Two-valued Logic
Many of the architectures analyzed build upon a substrate of two-valued
logic. This effectively precludes the capability of discerning shades
of meaning,
although several authors claim that such a mechanism could be layered in
or added in a case-specific way. To add the capability, one would add
huge memory and computational requirements, byte-for-byte, compared to
an architecture which inherently deals with continuous variables. Note that
to perform operations on continuous variables, more primitive operations
are needed beyond logical operators.
The following architectures are built on two-valued logic:
The following architectures explicitly utilize continuous variables:
