Abstract:
The presentation argues for the need to explore not just one architecture but the space of architectures (designs) and the space of requirements (niches) and trajectories in those spaces, roughly on the grounds that you can't understand a complex system without analysing what difference it would have made had it been different in various ways. That includes looking at alternative designs, at least in some neighbourhood in design space and a related neighbourhood in niche space. (I contrast numerical evaluation functions with structured descriptions of relations between design and niche). In addition, evolutionary history may give clues when we are studying, and trying to emulate, a natural architecture.

The slides include an abbreviated discussion of virtual machines and how events and processes in those machines can be causes. That is discussed more fully in the notes for the philosophy of AI tutorial by Matthias Scheutz and myself at IJCAI01: http://www.cs.bham.ac.uk/~axs/ijcai01

The slides end with a (partial) list of things we don't know.

Comments, suggestions, criticisms welcome.

DOWNLOADABLE VIEWERS

Browsers for the presentations are freely available on the internet. See the information in this file http://www.cs.bham.ac.uk/~axs/browsers.html

The diagrams in the slides were all produced using the excellent (small, fast, versatile, portable, reliable, and free) tgif package, available for linux and unix systems from here:

http://bourbon.cs.umd.edu:8001/tgif/

The slides use a format suited to fill a typical computer screen which is wider than it is tall. These need to be viewed in "Landscape" or "Seascape" mode (rotated 90 degrees to the left). Your browser should provide such an option if it does not automatically get the orientation right.
