I notice with growing frustration that nobody is out there trying to coordinate simulation events. From the last newsletter, I learned that there will be held: April 1-5: AI and Simulation (New Orleans, Louisiana) while there was previously announced: April 1-2: AI and Simulation in Planning of High Autonomy Systems (Cocoa Beach, Florida) >From the last Simulation Journal, I learned that SCS organizes their next Summer Computer Simulation Conference: July 22-24: SCSC (Baltimore, Maryland) while IMACS announced their three-annual world congress to take place: July 22-24: IMACS Congress (Dublin, Ireland) Obviously, these conflicts are hurting the potential attendance of all events. This is pure nonsense, and I wish to protest loudly against such mismanagement! Francois Cellier, Ph.D. Associate Professor Dept. of Electr. & Comp. Engr.

Myers" <rmyers@ICS.UCI.EDU> X-Organization: UC Irvine Department of ICS X-Original-Path: ucivax!orion.oac.uci.edu!ucsd!sdd.hp.com!uakari.primate.wisc.edu!uflorida!simulation Date: Wed, 10 Oct 90 19:09:46 -0700 From: Richard Myers <rmyers@ICS.UCI.EDU> I am looking for information on simulation packages that can be used to model neural networks from the bottom up and possibly using anatomical data. We now use a modified version of the Rochester Connectionist Simulator (RCS). An ideal replacement would have the following attributes: OBJECT ORIENTED - Models should be implemented using an object oriented paradigm. For example, a model of a "brain" would be composed of many "neuron" objects that each contain their own state and connectivity data but share the same functionality. This would help in building bottom up models because low level objects such as "neurons" could be debugged separately before you assemble a "brain". EVENT DRIVEN - The sequence of events in the simulator should be dynamically generated and scheduled by the objects being modeled. For example, object B causes object C to change only if object A causes a change in object B that exceedes a certain threshold. The alternative would be to pass control to all three objects in order and have each object check if it should change based on the results of its predecessor. PSEUDO TIME - Objects should be able to schedule the order of events with some notion of real time. Imagine the previous example but with a "delay" before control passes to object C. Control would pass to other objects before object C changes. I believe this is a common feature of data network simulators in which the delay caused by a signal propagating down a wire is important. We would also like a system with a graphical user interface that allows for easy monitoring of events and probing of objects. A revision control system and an experiment control system would also be nice. :-) POSSIBLE SOLUTIONS GENESIS comes very close to what we want but it lacks a true object oriented (ala small-talk) approach to creating models. Communication between objects also appears pretty limited and predefined. BONES might work but I haven't heard of anyone successfully modeling neural networks with it. I have heard that BONES has a nice revision control and experiment control system though. RCS isn't object oriented, event driven or have any concept of time delays. I welcome any changes or extensions to the above specification or any comments or alternatives to my analysis of possible solutions. I realize that I'm asking for the moon, but hopefully this will generate some discussion on what is available and what is needed for neural network simulation. Thank you for your time, -- Richard ------------------------------------------------------------------------------- "Programs were devised whose `thinking' was to human thinking as a slinky flipping end over end down a staircase is to human locomotion." -- D.R.

This is a call for abstracts, approximately fifteen of which will be selected for development and presentation at the Conference. All papers, and a number of selected abstracts, will be published in Proceedings, available late 1991. Abstracts should be between 600 and 1000 words, and are due by December 1, 1990. Submission of an abstract indicates the submitter's intention and capability to write and present the corresponding, full length paper, if chosen. Participation in the Conference is limited to 140 people in the following categories: 1. Participants who have been invited to present papers based on their abstracts. (Limit 15) 2. Participants who have submitted abstracts judged by the Program Committee to be of particular interest. (Limit 35) 3. Participants with creative and clearly stated interests in the topic who are involved with work on cyberspace in any capacity. (Limit 60) 4. Visitors & observers, who are not actively working in the field at this time but who have expressed interest in the subject. (Limit 30) As with the First Conference at Austin in 1990, the Second International Conference on Cyberspace is not primarily about the enabling technology of VR, 3-D interfaces or high speed computer graphics. Its focus is on the nature of cyberspace conceived of as an independent realm, a shared virtual environment whose inhabitants, objects and spaces are data, but data which is visualized, heard and (perhaps) touched. Effective technical means of access to, and navigation in, cyberspace is assumed. The focus of the Conference is theoretical and conceptual. The Second Conference will continue the project, begun at the First Conference in Austin, of attempting to arrive at the outlines of a consensus and vision of cyberspace as a workable system. It also seeks to reach an understanding of how the components of cyberspace already "under construction" in the development and design of graphic user interfaces, scientific visualization techniques, video games, CAD, abstract architecture and architectural design theory, knowledge navigation, "cyberpunk" discourse, cultural studies, film and narrative theory, virtual and artificial reality systems, ISDN and other networks, groupware, and hypermedia might someday function together to create a true, public cyberspace, as well as private, special-purpose cyberspaces: viable, 3-dimensional, alternate realities providing the maximum number of individuals with the means of communication, creativity, productivity, mobility, and control over the shapes of their lives within the new information and media environment. The Second International Conference on Cyberspace is scheduled to take place in six sessions over two days and two nights. The sessions, outlined below, follow along the lines of the First Conference. I. WHY CYBERSPACE? Representative subtopics: the nature/ validity/lessons of William Gibson's vision; cyberspace and mythology; the nature of work and power in an "informated" society (cf. Zuboff); cyberspace as the site of multinational/ multilocational business; the role of cyberspace in corporate life and the corporation in cyberspace; implosion and media; global vs. local vs. private systems; costs and benefits of reifying information; the directions and futures of computing; cyberspace entertainment or work, addiction or production; McLuhan revisited: global village or global dream. . . II. LOGICAL AND ONTOLOGICAL PROBLEMS. Representative subtopics: space-time axiomatics; magic vs. logic; the presence of self and others; the meaning of travel and action; what does nature mean in a technological environment (cf. Dagognet); the framing of cyberspace; strategies of search and navigation; requisite levels of structure and consensus; dealing with subjectivity in virtual space; body as metaphor of coding (cf. Haraway); rethinking clothing, body surface, prosthesis; what to do when your best friend is a construct. . . III. CYBERSPACE, POWER, AND CULTURE: ROUNDTABLE DISCUSSION. Politics of representation in cyberspace; implications for minority discourse; implications of teleagency; what counts as style, and why; interactive virtual theater (cf. Laurel); discussion of legal, economic, and technological factors in the institution of cyberspace(s); the meaning of surveillance, security, privacy, and control in cyberspace; the disabled/differently abled in cyberspace; governments, institutions, corporations, individuals: who owns/ creates/manages cyberspace(s)?; who is excluded and who is likely to exclude themselves from cyberspace; who becomes invisible because of cyberspace; whither responsibility?; cops and robbers, or: what is crime in a virtual world?; who pays, who profits?; whose vision is cyberspace anyway. . . IV. REPRESENTING AND MANIPULATING DATA IN SPACE. Natural vs. artificial coordinate systems; the form and meaning of data objects; state, phase, and abstract spaces of scientific visualization; 3-dimensional user interface design; ambiguity, complexity and learning; visual languages; art and science together at last?; real world control and feedback; human performance with abstract stimuli. . . V. VISUALIZATIONS OF THE SYSTEM. Literary, graphic, or computer examples of, attempts at, and designs for cyberspace, at the public or private scale; architecture in, and the architecture of, cyberspace; alternative spatiotemporal metaphors from "physical reality"; computational models for large communication and data networks. . . VII. DINNER AND WRAP UP. Summary, discussion, and setting of date and place of the Third International Conference on Cyberspace. LOCATION. The Conference will take place on the campus of the University of California at Santa Cruz, overlooking Monterey Bay approximately 70 miles south of San Francisco. UCSC has a well-deserved reputation as one of the world's most beautiful universities. ACCOMMODATIONS. Rates range upward from $70 per night, although slightly lower rates may be unearthed by the perspicacious. The Conference has reserved a block of rooms at a somewhat reduced rate in the Santa Cruz Holiday Inn. The Conference office is coordinating reservations and information will be supplied in the registration packet. There are several attractive bed-and-breakfast establishments in the area. The Registration Packet contains information about other hotels, B&Bs, etc. The Group for the Study of Virtual Systems will attempt to provide affordable lodging for a limited number of student attendees and others who demonstrate financial need. The UC Santa Cruz campus is not within easy walking distance of lodging. However, there is frequent bus service to and from the campus, and there are plans for a Conference jitney. TRANSPORTATION. Closest airports are San Jose International and Monterey. San Francisco and Oakland International airports are roughly 70 miles from Santa Cruz. There is frequent bus and limousine service to and from San Jose. RECREATION (or quasi-recreation). The proximity of Silicon Valley may permit Conference attendees to make some on-site visits to Valley companies. Details will be announced later. For those wishing a more kinesthetic experience than current cyberspace implementations afford, Santa Cruz possesses a world-famous rollercoaster. The Monterey Aquarium and several world-class amusement parks are nearby. Elephant seals will be mating in their spectacular fashion at the Ano Nuevo National Wildlife Refuge. Big Sur National Seashore is just to the south. And although March may not be quite warm enough for swimming, Santa Cruz' sunny beaches are fine for relaxing. BUSINESS DEADLINES. Deadline for submission of abstracts is December 1, 1990. Notification of selection for presentation by December 30, 1990. Deadline for registration is January 15, 1990. REGISTRATION. Cost of registration includes printed material, two lunches, and final dinner (Session VI). Registration for participants is $180.00, which includes copies of the Collected Abstracts and preferred seating; registration for visitors and observers is $100.00, and includes the Collected Abstracts and one lunch. SCHOLARSHIPS. A limited number of registrations and accommodations will be made available at reduced rate to students and others demonstrating financial need. CORRESPONDENCE.
