Subject: [ACT-R-users] Goal Stack
In-Reply-To: <CAHZ4p4GTBa_eNxa2N6SY-p1akjYfJ6QRuv83NdTg6_smQ_3Cmw@mail.gmail.com>
Message-ID: <D0D9712F.19D63%troy.d.kelley6.civ@mail.mil>

All,

Could someone out there remind me of the reasoning for getting rid of the
goal stack? 

We have been using a goal stack with SS-RICS and have found it to be useful
for handling task interruptions.  So the stack is flexible and
interruptible.  

If I remember correctly there was some question as to how the goal stack can
have perfect recall, so that if one goal is popped, the next goal is
automatically retrieved with no decay.

We have solved this by having activation associated with goals, so that
goals decay while they are on the stack.  This means that the goal might not
be perfectly recalled to the goal stack once the previous goal is retrieved.
This also duplicates the strange behavior of  - "walking into a room and not
knowing why you are there".  Because the goal of going to a room to find
some object has decayed while you were going to the room.

Any ideas on this?

There may be better references out there, but the first three talks from
the 1999 ACT-R Workshop address this issue:

<http://act-r.psy.cmu.edu/?post_type=workshops&p=7369>

Basically, an infinitely deep perfect memory (the goal stack) is
not plausible, but using the existing declarative memory activation
mechanisms to retrieve past goals instead works well.

Hope that helps,
Dan

*Twenty-Second Annual ACT-R Workshop*


The Twenty-Second Annual ACT-R workshop will take place from Friday July 17
to Sunday July 19, 2015 at Carnegie Mellon University. As in past years,
the workshop will consist of symposia, tutorial and talk sessions.
Participants are invited to present their ACT-R research by submitting a
one-page abstract with their registration. Suggestions for the topics of
the tutorials and symposia are requested.  Friday afternoon will feature a
presentation by an invited speaker.



This year, the theme of the workshop is *Scaling Up*.  While we have
achieved tremendous success developing limited-capacity, task-specific
models, the ultimate goal of generating models capable of broad,
human-level, task-general capabilities still largely eludes us.  The ACT-R
community has explored numerous approaches to achieve that goal, including
instruction following, theories of learning and transfer (e.g., PRIM, IBL),
model composition and generalization (e.g., supermodels), high-level
modeling languages (e.g., Herbal, HLSR), and integration with other
cognitive systems (e.g., robotics).  The central goal of the workshop is to
better understand the reasons underlying the challenges that we are facing
and the relations between the various approaches aimed at addressing them,
and outline a roadmap to potential long-term solution(s).  While we welcome
presentations on all topics relevant to ACT-R, please specify in your
submission if your presentation is related to this theme and if so how.
Also feel free to propose tutorials and suggest specific symposia topics
related to the workshop theme.



Admission to the workshop is open to all.  The early registration fee
(before June 1) is $100 and the late registration fee (after June 1) is
$125.  Informal proceedings of past workshops can be found on the ACT-R web
site (http://act-r.psy.cmu.edu/workshops/). Requests for presentations
should be submitted before *June 1* to receive full consideration for
inclusion in the workshop program.  A preliminary program of presentations
will be made available in early July.  Housing is available on a limited
basis in the CMU dormitories for the duration of the workshop at the rate
of about $60/day for single rooms and $40/day for double rooms.

 Registration information will be available at a later date.  Inquiries can
be sent to cl at cmu.edu.

 health behaviors using smartphones
Message-ID: <0C0BF411-5D89-43D7-844B-FEB7EC32AE75@parc.com>



I have Summer Internship position at PARC for a graduate student in psychology or computer science who is interested in modeling how people acquire new healthy habits from interactions with a smartphone application (Fittle) that we are actively researching. The ideal candidate will be a grad student in psychology or computer science who has developed computational cognitive models (ACT-R preferably).

We are just starting to develop an integrated model based on ACT-R. The goal is to have this model be capable of probabilistic predictions of individual behavior change with fine-grained parameters associated with contexts of everyday life (as measured through the smartphone and possibly devices such as FitBit), and the health goals, attitudes, beliefs, knowledge, etc. of the individuals themselves, and AI-based coaching interventions. The cognitive model is expected to drive further development of a user model and intelligent coaching agent in Fittle. One way to think of this is as the next generation of intelligent tutoring system: intelligent coaching in the ecology of everyday life.

You can find out more about this project at:

https://blogs.parc.com/blog/author/peterpirolli/

and then there is a bit more about the Fittle  app itself (from a somewhat marketing bent) at

http://www.fittle.org<http://www.fittle.org/>


If you are interested, please send me an email along with a CV.

Title: A Choice Prediction Competition for Decisions under Risk and Ambiguity

Dear colleagues and friends,

I write to invite you to participate in a choice prediction competition that Eyal Ert, Ori Plonsky and I organize.  The goal of this competition is to facilitate the derivation of models that can capture the classical choice anomalies (including Allais, St. Petersburg, and Ellsberg paradoxes, and loss aversion) and provide useful forecasts of decisions under risk and ambiguity (with and without feedback).

The rules of the competition are described in http://departments.agri.huji.ac.il/cpc2015.  The submission deadline is May17, 2015.  The prize for the winners is an invitation to be a co-author of the paper that summarizes the competition (the first part can be downloaded from http://departments.agri.huji.ac.il/economics/teachers/ert_eyal/CPC2015.pdf).

Here is a summary of the basic idea.  We ran two experiments (replication and estimation studies, both are described in the site), and plan to run a third one (a target study) during March 2015.  To participate in the competition you should email us (to eyal.ert at mail.huji.ac.il<mailto:eyal.ert at mail.huji.ac.il>) a computer program that predicts the results of the target study.

The replication study replicated 14 well-known choice anomalies. The subjects faced each of 30 problems for 25 trials, received feedback after the 6th trial, and were paid for a randomly selected choice. The estimation study examined 60 problems randomly drawn from a space of problems from which the replication problems were derived.  Our analysis of these 90 problems (see http://departments.agri.huji.ac.il/cpc2015) shows that the classical anomalies are robust, and that the popular descriptive models (e.g., prospect theory) cannot capture all the phenomena with one set of parameters. We present one model (a baseline model) that can capture all the results, and challenge you to propose a better model.  The models will be compared based on their ability to predict the results of the new target experiment. You are encouraged to use the results of the replication and estimation studies to calibrate your model.  The winner will be the acceptable model (see criteria details in the site) that provides the most accurate predictions (lowest mean squared deviation between the predicted choice rates and the choice rates observed in the target study).

Best, ido

Message-ID: <ABF19F00C84EBA86355C3720@actr6b.cmu.edu>

2015 ACT-R Summer School and Master Class
Carnegie Mellon University
July 13-16, 2015


ACT-R is a cognitive architecture, and it is realized in a software system
which can be used to develop cognitive models.  It has been used for modeling
tasks that range from experimental tasks like simple reaction time and list
learning, to real world tasks like driving a car and air traffic control.

The 2015 ACT-R Summer School will take place from July 13-16, just before the
22nd annual ACT-R Workshop which will also be held at Carnegie Mellon
University.  The Summer School will follow a format similar to that used in
ACT-R Spring Schools held at the University of Groningen and consist of both
a Summer School and a Master Class.

The Summer School will train researchers in the use of ACT-R for cognitive
modeling using the ACT-R tutorial.  The tutorial consists of eight units,
six of which will be covered during the four days of the Summer School.  Each
day will consist of a morning theory lecture covering one or two tutorial
units, an afternoon discussion session on the topics of the day, and modeling
assignments which participants are expected to complete during the day and
evening.

The Master Class is organized in parallel with the Summer School.  The Master
Class offers the opportunity for ACT-R modelers to work on their own projects
with guidance from experienced ACT-R researchers.  There is no curriculum for
the Master Class, but Master Class students are welcome to attend the Summer
School lectures and discussion sessions.

To provide an optimal learning environment, admission to the Summer School
and Master Class will be limited.  To apply for the Summer School, please
email a curriculum vitae and a statement of purpose to db30 at andrew.cmu.edu.
Demonstrated experience with a modeling formalism similar to ACT-R will
strengthen a Summer School application.  To apply for the Master Class please
email a curriculum vitae along with some information about your level of
experience with ACT-R and some details on the project you expect to work on
during the Master Class.


Applications are due by April 13th and applicants will be notified of
admission by April 30.

Admission to the Summer School and Master Class is free.  In addition, the
registration fee for the ACT-R Workshop will be waived for Summer School
Students, but not for students of the Master Class.  Housing will be
available in the CMU dormitories for approximately $60/day (single) or
$40/day (shared), and will be available through the end of the workshop.


More information about ACT-R, including papers published by the ACT-R
community, can be found on the ACT-R web site: <http://act-r.psy.cmu.edu/>.
For more information on the Summer School and Master Class you can email
Dan Bothell at db30 at andrew.cmu.edu.
