Understanding
Intelligence
Rolf Pfeifer, Christian Scheier
Most
artificial intelligence seems artificially dumb. Sure,
Deep Blue can beat a chess grandmaster two games out of
three, but could it get out of the way of an oncoming bus?
AI researchers are coming to understand that if we want
more than idiot savants, we'll need to build our machines
from the ground up--a behaviour-based approach. Rolf Pfeifer,
Head of the Artificial Intelligence Laboratory at the University
of Zurich and Christian Scheier, Postdoctoral Fellow at
the University of Zurich and Caltech, have put together
Understanding Intelligence, the definitive introduction
to this approach for students, amateurs and professionals
alike. As they admit, there are plenty of gaps in our knowledge,
so they take pains to make our ignorance as well as our
knowledge explicit and encourage thinking beyond the text
with "Issues to Think About" at the end of each
chapter.
Delving into neural networks, subsumption architecture,
principles and design of intelligent systems, and future
applications, the authors strive to exhaust the literature
and compress it into concise, readable text with plenty
of illustrations where appropriate. Given the freshness
of the material, it feels less like a textbook and more
like a treasure map--we don't know what we'll find when
we get there but we know it's going to be good. Whether
robotics is a career, a hobby or a side interest for you,
Understanding Intelligence will help you get to work from
the bottom up. --Rob Lightner, amazon.com --This text refers
to the Hardback edition.
Synopsis
Evolutionary theory says that the brain has evolved not
to do mathematical proofs but to control behaviour and ensure
survival. Researchers agree that intelligence always manifests
itself in behaviour - thus it is behaviour that must be
understood. A new field has grown around the study of behaviour-based
intelligence, also known as embodied cognitive science,
"new AI" and "behaviour-based AI". This
book provides a systematic introduction to this new way
of thinking. After discussing concepts and approaches such
as subsumption architecture, Braitenberg vehicles,
evolutionary robotics, artificial life, self-organization
and learning, the authors derive a set of principles and
a framework for the study of naturally and artificially
intelligent systems, or autonomous agents. This framework
is based on a synthetic methodology whose goal is understanding
by designing and building. The text includes the background
material required to understand the principles underlying
intelligence, as well as information of intelligent robotics
and simulated agents so readers can begin experiments and
projects on their own. The reader is guided through a series
of case studies that illustrate the design principles of
embodied cognitive science

Artificial
Minds
Stan Franklin
Synopsis
Recent decades have produced much research in artificial
systems that exhibit important properties of mind. But what
exactly is this dramatic new work and how does it change
the way we think about the mind, or even about who or what
has mind? Stan Franklin guides the reader through the contemporary
interdisciplinary matrix of artificial intelligence, cognitive
science, cognitive neuroscience, artificial neural networks,
artificial life, and robotics that is producing a new paradigm
of mind. Along the way, Franklin makes the case of a perspective
that rejects a rigid distinction between mind and non-mind
in favour of a continuum from less to more mind, and for
the role of mind as a control structure with the essential
task of choosing the next action. Selected stops include
the best of the work in these different fields, with the
key concepts and results explained in just enough detail
to allow readers to decide for themselves why the work is
significant. The book includes animal minds, Allan Newell's
SOAR, the three Artificial Intelligence debates, John Holland's
genetic algorithms, Wilson's Animat, Brooks' subsumption
architecture, Jackson's pandemonium theory, Ornstein's multimind,
Marvin Minsky's society of mind, Patti Maes's behaviour
networks, Gerald Edelman's neural Darwinism, Drescher's
schema mechanisms, Pentti Kanerva's sparse distributed memory,
Douglas Hofstadter and Melanie Mitchell's Copycat, and Agre
and Chapman's deictic representations

Virtual
Organisms: the Startling World of Artificial Intelligence
Mark Ward
Looked at one way, all that has been achieved is some glorified
computer programmes and a few robots that stagger around even
when you blow one of their legs off. Looked at in another,
we stand on the brink of a something that has not happened
since the Earth cooled and ceased to be battered constantly
by meteors--the creation of a new and unrelated form of life.
Mark Ward's report from the front takes what is called a Strong
AI position--he dismisses as obscurantism the arguments of
philosophers that mechanical creations can never rightly be
called alive or conscious. In order to do this, he takes us
fluently through the establishment of life on earth and the
arguments of those who see it as a constant process of adaptive
symbiosis, of partnerships between specialised creatures that
together become something else. His cogent argument is essentially
that the various sorts of research into machine intelligence,
machine perception and computer programmes that imitate reproduction
and evolution will come together and produce something like
life, and will also help us understand our own evolutionary
history. This controversial position may be wishful thinking,
but if it proves not to be, Ward has laid the groundwork for
ways of coping. --Roz Kaveney
Synopsis
British Telecom are teaching small packets of software to
have sex. Telephone traffic is now so huge that it cannot
be run by a single large program, so BT are experimenting
with various species of small "ant" programs which
are autonomous and can breed and evolve better offspring by
trial, error, and natural selection. The most efficient number
of sexes is three, they have discovered. Meanwhile harmless
artificial life forms are already loose on the Internet

Cambrian
Intelligence
Rodney A. Brooks
Will we build intelligent robots from the brain down or from
the legs up? Rodney A. Brooks, controversial director of MIT's
Artificial Intelligence Laboratory, is betting on the latter--and
the smart money's following him. Cambrian Intelligence, comprised
of eight papers written between 1985 and 1991, explores the
technical and philosophical aspects of behaviour-based robotics
and offers much for the interested mind to ponder. Does cognition
mediate between perception and action, or is this an illusion?
Can a robot be called "intelligent" if it lacks
anything we would call a brain? Brooks, simply by asking these
questions, launched a new movement in artificial intelligence
and these brash, bold papers show how he laid the work for
his eventual conquest of Mars with tiny autonomous robots.
Whether you're new to Brooks, know him from his work or saw
him in the documentary Fast, Cheap and Out of Control, you'll
find much to love in Cambrian Intelligence. The four technical
papers do inspire moments of anxiety in non-technical readers
but the four philosophical papers are splendidly thought-provoking
and even a bit confrontational. (Reviewers have called his
work "inflammatory" but Brooks earns this privilege
because he's right.) While the work reported here is several
years old, it still feels fresh and new to those of us who
grew up reading about top-down artificial intelligence as
if it were the only and obvious design choice. The next generation
of intelligent robots are growing from the bottom up and you
can get in on the ground floor with Cambrian Intelligence.
--Rob Lightner
Synopsis
Presents Rodney Brooks's initial formulation of and contributions
to the development of the behavioural approach to robotics.
The text shows the philosophical/technical ideas that put
the "bottom-up" approach in the forefront of research
in not only Artificial Intelligence but in cognitive science.

Understanding
Computers and Cognition : A New Foundation for Design
Terry Winograd, Fernando Flores
This
volume is a theoretical and practical approach to the design
of computer technology. The design and development of new
technology is situated in an implicit understanding of human
nature and work. The authors assert that the deep questions
of design are those encountered when it is recognized that
in designing tools we are designing new ways of being.
This
is an excellent text which describes an approach to using
computers to perform an enabling role within corporate enterprises
by using their ability to allow clearer understanding between
participants in the workplace. The other aspect of this
book looks at current methods of creating AI systems and
their fundamental weaknesses. Having read this as part of
my MSc. in Information Technology I have re-read it several
times and I would recommend it to all those involved in
complex system design, implementation and support. In addition
a book such as Checklands Soft Systems Methodolgy will give
a good introduction to how the systems described in Understanding
Computers and Cognition can be designed to meet the demands
of "real world" environments

The
Turing Test and the Frame Problem: AI's Mistaken Understanding
of Intelligence
Larry J. Crockett
Synopsis
Both the Turing test and the frame problem have been significant
items of discussion since the 1970s in the philosophy of artificial
intelligence (AI) and the philisophy of mind. However, there
has been little effort during that time to distill how the
frame problem bears on the Turing test. If it proves not to
be solvable, then not only will the test not be passed, but
it will call into question the assumption of classical AI
that intelligence is the manipluation of formal constituens
under the control of a program. This text explains why there
has been less progress in artificial intelligence research
than AI proponents would have believed in the mid-1970s. As
a first pass, the difficulty of the frame problem would account
for some of the lack of progress. An alternative interpretation
is that the research paradigm itself is destined to be less
productive than might have been hoped. In general termns,
the view advanced here is that the future of AI depends on
whether the frame problem eventually falls to computational
techniques. If it turns out that the frame problem is computationally
irreducible, of there is no way to solve it computationally
by means of a program operating on formally defined constituents,
then an increasing number of experts in the field will reach
the conclusion that AI embodies a fundamental misunderstanding
of intelligence. |

Understanding
Artificial Intelligence
"Scientific American", Rodney Brooks
Synopsis
More than just a Steven Spielberg film, Artificial Intelligence
(AI) is the proposition that human brains are nothing more
than machines, albeit extremely complicated ones, whose
abilities will someday be duplicated-and surpassed-by computers.
Such a goal may seem elusive now, but these essays present
the wide spectrum of knowledge already compiled in pursuit
of this dream. Essays include "Th Rise of Robots,"
estimating that by 2050, robot brains based on computers
will rival human intelligence.
