CALL FOR PAPERS - BRIMS 2004 13th CONFERENCE ON BEHAVIOR REPRESENTATION IN MODELING AND SIMULATION (BRIMS) In affiliation with the Simulation Interoperability Standards Organization and the Institute for Simulation and Training Arlington, Virginia 17-20 May 2004 You are invited to participate in the 13th Conference on Behavior Representation in Modeling and Simulation (BRIMS). This annual event provides a forum for scientific and technical exchange on research in the science of human behavior representation and on the application of leading-edge cognitive science to the behavior representation challenges faced by the modeling and simulation community. Application areas of interest include training, rehearsal, analysis, acquisition, planning, experimentation, and gaming. The conference enables modeling and simulation research scientists, engineers, application users, and technical communities to meet, share ideas and experiences, identify gaps in current capabilities, discuss new research directions, and highlight promising technologies. The BRIMS Conference Program Committee invites papers, symposia, panel discussions, and tutorials on topics related to the representation of individuals, groups, teams and organizations in models and simulations. Submissions are peer-reviewed and considered for selection by the Program Committee. Traditional Sessions: Paper Presentations Traditional Sessions are composed of 3 or 4 presentations on related topics. The presentations are done lecture-style, with 20-25 minutes for the presentation and approximately 5 minutes for questions. Presentations are displayed through electronic slides (e.g., PowerPoint). Paper submissions are limited to 8 pages and should describe original research that has not been published elsewhere. Papers may be submitted through the on-line submission system. If accepted, papers appear in the conference Proceedings. Please see the BRIMS Paper Guidelines for format requirements and content suggestions. The deadline for paper submissions is January 30, 2004. Interactive Session: Posters and Demos The Interactive Session involves a longer (approximately 2 hour) period of multiple simultaneous presentations and provides an opportunity for continuous interaction with conference attendees. The Interactive Session features supporting material in static wallboard/posterboard displays and/or live demonstrations of state-of-the-art applications in modeling, simulation, and training. Poster and demo submissions are limited to a 2-page extended abstract describing the research to be presented or the technology (e.g., architecture, model, task environment) to be demonstrated. If accepted, abstracts appear in the conference Proceedings. Please see the BRIMS Poster/Demo Guidelines for format requirements and content suggestions. The deadline for submissions is January 30, 2004. Symposia/Panel Discussions These are 60-90 minutes long, with several speakers presenting research and/or engaging in discussion on different aspects of a common topic that is of interest to the BRIMS community. These are not merely collections of presentations. There should be a set of common questions/issues addressed by all participants. Abstracts for symposia or panel discussions may be submitted through the on-line submission system. The 2-page abstract should provide a title for the session, identify the chair, list the participants' names and affiliations, provide a justification for why the session topic is timely and of interest, include a brief statement (approximately 250 words) from each participant summarizing the main points they will make during the session, and identify the common questions/issues each participant will address. Submissions will be reviewed by the Program Committee. If selected, these abstracts will be published in the Proceedings. Please see the BRIMS Symposia/Panel Guidelines for format requirements. The deadline for submissions is January 30, 2004. Tutorials Tutorials provide conference participants the opportunity to gain new insights, knowledge, and skills in an area related to the interests of the BRIMS community. Tutorials are presented in a lecture-and-discussion or learning-by-doing format. Tutorials may be a half-day (3 hours, plus breaks) or a full-day (6 hours, plus breaks) in duration, and will take place on Monday, May 17, 2003. Tutorial proposals may be submitted through the on-line submission system. Tutorial descriptions should include a detailed outline of the material that will be covered with time allocations and scheduled breaks. Proposals for tutorials will be reviewed by the Program Committee. If accepted, a description of the tutorial will be included in conference announcements and in the Proceedings.

However, there are commands which allow you to set the base-level or the parameters that determine the base-level if you have base-level learning enabled. The two commands that would be useful are set-base-levels and sdp. They are described in the ACT-R 4 manual which you can get at . How and when you call them would depend on how the new chunks are being created and when you need the results to really take effect. So, without knowing anything about the model I can't say much about that, but I can provide some examples of their use. If base-level learning is not enabled, then the base-level can be set directly for a chunk like this: (set-base-levels (chunk-name 5)) or (sdp chunk-name :base-level 3) If base-level learning is enabled, then you must set the creation time and references which determine the base-level: (set-base-levels (chunk-name 10 0)) where the first number is the number of references and the second is the creation time in seconds. or (sdp chunk-name :creation-time 0 :references 10) Since you said the chunks don't exist at the start, it's likely that you don't know their names in advance. So, you'll probably have to "get" the name some how and in that case you'll probably need the functional form of the commands since you'll either be evaluating some form to get the name or have it bound to a variable. So, if we assume that there is a variable called chunk-name-var with the current value of a chunk-name, then the commands would look like this: (set-base-levels-fct (list (list chunk-name-var 10 0))) or (sdp-fct (list chunk-name-var :creation-time 0 :references 10)) It's also possible when using sdp to specify a list of chunks for which one wants to set the parameters. So assuming that there are multiple variables holding chunk names one could do: (sdp-fct (list (list c-name-var1 c-name-var2) :creation-time 1)) Finally, there is a command called sdm which can be used to return a list of chunks matching a particular specification (the details are again in the manual referenced above). In particular one can use it to return the list of chunks of a specific type: (sdm isa chunk-type-name) will return the list of all chunks of the chunk-type chunk-type-name. Putting that with sdp one could then set the paramters for all of the chunks of a particular type at once like this: (sdp-fct (list (no-output (sdm isa chunk-type-name)) :creation-time -1.0) The no-output command prevents sdm from printing the chunks as well, which it would do by default. Hope that helps, and if you have any other questions let me know.

But keep in mind that ACT-R 5.0 is the implementation of a theory - and if you change the standard assumptions a lot, you leave the empirically well established ground of the theory. Manipulating the baselevel of chunks at the time of their creation depending on their type seems to be something that needs careful justification. And it introduces new (hidden) parameters. I remember work done by Erik Altmann where new chunks are assumed to be rehearsed to a certain threshold (which appears to resemble what you want). I think it is documented in the following papers: Altmann, E. M. (2002). Functional decay of memory for tasks. Psychological Research, 66, 287-297. Altmann, E. M. & Gray, W. D. (2002).

Message-ID: Dear Colleagues, please, find below the Call for Papers for MobiQuitous 04. Notice that the paper submission deadline has been postponed to February 13 (with paper registration due on February 6). We *TRULY* apologize if you receive multiple copies of this Call for Papers. *********************************************************************** PRELIMINARY ANNOUNCEMENT and CALL FOR PAPERS MobiQuitous 2004 http://www.mobiquitous.org The First Annual International Conference on Mobile and Ubiquitous Systems: Networking and Services August 22-25, 2004 Boston, Massachusetts, USA (ACM sponsorship pending) *********************************************************************** The combination of mobile and ubiquitous computing is emerging as a promising new paradigm with the goal to provide computing and communication services all the time, everywhere, transparently and invisibly to the user, using devices embedded in the surrounding physical environment. In this context, the communication devices, the objects with which they interact, or both may be mobile. The implementation of such a paradigm requires advances in wireless network technologies and devices, development of infrastructures supporting cognitive environments, and discovery and identification of ubiquitous computing applications and services. The first ACM Annual International Conference on Mobile and Ubiquitous Systems: networking and services (Mobiquitous 04) will cover all these aspects, representing a forum where practitioners and researchers coming from the many areas involved in ubiquitous solutions design and deployment will be able to interact exchanging the cross-layer experiences needed to build the overall ubiquitous systems. Areas addressed by the conference include: applications, service-oriented computing, middleware, networking, agents, knowledge management and databases. PAPERS: Technical papers describing original, previously unpublished research, not currently under review by another conference or journal, are solicited. The conference is interested in contributions addressing all the areas associated with mobile and ubiquitous architectures, infrastructure and services. Technical works clearly identifying how the specific contributions fit to an overall working solution are particularly of interest. Topics include, but are not limited to, the following feature topics: * Ubiquitous architectures and systems * Wearable computing and personal area network * Wireless technologies for mobile and ubiquitous communications (Bluetooth, ZigBee, 802.15.x, WiFi) * Wireless Internet access in ubiquitous systems * Reconfigurability and personalization of wireless network * Service discovery mechanisms, knowledge discovery, matching and composition mechanisms * Wireless/mobile service management and delivery * Security, privacy and social issues of mobile and ubiquitous systems * Peer-to-peer knowledge management * Emerging industrial/business scenarios * Multimodal interfaces (speech, video kinetic, tactile) * Smart spaces * Ad hoc and sensor networking * Localization and tracking * Context and location aware application * Multimedia encoding and transcoding * Middleware services * Agent technologies in ubiquitous, wearable, and mobile systems * Hardware and software platforms for ubiquitous systems, and testbeds * User interfaces * Toolkits, development environments, and languages for ubiquitous computing * Ontologies for mobile and ubiquitous computing SUBMISSION INSTRUCTIONS: All paper submissions will be handled electronically (see the conference web page for details).

I am not sure if it will help you, but you can set the levels of individual chunk. The way you do it depends on whether the model learns the base-levels (the :bll mechanism is on or not). If it does, then you can change the chunks' levels by defining their creation times and numbers of past references. For example, in a model of a mouse I used, there was a chunk representing the current state of a mouse (self state). Because I believed that there should not be a long time to retrieve such a chunk, I set its base level to a high value by defining the long in the past creation time (could be approx the age of a mouse in seconds) and high value of references: (set-base-levels (self 1000000 -1000000)) negative is the creation time. Interstingly, this helped the model a lot to achieve a better match with the data. Now, regarding the base level of a specific chunk type, I am not aware of a command in ACT-R that can do it, but certainly it is possible write a function like this yourself. Can you tell use why would you want to do it?

That corresponds basically to what I saw when testing the ACT-R tutorial models. Depending on the model/experiment they would all run, but there were very few trials which could run without exhausting the heap for most of them. The limited heap that they give is fairly restrictive (at least with respect to ACT-R) and just loading the full ACT-R 5 consumes quite a bit of things. One could go in and hand tool the ACT-R so as to excise anything you didn't need and perhaps tweak some things here and there in terms of space requirements. However, overall I doubt it's worth the effort because you're still probably going to hit that limit fairly quickly. That leaves you with basically one option - get a "complete" Lisp system. Since you said you're using Linux you've got several options. The most expensive would be to buy a version of Allegro Common Lisp from Franz Inc.. You could also buy the full version of LispWorks, which is cheaper than ACL, but may still be too much. The cheapest option would be to get a copy of CMUCL or CLisp because they're free. CMUCL works fine with ACT-R (and the ACT-R Environment now) and there are several other people using that combination who may be willing to help. CLisp is very fast, but there are a few known problems with using it with ACT-R and it does not work with the ACT-R Environment at this point. I don't know how many users are actually using CLisp with ACT-R, so you may not find much in the way of help either, but I really just don't know there. Hope that helps, and sorry I don't have an easier solution for you.

Submission Deadline: May 3, 2004 Location: Washington, DC. URL: http://xenia.media.mit.edu/~nlc/conferences/fss04.html Description: Although there has been substantial progress in some of the subfields of artificial intelligence during the past three decades, the field overall is moving toward increasing subfield isolation and increasing attention to near-term applications, retarding progress toward comprehensive theories and deep scientific understanding, and ultimately, retarding progress toward developing the science needed for higher-impact applications. Recent work in artificial intelligence, in addition to cognitive psychology, neuroscience, and linguistics, presents an opportunity to reverse this specialization and reinvigorate the field's focus on understanding and developing human-level intelligence. Because there are so few venues for research on integration and because the opportunity is so great, we propose to gather researchers working across the boundaries of their subfields to explore new computational techniques and research methodologies for integrating research results to produce more intelligent systems. We plan to address three broad topics of interest. First, what can models of vision, language, learning, and reasoning in fields such as cognitive psychology, linguistics and neuroscience contribute to artificial intelligence? Is there a way to describe and organize these results so that they can be more easily shared and combined across subfields? Second, how can we integrate multiple perception, action, representation, learning, planning, and reasoning systems to build cognitive models and intelligent systems that significantly advance the level of intelligence we can model or achieve? Is there a way to characterize the strengths and weaknesses of each approach and determine when to use each? Finally, what kind of theoretical, methodological, or technological innovations are needed to accelerate this research? Will it require advances in cognitive modeling, cross-domain and inter-subfield ontologies, or some kind of institutional transformation? The topics of interest lead us to encourage a wide range of presentations, including presentations focused on the integration and interconnection of multiple systems, on the contributions of fields such as cognitive psychology, neuroscience, and linguistics to integration questions, and on methodological issues having to do with integration.
