Architecture: from the Latin -teks - To weave
(as a net); also to fabricate, a root shared with text, textile,
context, subtle ("the finest thread of the weave") and technology.
More especially, to build a dwelling, with tools."
American Heritage Dictionary
An architecture, portion of a system that provides and manages
the primitive resources of an agent. For a cognitive architecture,
these resources define the substrate upon which a physical symbol
system is realized. The many issues surrounding the choice, definition,
extent, and limits of these resources and their management is one
of the purposes of this document. This analysis attempts to assist
in determining the necessary, sufficient and optimal distribution
of resources to the development of agents exhibiting general intelligence.
Architectures, in general, have divergent features
that lead to different properties. For example, some utilize a uniform
knowledge representation, some a heterogeneous representation, and
others, no explicit representation at all. These decisions then
lead to the support of specific capabilities. The choice of features
is often made by following some explicit methodological assumptions,
often driven by the domains and environments in which the architecture
will be used. The variety of these choices are what is responsible
for the variety of architectures. One way to further constrain the
number of choices is to use examples of psychological or neuroscientific
validity in architecture design. An additional advantage of this
approach is that there is synergistic interchange between the studies
of artificial and biological intelligence; in particular, Newell
has proposed that computer modeling tools as represented by cognitive
architectures now allow the formulation of unified theories of cognition.
Indian
techniques of art and architecture spread both westwards and
eastwards. During the reign of Ashoka; Afghanistan, Baluchistan
and Seistan were parts of the Mauryan empire. Buddhist Stupas were
constructed in these Mauryan provinces. Unfortunately, very few
of them have survived till today.
