Abstract
The energy detection model in the preceding chapter can easily be modified to incorporate topography, i.e. an arrangement of the features on a two-dimensional grid. This is very interesting because such organization is one of the most prominent phenomena found in the primary visual cortex. In this chapter, we shall investigate such a topographic version of the ICA model. It is, mathematically, a rather simple modification of the independent subspace analysis model.
