From Wolfgang.Schoppek at uni-bayreuth.de Tue Feb 10 07:40:53 1998 From: Wolfgang.Schoppek at uni-bayreuth.de (Wolfgang Schoppek) Date: Tue, 10 Feb 1998 13:40:53 +0100 Subject: modelling knowledge about causal relations Message-ID: <34E04AD5.FC28EE57@uni-bayreuth.de> In my efforts of modelling the acquisition of causal knowledge I encountered the following problem: Suppose there is an input-variable affecting several output-variables. The goal is to create chunks which represent these effects. For every successive state of the problem a new chunk is created which holds the values of the variables. By comparing the last two states the effects (of the input) can be induced. And this is my question: can a production match information in any slot of a lhs-chunk (performing an OR-operation like "if the value of output1 = 1 or the value of output2 = 1")? Can anybody help me with that question, or has anybody experience/problems in modelling the acquisition of causal knowledge in ACT-R? -- Wolfgang -------------------------------------------------------------------- Dr. Wolfgang Schoppek <<< Tel.: +49 921 555003 <<< Lehrstuhl fuer Psychologie, Universitaet Bayreuth, 95440 Bayreuth http://www.uni-bayreuth.de/departments/psychologie/wolfgang.htm -------------------------------------------------------------------- From cl+ at andrew.cmu.edu Thu Feb 12 16:44:53 1998 From: cl+ at andrew.cmu.edu (Christian J Lebiere) Date: Thu, 12 Feb 1998 16:44:53 -0500 (EST) Subject: Fifth Annual ACT-R Summer School and Workshop Message-ID: FIFTH ANNUAL ACT-R SUMMER SCHOOL AND WORKSHOP ============================================= Carnegie Mellon University - July 1998 ====================================== ACT-R is a cognitive theory and simulation system for developing cognitive models for tasks that vary from simple reaction time to air traffic control. Each year, a summer school and workshop are held to train researchers in the use of the system and to enable current users to exchange results and ideas. The fifth Annual ACT-R Summer School and Workshop will be held at Carnegie Mellon University in Pittsburgh from July 6 to 21, 1998. Each summer school and workshop participant will receive a complimentary copy of The Atomic Components of Thought, the new book to be published next summer describing the latest developments of the ACT theory. The summer school will take place from Monday July 6 to Friday July 17, with the intervening weekend free. This intensive 10-day course is designed to train researchers in the use of ACT-R for cognitive modeling. It is structured as a set of 8 units, with each unit lasting a day and involving a morning theory lecture, a web-based tutorial, an afternoon discussion session and a homework assignment which students are expected to complete during the day and evening. The final two days of the summer school will be devoted to individual research projects. Computing facilities for the tutorials, assignments and research projects are provided. Due to space limitations, admission is limited to a dozen participants, who must submit by APRIL 1 an application consisting of a curriculum vitae and statement of purpose. Applications will be strengthened if the applicants include a description of a data set that they want to model at the summer school. If students are accepted to the summer school but do not bring a data set, they must be prepared to work with other students on their data sets. Successful student projects will be presented at the workshop, which all summer school students are encouraged to attend. Applicants will be notified of admission by APRIL 15. A stipend of up to $750 is available for graduate students. To qualify for the stipend, students must be US citizens and join to their application a letter of reference from a faculty member. Admission to the summer school is free. The workshop will take place from the morning of Saturday July 18 to Tuesday July 21 at noon. Mornings will be devoted to research presentations, each lasting 30 minutes including questions. Participants are invited to present their ACT-R research by submitting a presentation title and a short abstract. Afternoons will feature discussion sessions and instructional tutorials. Suggestions for the topics of the discussion sessions are welcome. Evenings will be occupied by demonstration sessions, during which participants can gain a more detailed knowledge of the models presented and engage in unstructured discussions. Admission to the workshop is open to all and the registration fee is $100. A registration form is appended below.
