Binary Cell Assemblies
- I'm a cell assembly (CA) guy.
- I think they're really important for understanding cognition.
- I also think they're going to be really important in making
agents in neurons that learn robustly.
- CAs represent both long term and short term memory. They're
short term memory when they're firing.
- A simple version of the CA is a binary CA. Get a set of neurons
(say 10).
- Connect them so that if they start to fire they continue to
fire indefinitely.
- If you whack in some inhibitory neurons to keep them firing
at a stable rate, it's a pretty robust programming mechanism.
The last version we used had 10 neurons per CA, with 2 being inhibitory.
They fired every 5ms.
- You can connect them up so that two turn on a third, which turns off
the first, and FSA.
- A binary CA is not a great actual CA as, for instance, they only
persist for a few seconds.
- The semantic components (e.g. hot and coke) of the associative memory
were binary CAs.
