Pattern Recognition
Pattern recognition is the research area that studies the operation and design of systems
that recognize patterns in data. It encloses subdisciplines like discriminant analysis,
feature extraction, error estimation, cluster analysis (together sometimes called statistical
pattern recognition), grammatical inference and parsing (sometimes called syntactical
pattern recognition). Important application areas are image analysis, character
recognition, speech analysis, man and machine diagnostics, person identification and
industrial inspection

Actors and neighbors.
Easel's architecture is designed so that it can simulate very large numbers of independent "actors"
(analogous to the participants discussed above). Actors are simulated entities of the physical
world (e.g., a
system administrator, user, intruder, automobile, bird, or the moon), of the electronic world (e.g.,
a
computer, router, or peripheral device), or of the software world (e.g., a software agent or task).
Each actor
has it own thread of control and this allows for a high degree of parallelism in Easel's execution.
Actors can
interact directly only with their near neighbors and only in ways prescribed by their neighbor
relationships.
Neighbor relationships are protocols of interaction and are defined as types that can be associated
with any
actor. Thus, in a simulation of birds in flight, a bird's near neighbors might be any bird or other
object that
the bird can see from its current position and heading. In an organizational simulation, an actor's
near
neighbors might be only those actors that are connected by formal organizational ties. In the latter
example,
neighbor operations might include sending and receiving messages.

Neural Networks

Computers are the ideal metaphor for the human mind. Cognitive scientists have
long used the serial processor as their model for the brain because this type of
computer excels in deductive reasoning.

Researchers are also exploring whether parallel processors can serve as models
for how the brain functions. Parallel processors are computers that excel at
pattern recognition, or inductive thinking. Parallel processors that can handle
many instructions at once are called neural networks (or nets). Neural nets excel
at inductive tasks, such as pattern recognition, for which many commercial
applications are now being developed.

It's possible these researchers will conclude that the brain is not a linear tool, as
originally suggested by the serial model, but that the parallel model of processing
information more closely represents how the mind works. Maybe the ultimate
model of the human brain would be one that combines both the serial and
parallel analogies.

1.1 Artificial Intelligence and Intelligence

There are two goals to AI, the biggest one is to produce an artificial system that
is about as good as or better than a human being at dealing with the real world.
The second goal is more modest: simply produce small programs that are more
or less as good as human beings at doing small specialized tasks that require
intelligence. To many AI researchers simply doing these tasks that in human
beings require intelligence counts as Artificial Intelligence even if the program
gets its results by some means that does not show any intelligence, thus much of
AI can be regarded as "advanced programming techniques".

Golem Project

Without reference to specific organic chemistry, life is an autonomous design process
that is in control of a complex set of chemical factories allowing the generation and
testing of physical entities that exploit the properties of the medium of their own
construction. Using a different medium, namely off-the-shelf rapid manufacturing, and
evolutionary design in simulation, we have made progress towards replicating this
autonomy of design and manufacture. This is the first time any artificial evolution system
has been connected to an automatic physical construction system. All together, our
evolutionary design system, solidification process, and rapid prototyping machine form a
primitive "replicating" robot. While there are many, many further steps before this
technology is dangerous, we believe that if indeed artificial systems are to ultimately
interact and integrate with reality, they cannot remain virtual; it is crucial that they cross
the simulation-reality gap to learn, evolve and affect the physical world directly.
Eventually, the evolutionary process must accept feedback from the live performance of
its products.

Feedforward for faster control response
Control systems often rely on feedforward to improve their ability to respond to the command
signal. Feedforward is based on the structure in control systems where one loop is nested inside
another.
For example, in motion control systems, a velocity loop is often enclosed inside a position loop.
The position loop generates a velocity command, which is shuttled to the velocity loop. In this
control structure, the inner loop is always faster than the outer loop. The feedforward path is
essentially a shortcut around the slower outer loop, allowing the command signal direct access to
the faster inner loop.

http://www.controleng.com/archives/2000/ctl1001.00/0010bb.htm

Self-modeling is a process where people watch themselves performing a desired behavior or skill,
generally on videotape. It has proven to be effective in changing behavior, improving skills, and
increasing self-confidence. Video feedforward is a special type of self-modeling in which images
of future behavior, or a skill not yet acquired, are created using hidden supports and editing
techniques. ACE Reading uses video feedforward to create images of children reading
successfully, which can actually help them improve their reading skills.

http://www.cds.hawaii.edu/reading/feedforward.html

Feedforward: anticipating perturbations
Feedback and feedforward both require action on the part of the system, to suppress or
compensate the effect of the fluctuation. For example, a thermostat will counteract a drop
in temperature by switching on the heating. Feedforward control will suppress the
disturbance before it has had the chance to affect the system's essential variables. This
requires the capacity to anticipate the effect of perturbations on the system's goal.
Otherwise the system would not know which external fluctuations to consider as
perturbations, or how to effectively compensate their influence before it affects the
system. This requires that the control system be able to gather early information about
these fluctuations.
For example, feedforward control might be applied to the thermostatically
controlled room by installing a temperature sensor outside of the room, which
would warn the thermostat about a drop in the outside temperature, so that it
could start heating before this would affect the inside temperature. In many
cases, such advance warning is difficult to implement, or simply unreliable. For
example, the thermostat might start heating the room, anticipating the effect of
outside cooling, without being aware that at the same time someone in the room
switched on the oven, producing more than enough heat to offset the drop in
outside temperature. No sensor or anticipation can ever provide complete
information about the future effects of an infinite variety of possible perturbations,
and therefore feedforward control is bound to make mistakes. With a good control

system, the resulting errors may be few, but the problem is that they will
accumulate in the long run, eventually destroying the system.

Complexity

Characteristics of a complex system

A complex system is emergent. In an emergent system,
smaller parts comprise a larger system. This larger system has
properties the smaller units lack. For example, the brain is made up
of individual neurons that, when functioning together, are capable of
tasks no single neuron can perform alone. The new properties only
emerge when the neurons work together.

A complex system is unpredictable.

A complex system contains many iterations and
feedback/feedforward loops.

In a complex system, decision-making is decentralized.

Learning is a typically a "complex" activity. Most learning systems contain a
number of separate parts that must work together for learning to occur. For
example, a typical learning system consists of students, a teacher, a content
focus, and resources. This system operates according to a fixed plan--the
students follow the teacher's "rules."
Learning environments

A learning environment can be emergent. Working together,
a group of learners can collectively build their knowledge of a topic,

for instance, the phases of the moon. To do so, each learner might
research a particular lunar phase, then share what he or she has
learned with the rest of the group. This way, the group amasses a
body of knowledge that no one person could have acquired alone.

A learning environment can be unpredictable. An
exploration of the phases of the moon could result in the group
considering whether planets also have phases.

A learning environment can contain many iterations and
feedback/feedforward loops. People learn by trial and error--in
other words, they learn from their mistakes.

Decision-making in a learning environment can be
decentralized. Groups can really thrive when students control the
learning process, rather than the instructor.

What is interaction? How can we begin to make sense of the avalanche of
educational toys, computer programs, and artworks that claim to be
"interactive?" What would a new pedagogy structured around the rules of
interactivity look like?
------
Some theorists have argued that all "art is interactive," effectively shutting the
door on the discrete contributions of new digital/computer-based interactivity.
Conversely, other theorists such as Simon Penny have insisted that traditional
artworks such as painting and sculpture are simply "instances of representation"
and as such should not be defined as truly "interactive systems." For Penny,
interactive artworks are "virtual machines which...produce instances of
representation based on real time inputs." (Penny 1996) Still other theorists
distinguish between the relationship of system interactivity (the enabling

hardware and software) and the nature of the interaction (the actual exchange--
be it aesthetic, educational, political, etc.) (Hillman et al, 1994). For our
purposes here, a high level of interaction equals "mutual reciprocity"--a state of
dialectical exchange between two or more entities. Ideally, interactive
systems--whether a high tech computer game or a Socratic dialogue--can be
tools for learning providing intelligent feedback that refines and amplifies user
input.

While the demand for "interactivity" is a relatively recent phenomenon in the
arts, the culture at large has long been obsessed with the idea of machines that
learn. The evidence is mounting. From media spectacles such as Big Blue's
defeat of World Chess Champion Garry Kasporov in May of 1997 to quieter
revolutions in teaching autistic children, computers that master the behaviors of
their users are beginning to find a place in the culture. There is more than a hint
of narcissism in our desire to be personally reflected in the machines we make.
We don't want simply "dumb" tools, we want "intelligent" machines that
respond and learn by interacting with their owners. Even our cooking
appliances and car radios are "programmable" to reflect individual tastes.

Few art schools provide courses for producing let alone interpreting or
critiquing "interactive artworks." Though the borderline between the fine arts
and other cultural practices (such as science, technology, and entertainment) is
becoming increasingly blurred, it is clear that the development of "interactive
art" is largely dependent on "non-art" traditions. From a technical and
theoretical perspective, such strange bedfellows as computer gaming, combat
simulation, and medical diagnostics have more in common with much recent
digital and interactive art practice than main stream art history or criticism.
Theorizing this territory is less a matter of mining, say, the Art Index, and more
a matter of conducting systematic research into areas such as communications
theory, human computer interaction, educational technology, and cognitive
science. With this in mind, it may be helpful to briefly review how other
disciplines are looking at the issues surrounding interaction.

THEORIES OF INTERACTION

"Interaction" is a useful construct in helping to understand the complex
relationships occurring in a computerized learning environment. Educational
technologist Ellen Wagner defines interaction as "… reciprocal events that
require at least two objects and two actions. Interactions occur when these
objects and events mutually influence one another." (Wagner, 1994)

Wagner points to historical examples of communication theory to illustrate the
move from "one-way" systems of communication to "multi-directional"
systems. C.E. Shannon's mathematical theory of communication (Shannon,
1948), for example, was a highly linear engineering model of information
transfer involving the one-way transmission of information from a source to a
destination using a transmitter, a signal, and a receiver. Later theorists built
upon Shannon's model to include the concepts of interactivity and feedback. It
is only recently that truly interactive systems that support both synchronous and
a-synchronous exchanges among multiple users have been available. Common
examples of synchronous exchange include live satellite uplinks, telephones,
and chat rooms on the Net. E-mail is the prototypical example of an
"asynchronous" exchange system.

Other trends supporting the development of interactive systems come from
research in artificial intelligence and cognitive science. If "mutual influence"
and reciprocity are criteria for true interactivity, then the system needs to be
capable of delivering more than pre-existing data on demand. Interactive
systems need to be able to generate "custom" responses to input and queries. In
short, the system needs to be smart enough to produce output that is not already
part of the system. Interactivity must be more than following predetermined
prompts to preprogrammed conclusions like in a video game

While most natural and living systems are "productive" in the sense of creating
new "information," human-made machines that can respond with anything
more than simple binary "yes/no" responses are a relatively recent
phenomenon. To paraphrase media artist Jim Campbell, most machines are
simply "reactive," not interactive. "Intelligent" machines, being developed with
the aid of "neural networks" and "artificial intelligence," can interact by
learning new behaviors and changing their responses based upon user input and
environmental cues. Over time, certain properties begin to "emerge" such as
self-replication or patterns of self-organization and control. These so-called
"emergent properties" represent the antithesis of the idea that the world is
simply a collection of facts waiting for adequate representation. The ideal
system is a generative engine that is simultaneously a producer and a product.

"INTERACTIVE" ARTWORKS

Creating an experience for a participant in an interactive artwork must take into
account that interactions are, by definition, not "one-way" propositions.
Interaction depends on feedback loops that include not just the messages that
preceded them, but also the manner in which previous messages were reactive.

When a fully interactive level is reached, communication roles are
interchangeable, and information flows across and through intersecting fields of
experience that are mutually reciprocal. The level of success at attaining mutual
reciprocity could offer a standard by which to critique interactive artwork.

Many artists have developed unique attempts at true interaction, addressing
problems of visual display, user control processes, navigation actions, and
system responses. Different works have varying levels of audience
participation, different ratios of local to remote interaction, and either the
presence or absence of emergent behaviors. Moreover, different artistic
attempts at interactivity suggest different approaches to interaction could be
used for diverse kinds of learners in a variety of educational settings.
Understanding experiments with interaction in an art context may help us to
better understand interaction in pedagogical settings.

Carol Flax: Journeys: 1900/2000

Arizona artist Carol Flax has created an "interactive book" entitled,
Journeys: 1900/2000 at the Institute for Studies in the Arts at Arizona
State University, where I am the Interim Director. At the heart of the
project is a reproduction of a 19th century travel album that trades in

fragments of memory, pieces of voyages, and bits of history. It uses
single images from various existing albums, reproducing and
recontextualizing them to create a completely original "voyage."
Movement sensing technology (computerized tracking devices) sense
the presence of a viewer. "Bend sensors" embedded in the pages cause
an electrical signal to be sent to a computer when a page is turned.
Video and audio clips are in turn triggered that support, amplify, or
contest the veracity of the photographic prints of idealized ancient
settings through the simple juxtaposition of contemporary imagery and
sound with historical photographs. For example, a black and white
image of a Middle Eastern market--a classic example of the "exotic" and
the "picturesque"--is overlaid with a video closeup in color of an orange
being passed from the hand of one person to another in an Arizona
back yard. Text is used throughout both descriptively and ironically to
throw into question the truth value of what we are seeing. The message
is deliberately multi-leveled and ambiguous, but one thing is clear: we
are creating a journey in which we are complicit, not simply voyeurs.

The work enables a unique method of navigating the content and scores
high in providing a seamless encounter between the user and the
subject matter. While the artwork is described as being an interaction
between a single user and a variable content, the entire set of options
remains fixed in the computer's database. The work does not claim any
degree of "reciprocity" between the object and the user. It does not
"learn" the reader's habits. Therefore, it is not, strictly speaking,
interactive. This does not diminish the project's ability inspire repeated
visits and reward the user with unexpected discoveries. Given its non-

linear organization and randomized sequences of multiple video clips,
each user’s experience of the book is actively engaging and unique.

As a model for a different "textbook" perhaps, the project points toward
a new class of books that are constructed with the individual user in
mind and that respond with some intelligence to reader's choices. The
fact that Flax insists on preserving the essential kinesthetic aspects of
reading--the feel of the paper, the turning of the pages--implies that
certain direct forms of knowing just cannot be improved upon. However,
the use of moving images, scrolling text, and audio clips that spill
beyond the boundaries of the book have more in common with
immersive experiences such as VR than reading. This is neither a
conventional book nor an over-scaled e-book, but rather a hybrid of
traditional forms and "reactive" hi tech processes.

Christa Sommerer and Laurent Mignonneau: Interactive
Plant Growing (1993)

Austrian-born Christa Sommerer and French-born Laurent Mignonneau
teamed up in 1992, and now work at the ATR Media Integration and
Communications Research Laboratories in Kyoto, Japan. In nearly a
decade of collaborative work, Sommerer and Mignonneau have built a
number of unique virtual ecosystems, many with custom
viewer/machine interfaces. Their projects allow audiences to create new
plants or creatures and influence their behavior by drawing on touch
screens, sending e-mail, moving through an installation space, or by
touching real plants wired to a computer.

Artist's rendering of the installation showing the five pedestals with plants and the video screen.

Interactive Plant Growing is an example of one such project. The
installation connects actual living plants, which can be touched or
approached by human viewers, to virtual plants that are grown in real-
time in the computer. In a darkened installation space, five different
living plants are placed on 5 wooden columns in front of a high-
resolution video projection screen. The plants themselves are the
interface. They are in turn connected to a computer that sends video
signals from its processor to a high resolution video data projection
system. Because the plants are essentially antennae hard wired into the
system, they are capable of responding to differences in the electrical
potential of a viewer's body. Touching the plants or moving your hands
around them alters the signals sent through the system. Viewers can
influence and control the virtual growth of more than two dozen
computer-based plants.

Screen shot of the video projection during one interactive session.

Viewer participation is crucial to the life of the piece. Through their
individual and collective involvement with the plants, visitors decide how
the interactions unfold and how their interactions are translated to the
screen. Viewers can control the size of the virtual plants, rotate them,
modify their appearance, change their colors, and control new positions
for the same type of plant. Interactions between a viewer's body and the
living plants determine how the virtual three-dimensional plants will
develop. Five or more people can interact at the same time with the five
real plants in the installation space. All events depend exclusively on the
interactions between viewers and plants.

The artificial growing of computer-based plants is, according to the
artists, an expression of their desire to better understand the
transformations and morphogenesis of certain organisms (Sommerer et
al, 1998).

What are the implications of such works for education? How can we
learn from this artistic experimentation to use technological systems to
be better teachers? Educators have long recognized the importance of
two-way or multi-directional communication. Nevertheless, many
educators perpetuate the mindset of the one-way "broadcast"--a
concept that harks back to broadcast media such as radio and echoes
the structure of the standard lecture where teacher as "source"
transmits information to passive "receivers." The notion of a "one-to-
many" model that reinforces a traditional hierarchical top-down
approach to teaching is at odds with truly democratic exchange. In
Interactive Plant Growing, Sommerer and Mignonneau invert this one to
many model by providing a system for multiple users to collaborate on
the creation of a digital wall projection in real time. The system in effect
enables a real time collaboration that takes many diverse inputs and
directs them to a common goal. And this is exactly what good teaching
is. This conceptualization of critical pedagogy has been developed in
many different situations, but here is combined with technology that
mirrors its structure.

Sommerer and Mignonneau: Verbarium (1999)

In a more recent project the artists have created an interactive "text-to-
form" editor available on the Internet. At their Verbarium web site, on-
line users are invited to type text messages into a small pop up window.
Each of these messages functions as a genetic code for creating a
visual three-dimensional form. An algorithm translates the genetic

encoding of text characters (i.e., letters) into design functions. The
system provides a steady flow of new images that are not pre-defined
but develop in real-time through the interaction of the user with the
system. Each different message creates a different organic form.
Depending on the composition of the text, the forms can either be
simple or complex. Taken together, all text images are used to build a
collective and complex three-dimensional image. This image is a virtual
herbarium, comprised of plant forms based on the text messages of the
participants. On-line users help to not only create and develop this
virtual herbarium, but also have the option of clicking on any part of the
collective image to de-code earlier messages sent by other users.

Screen shot of the Verbarium web page showing the collaborative image created by visitors to
the site.
The text to form algorithm translated "purple people eater" into the image at the upper left.
This image was subsequently collaged into the collective "virtual herbarium."

In both the localized computer installations and web-based projects
realized by Sommerer and Mignonneau, the interaction between
multiple participants operating through a common interface represents a
reversal of the topology of information dissemination. The pieces are
enabled and realized through the collaboration of many participants
remotely connected by a computer network. In an educational setting,
this heightened sense of interaction needs to be understood as crucial.
Students and instructors alike become capable of both sending and
receiving messages. Everyone is a transmitter and a receiver, a
publisher and a consumer. In the new information ecology, traditional
roles may become reversed--or abandoned. Audience members
become active agents in the creation of new artwork. Teachers spend
more time facilitating and "receiving" information than lecturing.
Students exchange information with their peers and become adept at
disseminating knowledge.

Ken Rinaldo: Autopoiesis (2000)

Overview of all fifteen robotic arms of the Autopoiesis installation.

A work by American artist Ken Rinaldo was recently exhibited in Finland
as part of "Outoaly, the Alien Intelligence Exhibition 2000," curated by
media theorist Erkki Huhtamo. Rinaldo, who has a background in both
computer science and art, is pursuing projects influenced by current
theories on living systems and artificial life. He is seeking what he calls
an "integration of organic and electro-mechanical elements" that point to
a "co-evolution between living and evolving technological material."

Rinaldo's contribution to the Finnish exhibition was an installation

entitled Autopoiesis, which translates literally as "self making." The work
is a computer-based installation consisting of fifteen robotic sound
sculptures that interact with the public and modify their behaviors over
time. These behaviors change based on feedback from infrared sensors
which determine the presence of the participant/viewers in the
exhibition, and the communication between each separate sculpture.

The series of robotic sculptures--mechanical arms that are suspended
from an overhead grid--"talk" with each other (exchange audio
messages) through a computer network and audible telephone tones.
The interactivity engages the participants who in turn effect the system's
evolution and emergence. This interaction, according to the artist,
creates a system evolution as well as an overall group sculptural
aesthetic. The project presents an interactive environment which is
immersive, detailed, and able to evolve in real time by utilizing feedback
and interaction from audience members.

What are the pedagogical implications for systems such as Autopoiesis
that exhibit "emergent properties?" Participant/learners interacting with
such systems are challenged to understand that cognition is less a
matter of absorbing ready made "truths" and more a matter of finding
meaning through iterative cycles of inquiry and interaction. Ironically,
this may be what good teaching has always done. So would we be
justified in building a "machine for learning" that does essentially the
same thing that good teachers do? One argument is that by designing
such systems we are forced to look critically at the current manner in
which information is generated, shared, and evaluated. Further,

important questions are surfaced such as "who can participate"; "who
has access to the information;" and "what kinds of interactions are
enabled?" The traditional "machine for learning" (the classroom) with its
single privileged source of authority (the teacher) is hardly a perfect
model. Most of the time, it is not a system that rewards boundary
breaking, the broad sharing of information, or the generation of new
ideas. It IS a system that, in general, reinforces the status quo.
Intelligent machines such as Rinaldo's Autopoiesis can help us to draw
connections between multiple forms of inquiry, enable new kinds of
interactions between disparate users, and increase a sense of personal
agency and self-worth. While intelligent machines will surely be no
smarter than their programmers, pedagogical models can be more
easily shared and replicated. Curricula (programs for interactions) can
be modified or expanded to meet the special demands of particular
disciplines or contexts. Most importantly, users are free to interact
through the system in ways that are suited to particular learning styles,
personal choices, or physical needs.

IMPLICATIONS FOR ART AND EDUCATION

Interactive artworks of the future will enable interactions that are at once
personal and universal. These interactions will be characterized by a
subtle reciprocity between the body and the natural environment, and
an expanded potential for self-knowledg and learning. Truly interactive
experiences are already empowering individuals (consider the
"disabled" community or autistic learners, for example).

Returning to various theories of interaction (particularly those of Ellen
Wagner), several recommendations for artists emerge that begin to
trace a trajectory for the education of the interactive artist. They include
training on and empowerment with various technologies; understanding
media-structured feedback loops (1) and methods for enhancing
"mutual recriprocity"; rethinking where meaning is constituted (cognitive
theory is now suggesting that "meaning" is seen as something that
happens between rather than inside individuals); and redefinition of the
roles of educators and learners. Rapid evolution in the art profession as
a whole is creating changes in the definitions and roles played by art
teachers and prospective artists.

There is no question that the uses of technology outlined here need to
be held against the darker realities of life in a hi-tech society. The
insidious nature of surveillance and control, the assault on personal
space and privacy, the commodification of aesthetic experience, and the
ever-widening "digital divide" between the technological haves and have
nots are constant reminders that technology is a double edged sword.

But there is at least an equal chance that a clearer understanding of the
concept of interaction--specifically interaction enabled by technology--
will yield a broader palette of choices from which human beings can
come together to create meaning. In watching these processes unfold,
educators will surely find new models for learning.

Notes

(1) "The feedback loop is perhaps the simplest representation of the
relationships between elements in a system, and these relationships are
the way in which the system changes. One element or agent (the
'regulator' or control) sends information into the system, other agents
act based upon their reception/perception of this information, and the
results of these actions go back to the first agent. It then modifies its
subsequent information output based on this response, to promote more
of this action (positive feedback), or less or different action (negative
feedback). System components (agents or subsystems) are usually
both regulators and regulated, and feedback loops are often multiple
and intersecting (Clayton, 1996, Batra, 1990)." (Morgan, 1999)
