As many readers know, this digest is gatewayed to the USENET group comp.ai.neural-nets. In fact, submissions to that (open) bboard also come to me and I often edit them for this Digest. However, the level of discussion there has been quite high and I've given priority to submissions sent directly to me, rather than the USENET postings. However, since much of the discussions are interesting and relevant (though now not so timely), I will send several issues of this Digest next to week to catch up (after wading through the best postings). I may try to put out Digests more frequently, but I'd rather keep the volume low and quality high... if possible. The current issue contains calls for papers, conference announcements, technical reports, and academic positions. As readers will recall, I try to group these types of submissions together in a single issue and keep the "discussions" separate. BTW, I hope to see many of you at ICNN this June. I just got my travel request approved! -Peter Marvit Immoderator ------------------------------ Subject: network meeting announcement for distribution From: mike@bucasb.BU.EDU (Michael Cohen) Date: Fri, 10 Mar 89 12:22:14 -0500 NEURAL NETWORK MODELS OF CONDITIONING AND ACTION 12th Symposium on Models of Behavior Friday and Saturday, June 2 and 3, 1989 105 William James Hall, Harvard University 33 Kirkland Street, Cambridge, Massachusetts PROGRAM COMMITTEE: Michael Commons, Harvard Medical School Stephen Grossberg, Boston University John E.R.

The level of presentation is aimed at a highly capable and well prepared audience. After the first two Courses (Vignieu, France in 1985; Oslo, Norway in 1987), the Swiss Group for Artificial Intelligence and Cognitive Science (SGAICO) is happy to announce that the third course in 1989 will take place in Neuchatel (Switzerland). With respect to evaluations of previous courses, ACAI'89 will focus on two major topics, namely advanced knowledge representation and the methodology of knowledge engineering. Knowledge engineering and its related topics are not restricted to expert system development methodology exclusively but to the development of AI systems in general. It is well recognized that the lack of an established theory and methodology is one of the most crucial issues within AI and pertinent to most of current research and development efforts. The course in 1989 will try to highlight different approaches to those problems and should lay the grounds for interesting and productive discussions. The course is structured into the following main components A series of lectures are to cover advanced concepts in the field of knowledge "handling" in general as well as in its various subfields, e.g. knowledge acquisition, knowledge representation, knowledge verification, and the entire development of "intelligent" systems, etc. Tutorial-style lectures, hands-on training, and case-studies should expose methodology and techniques together with pertinent problems, solutions, and limitations. These detailed, practical and even technical lectures and workshops should provide the opportunity to gain insights and experiences with current "hot topics" in AI and allow participants to evaluate these new trends with respect to their own work. Theory lectures will also cover the general philosophical and epistemological background of AI. The topics relevant to that discussion, e.g. the relation of logic or of empirical methodology to AI, the deep questions about the "nature" of mind, etc., need to be discussed and reflected by the community of advanced AI workers. In general, there is not enough time to cover these issues in congresses and workshops. Also, hopefully these lectures could provide some means of integration for people working within the many different subfields of AI. - ---------------------------------------------------------------------- Course site Neuchatel, the beautiful course site in the French speaking part of Switzerland, is within easy reach of public transportation from all over Europe. It is located at the border of Lake Neuchatel and at the foot of the Jura mountains. It is part of the charming littoral with its picturesque villages, old boroughs, vineyards, fields, and woods. Together with its university, Neuchatel is well prepared to provide the participants with a pleasant working atmosphere as well as enjoyable surroundings for sports, leisure, and weekend journeys. - ---------------------------------------------------------------------- The lectures The speakers are all well known within AI and a fair description of their work cannot be given within the limited space of this announcement. A large number of reference points may be found in books, scientific journals, conference proceedings a.s.o. (preparatory reading lists will be sent to the participants). Some of the topics to be presented and discussed at ACAI'89 within the general perspective of advanced knowledge representation and methodologies of knowledge engineering are: Belief Systems, Conceptual Graphs, Connectionist Principles of Knowledge Representation, Deep Reasoning, Development Strategies for Knowledge-based Systems, Foundations of AI, Functional Approach to Knowledge Representation, Learning, Metaphors, Natural Language Issues, Philosophical Issues, Role of Logic, Second Generation Expert Systems, Situations and attitudes, Statistical Inference, Symbolic and Neural Modeling Paradigms. The lectures will be held in a tutorial style, the necessary prerequisite to follow the classes is some background and knowledge of the basic themes and techniques of AI (e.g. inference mechanisms, search), basic representation formalisms (e.g. logic, semantic networks), and some experience with the more applied side of AI, namely research traditions (e.g. solved and unsolved problems) as well as applications of AI (e.g. implementation, programming). The structure of the course is based on the lectures, which will be held mainly in morning and afternoon sessions. For special interest groups, evening sessions may be organized on request (e.g. mini- tutorials, demonstration of software, presentation of whole research groups). Another part of ACAI'89 will be devoted to discussions, round tables, demonstrations, and expositions. There will also be space and time to present and discuss the participants own work with lecturers and other participants. In this respect, the organizers will try to arrange informal meetings in small groups having common interests. In order to facilitate discussions and the exchange of ideas, a "poster exhibition" will allow participants to present their own work in the pertinent fields. Participants who are willing to give demonstrations should contact the organizers to provide the necessary infrastructure. - ---------------------------------------------------------------------- The Small Print Organization ECCAI (European Coordinating Committee for Artificial Intelligence) SGAICO (Swiss Group for Artificial Intelligence and Cognitive Science) Course Location University of Neuchatel, Switzerland Dates Deadline for application: 15 April 1989 (reception of application form) Notification of acceptance: 1 May 1989 Payment of course fees: 1 July 1989 Arrivals: Participants will arrive Monday, 7 August in the evening Lectures start at Tuesday, 8 August and last until Wednesday, 16 August.

The Workshop will be held at the Automation & Robotics Research Institute (ARRI) of the University of Texas at Arlington (Riverbend Campus), located at 7300 Jack Newell Blvd S., Fort Worth, Texas, 76118. The recommended hotel for out-of- town registrants is the Sheraton Centre Park Hotel near Arlington Stadium, and D/FW Airport. MIND Workshop rate is $59 per night. Make reservations before April 27: Telephone 1-800-442-7275. This well-known series of workshops provides researchers and students with a unique opportunity to focus on a single timely and important topic each year with a friendly and informal setting between the "Coasts". All presentations are given in a single series (no parallel sessions). Previous workshops have featured such well-known speakers as Harold Szu, Harry Klopf, Dan Bullock, and Karl Pribram. The focus for the 1989 Workshop is the role of neural network methods in the coordination of sensory perception and motor control signal generation. The scope of the presentations will span the spectrum from biological sensorimotor transductions to neurocomputing models and paradigms. The emphasis is on recent progress and enlightening new problems and approaches. Key speakers for this year's workshop will include Rich Sutton, James Houk, and Michael Kuperstein and Dan Bullock. Registration fee is $50 ($25 for students, $40 for MIND members). Lunch will be catered both days for an additional fee of $30. Due to sparse dining in the vicinity of ARRI, lunch reservations are recom- -mended. A registration form follows. Abstracts will be received and reviewed until April 20 and selected speakers will be notified the following week. Abstracts will be distributed to all registrants.

Brittleness in the face of noise, novelty, and uncertainty is a well-known failing of symbolic problem solvers. The goals of this Workshop are to characterize the features of task environments that cause brittleness, to investigate mechanisms for decreasing the brittleness of symbolic problem solvers, and to review case histories of implemented systems that function in task environments high in noise, novelty, and data of uncertain relevance. Topics of interest for the Workshop include the following. Analysis of task environments: Definitions of noisy, novelty, and uncertain relevance; exploration of related concepts in general systems theory or logic; parameters for characterizing task environments; knowledge engineering strategies. Mechanisms for addressing noise and novelty: Plasticity and learning; constructive problem solving; fragmentation of knowledge structures; dynamic modification of rules, schemata, or cases; coherence maintenance; adaptive control mechanisms. Representations: Data structures allowing dynamic abstraction and modification; representation of ``unstructured'' knowledge; knowledge implicit in control or learning procedures; ordering of knowledge structures; tradeoffs between explicit and implicit knowledge representation. Implementation issues: Implementing symbolic problem solvers on parallel machines; concurrency control strategies; integrating symbolic systems with artificial neural networks; general systems integration. Researchers interested in participating in the Workshop are invited to submit abstracts describing work in any of these topic areas. Format. All participants will present their current work, either as a brief oral report or as a poster. Most presentations will be posters, as these provide the greatest opportunity for presentation and discussion of technical details. Presentations will be on the first day of the Workshop, followed by discussions in working groups organized by application domain and a panel discussion on the second day. Attendance at IJCAI Workshops is limited to fifty participants. Participants not registered for IJCAI must pay a $50/day fee. Abstract Submission. Please submit a 1 page abstract of the work to be presented, together with a cover letter summarizing previous work in relevant areas and expected contribution to the Workshop, to Mike Coombs, Box 30001/3CRL, New Mexico State University, Las Cruces, NM 88003-0001 USA, by 15 May 1989. Authors will be notified as to acceptance by 1 June 1989. Accepted abstracts will be distributed at the Workshop.

In particular, after learning a set of stimuli modeled after distinct groups of odors, the simulated network's initial response to a cue indicates only its group or category, whereas subsequent responses to the same stimulus successively subdivide the group into increasingly specific encodings of the individual cue. These sequences of responses amount to an automated organization of perceptual memories according to both their similarites and differences, facilitating transfer of learned information to novel stimuli without loss of specific information about exceptions. Human recognition performance robustly exhibits multiple levels: a given object can be identified as a vehicle, as an automobile, or as a Mustang. The findings reported here suggest that a function as apparently complex as hierarchical recognition memory, which seems suggestive of higher `cognitive' processes, may be a fundamental intrinsic property of the operation of this single cortical cell layer in response to naturally-occurring inputs to the structure. We offer the hypothesis that the network function of superficial cerebral cortical layers may simultaneously acquire and hierarchically organize information about the similarities and differences among perceived stimuli. Experimental manipulation of the simulation has generated hypotheses of direct links between the values of specific biological features and particular attributes of behavior, generating testable physiological and behavioral predictions.

It was found that repetitive sampling allows the network to form and read out a sequence of different representations of a stimulus, denoting information ranging from the membership of that stimulus in a group of similar stimuli, to specific information unique to the stimulus itself. This led us to the hypothesis that the combination of particular cellular physiological features, anatomical designs, and repetitive sampling performance, allows cortical networks to construct perceptual hierarchies (Lynch and Granger, 1989)*. Those initial simulation experiments did not address what is presumably an essential feature of repetitive sampling: namely, the interaction between the cortex and its inputs. The present paper reviews both our isolated cortical simulations and our first efforts to explore the issue of interaction between cortex and peripheral structures. New findings indicate that the mechanism of repeated sampling enables active analysis of stimuli into their learned components. *[Lynch, G. and Granger, R. (1989).
