From r.m.young at acm.org Tue Mar 1 13:31:23 2005 From: r.m.young at acm.org (Richard M Young) Date: Tue, 1 Mar 2005 18:31:23 +0000 Subject: [ACT-R-users] advice/practice about setting base-level for familiar items Message-ID: Hello Acters, I'd like to ask about advice and "good practice" (or failing that, "common practice" or even just "practice") about setting the base-level activation for familiar items, such as frequently used words. For example, say in my case a chunk which links my written name "Richard" with the concept (or "meaning") RICHARD, is very familiar to me, I've encountered it frequently and recently and therefore its base-level activation (BLA) should be high, much higher than say an item that I've encountered just once, several seconds ago. It will therefore be retrieved much faster, so to get realistic latencies from an Act-R model it is important to set the BLAs at least roughly right. Furthermore, the BLA of a long-familiar item should not decay measurably during the performance of a task. Q1. I don't really have a quantitative feel for the BLAs. Should it be around say 5.0 in a case like that, does anybody know? I'm not sure how to set it appropriately, and the means for doing so interact with whether base-level learning is on or not, and with whether optimised learning is on or not. One can use the command (set-base-level ...) to set the BLA directly, but only if :bll is off. (And incidentally, turning :bll on later seems to cause problems for Act.) If :bll is on, then the command (set-base-level ...) has to be used with frequency and recency parameters. For example, I've found that specifying an N of 10000 with a time of -20000 gives a BLA of around 5.0. Q2. What sort of numbers do other modellers use for a familiar item of this kind? However ... if one turns optimised learning off, either before the (set-base-level ...) command or after it, Act-R gets hung up and, at least for those numbers I've used, runs out of memory (!). Q3. So, what is a sensible BLA for a familiar chunk, and how does one set it if one wants to run the model with optimised learning off for the items that are learned during the course of the model run?

Systems Engineer for Human Error Modeling for Error Tolerant Systems (HEMETS) Small Business Innovative Research project HEMETS The interaction of humans with computers in environments which are increasingly information rich and demand fast decision time yields errors when human capabilities and limitations are not designed into a system. These "human errors" can lead to serious and even deadly consequences, such as friendly-fire incidents during combat. If knowledge of the cause of human errors resulting from a particular design were available to the system designers before implementing a system, then the design could be modified or an alternative design chosen to reduce or remove these errors, or at least enable recovery from the errors. One method to provide such knowledge is the development of software which can both simulate human performance given a system design and predict the errors likely to occur from this design. In order to develop such a tool, D.N. American is undertaking the development of a computational Human Error Modeling tool for Error Tolerant Systems (HEMETS). This is an extension of previous work in which we successfully designed the Human Error Modeling Architecture (HEMA) which provides the core component of HEMETS. HEMA is built upon ACT-R and, utilizing an analysis of research in human errors, established a cognitive architecture for human error modeling. HEMETS will utilize HEMA to assess a wide variety of designs. There are a number of challenges to develop a functional HEMETS. Some of these are: 1. Extending ACT-R to incorporate the error modeling aspects needed to implement HEMA. 2. Developing an easily-used, reusable method to interface HEMETS to system simulations. 3. Tracking the activities of HEMA to determine the cause(s) of error resulting from a system design. 4. Developing an automated output which communicates the likely operator errors resulting from a system design and offers recommendations to improving the design. This work is funded under an Office of Naval Research (ONR) Small Business Innovative Research (SBIR) grant. Candidate Capabilities 1. Experience with LISP programming: either a minimum of 1 year on the job experience or graduate school experience which used LISP programming, preferably in modeling some aspect of human cognition or behavior. 2. B.S. Computer Science with experience, or M.S. /PhD. Computer or Cognitive Science. 3. Experience with ACT-R cognitive architecture; experience with other cognitive architectures will be considered. 4. Self-starter, independent worker capable of creative approaches. 5. Good communication skills, especially technical writing. Job Duties: 1. Develop detailed design of Human Error Modeling Architecture (HEMA) and HEMETS components. 2. Implement HEMA as extensions and additions to ACT-R. 3. Design human studies to validate HEMETS error predictions. 4. Work with consultant and PI to insure HEMA integrates with interface to system simulations. 5. Design an automated subsystem which both explains error cause due to a proposed system design and offers recommendations to eliminate or reduce those errors. 6. Develop technical papers and presentations for customer (ONR) and cognitive modeling community. This position gives an individual the opportunity to do post-doctoral type work with the pay and benefits of a thriving small company. There may be an opportunity for a graduate student to intern part-time with pay, but no company benefits. Application Applicants should email a resume to mike.fotta at dnamerican.com D.N.

The papers span information and signal processing theory, resource management, network protocols, and systems issues. Moreover, this year for the first time IPSN has an expanded scope in the form of the SPOTS track which focuses on platform, tools, and application issues. This makes IPSN a unique forum that brings together researchers from the conceptual and the practical ends of sensor networking. The conference opens each day with key note talks by well known international experts who collectively span theory vs. application, academe vs. industry, and US vs. non-US activities in sensor networking. The agenda includes oral sessions with 30 papers that address aspects of energy and network lifetime issues, novel programming paradigms, architectures for sensor data inference, modeling of real-life wireless and sensing artifacts, secure and verifiable localization of sensor nodes, information theoretic and signal processing considerations, sensor selection, networked sensor platforms, design and management tools, and applications. The 37 papers in the poster session cover a similar diversity of topics. The demonstration session has 27 exciting participants demonstrating new tools, platforms, applications, and practical realizations of new algorithms and protocols, and is significantly enhanced relative to previous years. In particular, this year we have instituted a Best Demo award to encourage and reward research efforts that seek to concretely realize theoretical ideas.

I am currently developing some C++ code that will be able to apply Markov Chain Monte Carlo (MCMC) methods to an ACT-R model with observed data and come up with posterior distributions of parameters and likely paths of action (ie production firing/chunk recall) for sub-populations or individuals based on data observed for these populations/individuals. Right now, my code is in the early stages: 1) I am still working with terminal or non-learning models 2) The code is restricted to models where either: a) all observable data for an individual is collected at the very end of a model run or, b) The observable data for each individual specifies the exact path of that individual (ie, progression of production firing and chunk recall) through the model. 3) The code cannot (yet) handle ACT-R perceptual-motor modules. 4) The code doesn't handle production compilation (ie production learning) or chunk merging. Basically, the code needs to know a priori all possible productions that could fire and all possible chunks that can be retrieved through any model run. I am looking for some (relatively) simple models that I could use to test the code out and possibly try to help answer some interesting research questions using these likelihood-based methods. If anyone knows of any models out there, or if anyone has a model they think would be appropriate and is willing to let me take a look at it, or has any questions, comments, or suggestions, please email me (address below).
