Subject: 3D medical imagery slices now available
This file contains 1 data set MRI_RAW_HEAD
The RAW data is the original MRI_SIGNA_GE data with 256 monochromic
greyscale values. It contains 124 slices of 256x256x16 bits
Each slice has a header of 14336 bits.
There is a program that reads the whole directory, and saves each slice
in a 2D buffer (one slice at a time). After taking the header off and
reading one slice in buffer, it moves to next slice and reads that one
in the same buffer. So note that the buffer is dummy array and if you
want to save each slice you have to read that slice from the buffer and
save it into another. Or you can save the whole 3D data set in a 3D array.
To do so follow the instructions in the program.. you also would need at
least 24 Mbytes of RAM to save the whole data-set in a 3D array.
This program is an honest to god "C" program and you should be able to
compile it with any comercial "C" compiler. Unix User follow this:
cc readimages.c
mv a.out readimages
readimages or ./readimages (depending how you set up your system)
the program will ask you the following questions.
**input directory name
You type MRI_RAW_DATA (or the path to the image dir.)
**input file name
You type file
**Enter the number for the first image being loaded:
You type 10 (or any number 5<n1<124)
**Enter the number for the last image being loaded:
You type 125 (or any number n1<n2<124)
**Enter the Z value between slices in mm:
You type 1.5 (this is to get dimensions right)
It's that simple....
Please forward all question and bugs to shahidi@vizlab.rutgers.edu
good luck..
ps. There is a fully segmented data set of head also available via request.

Test on Image Understanding
Dear (potential) Test - participants,
The ISPRS Working Group III/3 has organized a Test on Image Understanding.
The main topic of this test is to recognize and reconstruct man made objects
in digital images. To this end not only mere images are provided, but
furthermore different kind of additional information, like, stereo images,
color images, GIS-ground truth, DTM's - a sort of range images. The data
has been distributed in April 1994 via anonymous ftp
(ftp://ftp.ifp.uni-stuttgart.de:/pub/wg3 - see readme and documentation
files in that directory for more information)
Now, the deadline for the test is coming closer (April 1995!). In order to
get an impression of how many people are planning to send in their results,
I'd like to get some information from you:
o which datasets are you using ?
o suburb
o flat
o glandorf
o remstal
o what kind of problem are you working on ?
o detection/reconstruction of houses
o detection/reconstruction of streets
o detection/reconstruction of land-parcels
o landuse classification
o derivation of digital terrain model (DTM)
o other, namely: .........

Well, it depends how your circle gets transformed. If it is an
AFFINE transformation (i.e., parallel lines remain parallel) then
the centre of the ellips IS the projected centre of the circle.
If the transformation is more generally a PROJECTIVE one (as is the
case with, e.g., a photograph of a flat object like a circle)
you CANNOT decide where the centre is; i.e.: an ellipse can be
the projection of the same circle in different ways, transforming
the centre to different positions.
Thus, it is also NOT true, except for affine transformations, that
the middle of a line segment is projected onto the middle of the
projected line segment, as was suggested in the last section.

Subject: Re: Help: finding true center of a perspective projected circle
Haralick and Shapiro's book, Computer and Robot Vision (?) volume 1, has an
algorithm for finding the parameters of an ellipse from a set of boundary
points. My recollection is that, once you'd found the couple of minor
misprints it was reasonably accurate provided that the boundary points were
well distributed around the ellipse.

Subject: Re: Efficient Gaussian Pyramid Computation [VISION-LIST digest 14.11]
From: Louis Brassard <brassard@cs.sfu.ca>
Subject: Efficient Gaussian Pyramid Computation
I am looking for an efficient way to convolve an image with a set of
gaussian kernels of standard deviations: 1 ,2, 4, 8, 16, 32 . I would like
the result to be a good approximation of the continous gaussian filtering.
In "The Pyramid as a Structure for Efficient Computation" , Burt proposes
an efficient computational method. But this method seems to me a poor
approximation of Gaussian filtering.
Burt, being one of the inventors of this kind of approach, certainly knows
what he's talking about...Does he use a rectangular filter, iterated three to
six times, to approximate a Gaussian filter? This method is very efficient and
actually a very good approximation. The point is that you won't get exactly
the sigma you might want, but usually you can find a set of parameters that
will yield a value very near to the intended one. (This approach is based, of
course, on the central limit theorem of probability theory.) Whether you want
the pyramid structure or not depends on details of your application; in
general, the pyramid is the correct approach from a theoretical point of view
(no unecessary oversampling) and reduces the amount of computation
drastically, while requiring more work to find all the filter responses
belonging to any one pixel, for instance.

Subject: Looking for refs on "solving jigsaw puzzles by computer"
I am looking for any references to the use of computers in solving the
"jigsaw puzzle" problem: given a large set of irregularly shaped
"pieces" (either flat or three dimensional), find subsets whose edges
seem to fit together in some sense.
I suppose a lot has been done and written about this problem.
I am searching computer science journals, but there must be many more
papers scattered all over the applied fields, and I don't
have any clue on where to look.
Here are some real-world "jigsaw puzzles" I can think of:
- ancient manuscripts (e.g. the Dead Sea Scrolls)
- pottery fragments
- broken statues, frescoes, stonework
- ancient continents (Pangaea, Gondwana, ...)
- biochemistry (enzyme/substrate, antibody/antigen, ...)
- paleontology
- forensic medicine
- computer vision
- recreational puzzles
I would be grateful for any pointers to papers, people, or
institutions relevant to the use of computers for solving
such "puzzles".
Since news here expire after a few days, please send your reply by
e-mail to stolfi@dcc.unicamp.br, in addition to (or instead of)
posting it to the net. I will gather the replies in a digest
and post the result to this newsgroup.

What I need is to add 1/f noise to a set of images I have. 1/f noise
is defined as a stochastic process whose power spectrum is such that
1
S(f) ~ ---
|f|^(alpha)
When using wavelet decomposition, this implies that the noise variance
decreases geometricaly at finer resolution levels.

From: mjs@hpp.Stanford.EDU (Marcel Schoppers)
Organization: Robotics Research Harvesting
Subject: visual identification+servoing subcontract offered
Hi. I'm writing a proposal for which I could use the help of a well-
known vision/image processing researcher (others need not apply). Interested
parties should make themselves known to me ASAP, the proposal deadline is
rapidly approaching.
Marcel Schoppers
mjs@hpp.stanford.edu
Problem:
My immediate objective is to servo a robot hand to pick up a chess
piece from a chess board with a game in progress. (If anyone knows of similar
work, please tell me.) Your objective is to process (a few) video images --
given knowledge of the usual shapes of the pieces to be picked up, estimates
of where the desired piece and the camera are in space, and the expectation
that the piece is the right way up -- to identify the desired piece, both on
the board and off the board, and get a position estimate that is sufficiently
accurate for grasping, say < 0.1" error. For extra marks later, but much less
importantly for now, we might get into locating the pieces when they've been
randomly scattered on a board or table, or even in a box.
I envision a tiny black/white camera attached to the robot hand, and
the hand can be used specifically to move the camera, but hand motion is not
very repeatable by robot standards, perhaps also < 0.1", so triangulation may
not help much. Given the circuits I expect to use, you'll get digitized images
of 160x160 pixels (or part thereof), uploaded via parallel port to a PC clone,
a few times per second at most. The image processing should be fast enough to
localize and grasp a specified chess piece a few seconds after you know which
one is wanted.
If necessary, you may make use of an infra-red narrow-beam (2dg or 10dg
half-width) range sensor (the Hamamatsu Photo IC and LEDs).
Beyond the chess application I have a more general interest in servoing
robot hands to pick up a small range of things from (say) an office desk, with
and without prior knowledge of position/orientation, but the chess application
comes first.
Schedule:
I'm writing the proposal right now (to the NIH), it's due on April 15.
If you're the subcontractor I'll need from you:
- your Statement of Work and your budget,
- a signed letter from you saying you agree to do that work at that price,
- your resume and publications list (which we will shorten),
- whatever you can show to indicate ability to perform on time and within
budget,
several days before April 15th, and all for inclusion in the proposal.
The work would be done in two phases (it'll be an SBIR type contract).
If awarded, Phase I would start in November and go for 6 months, and would try
to show that the core of the problem is solvable enough to be useful. At the
end of Phase I (May 1996) we write a Phase II proposal including your write-up
of your results and spelling out how you intend to robustify/generalize. If we
win a Phase II contract too, we start the Phase II work in November 1996 and go
for two years until November 1998.
Constraints:
Your Phase I work is constrained by law to a budget of < $30K. Your
Phase II work is constrained by law to a budget of < $200K. Both of those
limits may be lowered by my allocation decisions and detailed budgeting. The
good news is that since this is SBIR money, once we've won it won't be taken
away by Congress changing its mind; only *I* could terminate your contract.
The Federal Government wants us to be simultaneously cutting-edge and
risk-free, so we have to hedge. The Phase II money is for reducing a novel
idea to robust practice, the Phase I money is for demonstrating that Phase II
is going to work (and for writing the Phase II proposal). In addition to these
fairly normal SBIR objectives, however, my personal income depends on this in
the most direct way, if we screw up I'm out of a job, and I want to make it not
just to the Phase II contract but all the way to something marketable. While I
am a researcher myself and so understand research risk pretty well (see the
latest issue of the AI Journal) I'm also a business person now, wanting to buy
a specific capability from you, not give you a research grant to spend any way
you like (though of course there'll be some wiggle room).
You must be willing to hand over your source code to me and let me
modify, duplicate and sell it as I wish.
About Me:
I got my PhD in 1989 from the U of Illinois/Urbana in AI planning, have
worked on DoD and NASA contracts from 1986-1992 under the auspices of a small
business (not mine), and have now started up my own business. Despite being
constantly in business I'm still managing to publish 2-3 research papers per
year in AAAI, planning conferences, and journals. Presently I'm working a 2-
year contract for NASA, but given how long the funding cycle is, it's time to
look for more income.
I've managed subcontractors (such as you would be) since about 1989.
If you're interested, you can either email me as mjs@hpp.stanford.edu, or for
efficiency's sake you can phone me at 415-369-4222 during California office

Subject: CFP : Fractal Image Encoding and Analysis ASI
CALL FOR PARTICIPATION
***********************
Fractal Image Encoding and Analysis
====================================
a NATO Advanced Study Institute
================================
July 8-17, 1995
at the
Reso Royal Garden Hotel
Trondheim, Norway
Objectives
============
The Advanced Study Institute (ASI) is an expository meeting in which invited
speakers present new advances in fractal image encoding and analysis. The
meeting has two main objectives: First, the ASI will focus on presenting
material that is not taught elsewhere and that is not available from any one
source. Researchers with fractal image analysis and encoding backgrounds will
demonstrate their techniques to each other in order to advance both fields.
Workshops in both areas will discuss specific implementation issues and generate
a list of interesting unsolved problems.
Scope
======
Topics to be covered include, but are not limited to:
o Fractal Analysis and Modeling of 2D data.
o Multifractal image segmentation
o Encoding methods: VQ, classification, breaking the time complexity, search
strategies.
o Decoding methods: pyramid representation, pixel chasing, finite step
decoders, matrix inversion.
o Video and Color encoding.
o Analysis and Implementation Workshops.
Structure/Participation
========================
Four invited talks will be given each day, followed by one or two shorter
selected talks by participants in the institute. A poster session will be held
during the breaks and in the evenings. The institute will also include two
workshops, one on image encoding and one on image analysis.
Participants wishing to present talks or posters should e-mail, fax, or mail an
extended abstract (2-3 pages) describing their proposed lecture/poster-session
to the ASI (see contact information) before April 15, 1995. NATO asks that

Subject: Reminder: Embodied Language Submission Deadline April 14th
Call for Participation
EMBODIED LANGUAGE AND ACTION
AAAI 1995 Fall Symposium Series
November 10-12, 1995
MIT, Cambridge Massachusetts
This symposium focuses on agents that can use language or similar
communication, such as gesture, to facilitate extended interactions in
a shared physical or simulated world. We examine how this embodiment
in a shared world both stimulates communication and provides a
resource for understanding it. Our focus is on the design of
artificial agents, implemented in software, hardware, or as animated
characters. Papers should clearly relate the technical content
presented to one of the following tasks:
--- Two or more communicating agents work together to
construct, carry out maintenance on, or destroy a physical
or simulated artifact (Collaborative Engagement)
--- An agent assists a human by fetching or
delivering physical or software objects.
The human communicates with the agent about what
is to be fetched or delivered to where.
(Delivery Assistance)
We solicit papers on the following issues (not to the exclusion of
others):
-- Can task contexts act as resources for communication by
simplifying the interpretation and production of communicative acts?
-- How does physical embodiment and its concomitant resource
limitation affect an agent's ability to interpret or generate
language?
-- Can architectures designed to support perception and action support
language or other forms of communication?
-- How can agents to mediate between the propositional representations
of language and the (often) non-propositional representations of
perception and action?
-- What tradeoffs exist between the use of communication to improve
the agents' task performance and the additional overhead involved in
understanding and generating messages?
-- Do differences between communication used to support concurrent task
execution and communication used to support planning, reflect deeper
differences in agent ability?
-- What is the role of negotiation, whether of task responsibilities,
or of reference and meaning, in such situated task environments?
Interested participants should submit either (1) a paper (in 12 pt
font, not to exceed 3000 words), or (2) a brief position statement.
Send contributions, plain ascii or postscript, by April 14, 1995 to
ian@ai.mit.edu. Notification of acceptance will be given by May 19,
1995. Material to be included in the working notes of the symposium
must be received by August 15, 1995.

Course Abstracts
Computer Models of Emergent Cognition
Robert French (Indiana University, USA)
This course starts by first considering why we even think
that modeling human cognition on a computer might be
possible. This is followed by a general presentation of
papers related to Turing's celebrated way of looking at the
question, "Can Machines Think?" There will then be a
presentation of and discussion of arguments for and against
the Physical Symbol System Hypothesis, the basis of
traditional computer modeling of intelligence. There will
then be a similar treatment of emergent models of cognition,
in particular, connectionist models of cognition and
classifier systems. This will lead to the conclusion that the
future of cognitive modeling lies in the integration of top-
down and bottom-up models. We will examine one approach to
this, starting from an older top-down perspective, that
focuses on a stochastic computer-model of analogy-making. We
will see two other approaches to the same endeavor of
integrating top-down and bottom-up processing that start from
a connectionist framework. Throughout, emphasis will be put
on the fundamental inseparability of representation-building
and processing.
Robert French
Robert French received his Bachelor's and Master's degrees in
mathematics before leaving for France to work as a
translator. Upon completion of the translation into French
of Douglas Hofstadter's Godel, Escher, Bach, he returned to
the U.S. to do his Ph.D. in computer science at the
University of Michigan with Hofstadter. The topic of his
dissertation as well as his forthcoming book (MIT Press) is
the computer modeling of analogy-making. His other major
areas of research are the problem of catastrophic
interference in connectionist networks and the organization
of bilingual memory. He is currently a member of the Center
for Research on Concepts and Cognition at Indiana University
and an honorary fellow in the department of psychology at the
University of Wisconsin.
Hemispheric Mechanisms in Cognition
Eran Zaidel (UCLA, USA)
The course will review language and cognitive functioning in
commissurotomy patients and will discuss interhemispheric
relations in split and normal brains. The problems of
hemispheric specialization, independence, and control will be
discussed. The disconnection syndrome, partial callosal
section and subcallosal transfer will be described. Methods
and models of studying interhemispheric relations in normal
and split brain will be outlined. Degrees of modularity
(hemispheric independence) as well as interhemispheric
effects will be discussed. Individual differences will be
considered.
Eran Zaidel
Eran Zaidel received his PhD from Caltech working with Roger
Sperry. He is currently a Professor of Psychology at UCLA. He
has been a member of the Editorial Boards of Brain and
Cognition, Neuropsychologia, Neuropsychology. He has been the
Secretary of the Academy of Aphasia and got the NIMH Research
Scientist Award. He is interested in interhemispheric
relations and cooperation in processing hierarchical
patterns, in lexical processing, and in problem solving; in
hemispheric control in the normal brain; in split brain
research.
Cross-Linguistic Studies of Language Processing
Elizabeth Bates (UCSD, USA)
The course will cover more than 20 years of cross-linguistic
research on language learning and language use, in normal
individuals and in patients with focal brain injury. We will
begin with a general introduction to the Competition Model, a
theoretical framework developed by Bates, MacWhinney and
colleagues to deal with quantitative as well as qualitative
differences in knowledge and performance across structurally
distinct language types. This section will stress the
contrast between interactive-activation and modular theories
in psycholinguistics, and contrasting computer metaphors that
underlie each approach (i.e. neural networks vs. serial
digital computers). After this theoretical overview, we will
review cross-linguistic findings within the Competition Model
framework, divided into four areas: (1) sentence processing
in normal adults (comprehension, production, grammaticality
judgment, morphosyntactic constraints on lexical access), (2)
language development in normal children (with a special
emphasis on studies of sentence comprehension), (3)
bilingualism and second-language learning, and (4) cross-
linguistic studies of language processing in aphasia.
Elizabeth Bates
Elizabeth Bates is a Professor of Cognitive Science and
Psychology at the University of California, San Diego. She
is the Durector of the UCSD Center for Research in Language
and the Director of the UCSD Project in Cognitive and Neural

Discourse Processes, Journal of Speech & Hearing Research,
Infant Behavior & Development, Brain and Cognition, Language
and Cognitive Processes, Brain and Language, Psychological
Review, Rassegna di Psicologia, Journal of Child Language,
Cognitive Development.
Aphasia Research
Nina Dronkers (UC at Davis, USA)
This course will present descriptions of the different types
of aphasia, the brain regions that underlie them, and the
applications of neuroimaging to the study of aphasia. It
will begin with a discussion of the history of aphasiology
and the characteristics of the different language disorders.
Aphasia classifications will be reviewed and, if possible,
videotapes of patients exhibiting the various disorders will
be shown. The latter part of the course will review the
traditional language areas and models of language processing
and how these apply to aphasia. Participants will also learn
to view CT and MRI scans of patients with aphasia and to
apply this knowledge to both their basic understanding of
language processing in the brain and to the management of
patients with aphasia.
Nina Dronkers
Nina Dronkers is the Chief of the Audiology and Speech
Pathology Service at the VA Northern California System of
Clinics. She is also an Adjunct Assistant Professor at the
University of California at Davis in the Departments of
Neurology and Linguistics. She received her Ph.D. in
Neuropsychology at the University of California, Berkeley.
Since that time, she has conducted research at the VA
Martinez in the areas of aphasia and other cognitive deficits
resulting from brain injury, the cerebral localization and
lateralization of language, and studies of semantic priming
in aphasic and normal individuals. She has received several
grants to support this research, primarily from the National
Institutes of Health, the VA Department of Medical Research,
and the National Science Foundation. Her publications cover
several issues in aphasiology and the effects ofbrain injury
on the linguistic system. She is an active member of the
Academy of Aphasia and the International Neuropsychological
Society.
Topics in Cognitive Linguistics
Elena Andonova (NBU, Bulgaria)
This course is intended as a discussion of selected topics of
cognitive linguistics rather than as a survey of the field.
Basic notions and principles will be introduced. The
connections between cognitive linguistics and another fast-
growing field, discourse analysis will be examined.
Correspondences between the mechanisms of metaphorization and
discourse strategies will be viewed in light of the
relationship between cognition and communication. In this
connection, the idea of euphemization is introduced both as a
development of metaphorization and as a discourse process.
Adopting the point of view of critical discourse analysis
which shuns the 'consensus' notion of social communication
would require us to consider the constructive function of
language and diachronic changes.
Elena Andonova
Elena Andonova is an Assistant Professor in Cognitive
Linguistics at the Department of Cognitive Science, New
Bulgarian University, in Sofia. She has a B.A. and an M.A. in
English from Sofia University and is currently working on the
final stages of her Ph.D. with the University of Wales
College Cardiff in the United Kingdom. Her main interests in
the field of lingustics are in areas concerned with the
cognitive and communicative aspects of language, more
particularly, cognitive linguistics, metaphorization and
euphemization, (critical) discourse analysis, discourse
strategies, etc.
Parallel Pathways of Visual Information Processing
Angel Vassilev (BAS & NBU, Bulgaria)
Our unified experience of the visual world is, surprisingly,
a result of information processing within multiple parallel
retino-cortical and intracortical pathways. Anatomical and
neurophysiological data about the existence of such pathways
and particularly the methodology of classification will be
discussed. The role of separate pathways in the perception of
colour, form, motion, and stereopsis will be outlined. Recent
data on multiple cortical visual centres, obtained by brain
imaging techniques, will be presented. Attempts to
selectively test the integrity of separate pathways will be
presented. The question of how the information, contained in
the separate representations, is brought together to yield
unified experience of the visual world will be characterized
as a major target of future research.
Angel Vassilev
Angel Vassilev received his PhD from Pavlov's Institute of
Physiology in Sankt Petersburg, and a D.Sc.. degree in Sofia.
He received a postdoctoral research grant at the Department
of Psychology at the University of Pennsylvania at
Philadelphia, USA. Angel Vassilev is currently a Senior
Research Fellow at the Institute of Physiology of the
Bulgarian Academy of Sciences and a Professor of
Neurosciences at the Cognitive Science Department of the New
Bulgarian University. He is the Head of the Visual
Information Processing Laboratory. His research interests are
in the field of visual psychophysics and electrophysiology.
Colour Vision
Charles De Weert (University of Nijmegen, The Netherlands)
In a short course of 8 hours some basic aspects of colour
vision will be dealt with. The first two hours will be spent
on the technical descriptions of colour (the CIE System) such
that a proper stimulus description is ensured. A very simple
zone theoretical model of colour vision will be taken to
explain baisc colour vision phenomena. Next the discussion
will be opened on the possibly modular character of colour
vision, and special attention will be paid to a series of
isoluminance experiments. In the next two hours color
constancy will be dealt with and the final two hours will be
used to deal with the use of colour for displaying
information.

with about 50 senior research fellows and about 50 PhD
students. He is a full professor in Psychophysics at the
Nijmegen University and his main lines of research are
(still) in Colour Vision and in Binocular Vision.
Visuo-Spatial Attention
Carlo Umilta' (University of Padova, Italy)
Even in the restricted sense of a selective process,
attention refers to different phenomena. An individual may
selectively attend to information presented in a particular
modality, to information originating from a particular
position in space, to stimuli possessing a particular color
or shape, or to items belonging to a particular class or
category. The feature common to all these phenomena is that
information to which attention is selectively allocated is
processed more efficiently than non-attended information.
The course is exclusively concerned with the spatial aspects
of selective attention, i.e., with the selective allocation
of attention to a particular position in space. The first
part deals with the hypotheses of how attention shifts from
one position to another in visual space and with the
relations between attention and eye movements. In the second
part, the analogies of focal attention are illustrated and
their implications are discussed. Particular emphasis is
given to the operations that allow the control of size and
shape of attentional focus.
Carlo Umilta'
Carlo Umilta' is currently a Professor of Psychology at the
University of Padova. He is a former Director of the
Institute of Human Physiology of the University of Parma,
1983/9. He is a member of the editorial Boards of several

the Italian Neuropsychological Society as well as of the
European Society for Cognitive Psychology. He is currently
the Chair of the Executive Committee of the International
Society for the Study of Attention and Performance. His main
research interests are in the field of visual attention.
Integration of Language and Vision
Geoff Simmons (Hamburg University, Germany)
In the past two years or so, there has been a revival of
interest in the relationships between lexical meanings and
visual perception. Analyses of both of these cognitive
modalities have yielded very revealing accounts of human con-
ceptual structures and cognitive architecture, and these
accounts are expected to comple-ment and mutually constrain
each other. In this course we consider some of the evidence
and theories that have been proposed.
Spatial knowledge ? knowledge of the relative locations of
objects, and knowledge of the shapes of the objects
themselves ? is the conceptual domain where the relationships
between language and vision are most commonly sought. This
has been made possible by in-depth linguistic studies of
spatial prepositions, dimensional adjectives and other
lexical fields; and by investigations of the perception of
locations and shapes in experimental psychology and neuro-
science. We will also consider the classic work of Berlin and
Kay on color vision and color terms in the world's languages.
In the course we will examine some of the relevant empirical
evidence, and consider computa-tional models that have been
put forth in explanation. This will bring us to some deeper
questions concerning cognitive architecture: Is there a
central store of conceptual structures to which both the
linguistic and visual systems have common access? Is the
linguistic system "piggybacking" on the visual system ? i.e.
are the conceptual structures underlying linguistic meanings
formed from mental resources whose "original" function is
perceptual? Or are there instances of "perceiving for
speaking" ? i.e. is the visual system in some cases attending
to certain information solely because the linguistic system
requires it (as Annette Herskovits has suggested)?
Geoff Simmons
Geoff Simmons received a Master's degree in Computer Science
and Linguistics at the University of Hamburg in 1992. He is
presently completing a dissertation entitled "Knowledge of
Shape in Object Concepts" at the Doctoral Program in
Cognitive Science, University of Hamburg.
Analogical Reasoning:
Psychological Data and Computational Models
Boicho Kokinov (NBU, Bulgaria)
The course will focus on analogical reasoning in problem
solving. All main aspects of problem solving will be
considered: problem representation, base retrieval, mapping,
transfer, evaluation, and learning. A brief review of
psychological data on all those subprocesses will be
presented. Several models of analogy-making will be discussed
in more detail: Gentner's Structure-Mapping Engine; Holyoak
and Thagard's ACME and ARCS; Hofstadter, Mitchell and
French's Copycat and Tabletop; and the lecturer's model -
AMBR. The course will focus on the integration of various
constraints (structural, semantic, and pragmatic) on analogy-
making; on the integration and interaction of various
subprocesses (representation, retrieval, mapping, and
transfer) in analogy; on the relations between analogy and
perception, memory, reasoning, and learning; on the dynamic
context-sensitive nature of the analogy-making process.
Boicho Kokinov
Boicho Kokinov graduated in Mathematics and Computer Science
at Sofia University. He works in the field of cognitive
modeling. His main interests are in modeling human memory and
reasoning (especially analogical and diagrammatic reasoning).
He has proposed an emergent hybrid cognitive architecture,
DUAL, and several models on its basis. He is interested also
in running psychological experiments and comparing their
results with the data obtained from simulation experiments.
He leads a research project on Context effects on High-level
Cognition. He is the Director of the Cognitive Science
Program at the New Bulgarian University and a research fellow
at the Institute of Mathematics of the Bulgarian Academy of
Sciences. He is the President of the Bulgarian Cognitive
Science Society.
Philosophy of Mind
Lilia Gurova (NBU, Bulgaria)
The aim of the course is to present classical philosophical
problems and their relation to cognitive science. The mind-
body problem, the problem of intentionality and so called
qualia (also known as secondary properties or qualities) will
be discussed both in a historical perspective and from the
standpoint of the contemporary cognitive science
methodology.It is not to be expected that cognitive
scientists will solve all these problems once and
forever,probably they will not be able even to propose any
principally new solution. Philosophical problems are not the
kind of problems cognitive science must deal with. Their role
for cognitive science as well as for the other scientific
disciplines is different. Philosophical problems, taken with
their possible solutions must be regarded as patterns of
typical and important problem situations which all scientific
research may be faced with. Knowledge about these typical
situations could be useful for making optimal decisions in
every concrete problem situation.
Lilia Gurova
Lilia Gurova has a Master's degree in Electronics (Technical
University of Sofia, 1981) and Ph.D. in Philosophy of Science
(Institute of Philosophy - Bulgarian Academy of Sciences,
1988). Her Ph.D. thesis is devoted to the frame problem of AI
methodology. Now the role of problems (and/or questions) in
the organisation of human thinking is the major theme of her
scientific investigations. This theme is the point of
converging of her interests in history, philosophy and the
methodology of science, logic, philosophy of mind and
cognitive science.
Lilia Gurova is a research fellow at the Institute of
Philosophical Sciences of the Bulgarian Academy of Sciences
and a lecturer at NBU for the courses "Philosophy of Mind"
and "Thinking and Computation: A History of Ideas".
Emotion and Cognition
Cristiano Castelfranchi (CNR, Italy)
After 15 years of debate about the cognitive or pre-cognitive
nature of Emotions (see also the birth of a journal on
Cognition and Emotion), after other studies in Cognitive
Science (philosophy, linguistics, etc.) about emotions
analysis and categorisation, after new studies about
emotional development, expression, cultural relativity,
biological and social functions, and after the emergence of
computational approaches to Emotions, both to model emotional
process and the impact of emotions on action and motivation,
and after the introduction of emotional features in H-C
interaction, some of the main problems of the relationship
between Emotion and Cognition and of the model of emotional
mental states and process, are relatively clearer.
The course will review the contributions of Psychology and AI
to the understanding of emotions (especially the debate on
Cognition and Emotion). In particular, the course will focus
on the cognitive structure of emotions: a) which kind of
beliefs are necessary ingredients of emotion and determine
its activation and its character (intentionality,
appropriateness, subjective appraisal, social evaluation,
etc.); how they are organised; how are they related with
emotional goals and behaviours. b) which kind of goals are
necessary ingredients of emotional states; how they are
related with the "conative/motivational" aspect of Emotions;
how they are related with the biological or social functions
of Emotion. This structural analysis will be carefully
applied to the "anatomy" of some very relevant social
emotions: envy, shame, guilt, etc., trying to precisely
identify a typical structure of beliefs and goals, and trying
to justify such a structure also in terms of moves to induce
a specific emotion or moves to inhibit or avoid it.
Cristiano Castelfranchi
Cristiano Castelfranchi took a degree in Letters, with a
dissertation on the representation of meaning. He is a
researcher at the Institute of Psychology of the National
Research Council of Italy. From 1966 to 1976 his main
interests included generative semantics, speech acts, and
conversation. He subsequently moved on to a computational and
A.I. approach to language, developing, together with O. Stock
and D. Parisi, models of parsers with a semantic output, and
models of hybrid knowledge representation. During the same
period he developed, together with D. Parisi, M. Miceli and
R. Conte, a model of communicative and social behavior in
terms of goals. His analysis has addressed in particular:
power, dependence, interest, and exchange relationships;
influencing behavior, goal adoption, and deception; the role
played by image and self-image in social interactions, and
emotions such as envy, shame, guilt, pity, and ridicule. He
is the head of the Project for the Simulation of Social
Behavior at IP-CNR that is aimed at constructing a model of
an autonomous agent capable of social interaction by merging
both AI and cognitive studies. He has been the Head of the
Social Psychology Division and the "AI & Social Interaction"
Division of IP/CNR. Castelfranchi is the author of 9 books on
topics in Language, Emotion and Multi-Agent Modelling. He is
a member of the Editorial Board of the Italian journal of AI
and Cognitive Science "Sistemi Intelligenti".
