Semantic Memory

This prior work shows that CAs can work as semantic memory.
It takes a long time to learn the concept, and repeated presentation of instances of the concept. (Long-term Memory)
However, once learned inputs can be categorised and can remain active. (Short-term or Working Memory)
That categorisation is done by CA ignition; the CA that is ignited is the one that represents the category of the object presented.
There is some work in structuring this semantic memory.
We've done some work with hierarchical categorisation, but there has been other work in sequences, cognitive maps etc.
Ambiguous stimuli can be resolved.
Figure/ground problems can be resolved.
This work is incomplete, but CAs form the only coherent neural basis to semantic memory.
There are lots of questions about having multiple concepts simultaneously active, but one can imagine solutions.
