- CAs alone don't solve all the problems.
- You need to have more flexible processing to deal with problems
like the red-square problem and rules (if X gives Y to Z, the Z
- There was a lot of criticism of connectionist systems in the 80s that
they couldn't deal with these problems.
- Variable binding solves these particular problems.
- In the rule constants are bound to the variables. So I gave
a book to Mel binds the variable X to I, Y to a book, and Z to Mel.
- I, book, Mel, gave and possess can all be CAs.
- In the red-square example, you bind the two items together.
- In associative memory the binding is semi-permanent.
- In variable binding, the binding is not permanent.
