at ...
