Limitations of coarse coding
It achieves accuracy at the cost of resolution
Accuracy is defined by how much a point must be
moved before the representation changes.
Resolution is defined by how close points can be and
still be distinguished in the represention.
Representations can overlap and still be decoded if we allow
integer activities of more than 1.
It makes it difficult to associate very different responses
with similar points, because their representations overlap
This is useful for generalization.
The boundary effects dominate when the fields are very
big.
