Variable Binding
- I want to start by noting that the community has made some progress.
- Variable binding is the problem of giving a variable a value
in a neural system. Jackendoff (2002) says this is a major problem
for our community.
- Jackendoff dismisses binding by synchrony, but I think that's
unfair.
- Van der Velde has had binding by active links.
- We've done binding by short-term potentiation.
- We've used long-term potentiation too, but that runs into
the stability plastiticy dilemma.
- Eliasmith has used binding via vector operations.
- To some extent, these techniques address the problem,
but the question remains how does
the brain do it?
