ADAPTIVE NEURAL METHODS FOR MULTIPLEXING ORIENTED EDGES Jonathan A. Marshall Department of Computer Science University of North Carolina at Chapel Hill Chapel Hill, NC 27599-3175 Edge linearization operators are often used in computer vision and in neural network models of vision to reconstruct noisy or incomplete edges. Such operators gather evidence for the presence of an edge at various orientations across all image locations and then choose the orientation that best fits the data at each point. One disadvantage of such methods is that they often function in a winner-take-all fashion: the presence of only a single orientation can be represented at any point; multiple edges cannot be represented where they intersect. For example, the neural Boundary Contour System of Grossberg and Mingolla implements a form of winner-take-all competition between orthogonal orientations at each spatial location, to promote sharpening of noisy, uncertain image data. But that competition may produce rivalry, oscillation, instability, or mutual suppression when intersecting edges (e.g., a cross) are present. This "cross problem" exists for all techniques, including Markov Random Fields, where a representation of a chosen favored orientation suppresses representations of alternate orientations. A new adaptive technique, using both an inhibitory learning rule and an excitatory learning rule, weakens inhibition between neurons representing poorly correlated orientations. It may reasonably be assumed that neurons coding dissimilar orientations are less likely to be coactivated than neurons coding similar orientations. Multiplexing by superposition is ordinarily generated: combinations of intersecting edges become represented by simultaneous activation of multiple neurons, each of which represents a single supported oriented edge. Unsupported or weakly supported orientations are suppressed. The cross problem is thereby solved.

CLARIFICATION OF THE CALL FOR PAPERS The Thirteenth Annual Meeting of The Cognitive Science Society August 7th - 10th 1991 Chicago, Illinois In order to avoid overlapping the submission date for the Machine Learning Conference and give authors as much time as possible to prepare their papers, we have extended the deadline for Cognitive Science 1991 such that papers must be RECEIVED BY MARCH 18TH, 1991. We are also requesting that papers be limited to eight (8) pages to better approximate their final camera ready form. Authors should submit five (5) copies of their papers in hard copy form. All paper submissions should be sent to: Cognitive Science 1991 Department of Computer Science University of Chicago 1100 East 58th Street Chicago, IL 60637 Papers will be accepted either for presentation as talks or posters. Authors are encouraged to submit new work to the poster sessions. They provide a less formal forum for introducing work in its early stages. Length: Papers should be 8 pages long (excluding title page); have 1 inch margins on top, bottom, and sides; and use no smaller than 10pt type. Camera ready versions of papers will be required only after authors are notified of acceptance. Title Page: Each copy of the paper must include a title page, separate from the body of the paper. This should contain: 1. Title of the paper. 2. Full names, postal addresses, phone numbers, and email addresses (if available) of all authors. 3. An abstract of 100-200 words. 4. The area/subarea in which the paper should be reviewed. 5. A note stating whether the first author is a student and should thus be considered for the David Marr award. Time Table: In order to avoid overlapping the submission date for the Machine Learning Conference, we have extended the deadline for Cognitive Science such that papers must be RECEIVED BY MARCH 18TH, 1991. Notification of acceptance or rejection will be made on or before April 24th, 1991 with camera ready versions of papers due May 20th. Symposia: Symposium proposals should include a single page describing the issue or issues that the panel will address, followed by a page for each participant describing relevant work. In general, we recommend that individuals interested in chairing symposia contact the Program Chairs as soon as possible so that details of personnel and content can be discussed. Videotape/Computer Presentations: Videotape and computer presentations will be made during the poster sessions. We are interested in presentations that demonstrate results in the areas of: Artificial Intelligence, Protocol analysis, Educational tools, and Cognitive Ethnographic studies. Authors should submit one copy of a videotape of 15 minutes maximum duration, accompanied by a submission letter that includes: Title; names, addresses, phone numbers, and email addresses of all authors; three copies of an abstract of one to two pages in length. Researchers wishing to present computer demonstrations should contact Kristian Hammond as soon as possible to discuss review criteria and ensure machine availability.

Psychology Software News is published in the UK by the Computers in Teaching Initiaitve (CTI) Centre for Psychology with the support of a Government grant. The publication is now being made available internationally to promote a wider discussion of the use of educational technology in psychology teaching. Psychology Software News provides information on the use of computers in the teaching of psychology and offers a forum for discussion about the latest developments in information technology and educational innovation. The Newsletter is less formal than Journals such as Behavior Research Methods, Instruments, and Computers, although it does include a section for peer-reviewed articles. Psychology Software News is published three times a year. The editors welcome submitted articles or items for review. Regular features of the Newsletter include articles on computers and teaching practice, on educational innovation and on software development as well as reviews of software.
