Modeling Human Reasoning About Meta-Information

Guarino1, S., Pfautz1, J., Cox1, Z., and Roth2, E. International Journal of Approximate Reasoning (2009) Information, as well as its qualifiers, or meta-information, forms the basis of human decision- making. Human behavior models (HBMs) therefore require the development of representations of both information and meta-information. However, while existing models and modeling approaches may include computational technologies […]

Assessing Novel Adaptive Displays Impact on Pilot Performance

Guarino1, S., Liu2, D., Roth3, E., Bartosiewicz2, M., Harper1, K. and Vincenzi, D.4 International Symposium of Aviation Psychology (2009) Combat aircraft advances have led to dramatic increase in the operational tempo facing the Navy pilot, increasing the likelihood for Situation Awareness (SA) failures, biases, and information overload. We designed a system for constructing intelligent adaptive displays to […]

Adaptive Boundary Aids in Complex Air Combat Scenarios

Guarino1, S., Liu2, D., Roth3, E., Harper1, K., and Vincenzi4, D. Proceedings of the Human Factors and Ergonomics Society Annual Meeting, (October, 2009) Advances in aircraft operational capabilities have led to a dramatic increase in the operational tempo facing air combat aviators, which has in turn led to SA failures, particularly with respect to secondary information. […]

Displays of Talker Location Improve Voice Identification Performance in Multitalker, Spatialized Audio Environments

Kilgore, R. Human Factors (2009) Whilespatialized audio is known to improve speech intelligibility and voice-identification accuracy within multitalker environments, prior studies have not found any additional benefit for augmenting spatialized audio with visual depictions of relative voice locations. These studies, however, were restricted to small audio environments (four voices), potentially limiting the ability of simple talker location […]

Enabling Robust C2 Systems through Evolvable Human-In-The-Loop Data Fusion

Mahoney1, S., Pfautz1, J., Roth2, E., Powell3, G., Fichtl1, T., Guarino1, S., Carlson1, E., and Farry1, M. Proc. of the International Command and Control Research and Technology Symposium (ICCRTS) (2009) Data fusion systems are being increasingly used to support military planning, decision making, and command and control functions in general. Typically, these systems are designed around […]

Automated Rapid Training of ATR Algorithms

McBride1, J., Lowell1, J., Snorrason1, M., Eaton2, R., and Irvine3, J. Proceedings of SPIE Defense, Security & Sensing, Automatic Target Recognition XIX, vol. 7335, Orlando, FL (2009) Computer vision methods, such as automatic target recognition (ATR) techniques, have the potential to improve the accuracy of military systems for weapon deployment and targeting, resulting in greater […]

Enabling Operator/Analyst Trust in Complex Human Socio-Cultural Behavior Models

Pfautz, J., Carlson, E., Farry, M., and Koelle, D. Proceedings from the Human Behavior-Computational Modeling and Interoperability Conference (2009) Predictive models of human socio-cultural behavior (HSCB) are often developed to aid decision makers by providing insight into current situations and the potential consequences of alternative courses of action. However, in many cases the operational users—the intended […]

User-Created and User-Adaptable Technosocial Modeling Methods

Pfautz1, J., Carlson1, E., Koelle1, D., and Roth2, E. Technosocial Predictive Analytics: Papers from the 2009 AAAI Spring Symposium (2009) Over the course of our studies of how intelligence analysis professionals perform their work, we have observed that the perceived utility of technosocial models varies with the degree that analysts could create and/or adapt a model […]

Complexities and Challenges in the Use of Bayesian Belief Networks: Informing the Design of Causal Influence Models

Pfautz1, J., Koelle1, D., and Carlson1, E., and Roth, E.2 Proceedings from the Human Factors and Ergonomics Society 53rd Annual Meeting Bayesian belief networks (BNs) are well-suited to capturing vague and uncertain knowledge. However, the capture of this knowledge and associated reasoning from human domain experts often requires specialized knowledge engineers responsible for translating the […]

CTPPL: A Continuous Time Probabilistic Programming Language

Pfeffer, A. Proceedings of the Twenty-First International Joint Conference on Artificial Intelligence (IJCAI-09) (2009) Probabilistic programming languages allow a modeler to build probabilistic models using complex data structures with all the power of a programming language. We present CTPPL, an expressive probabilistic programming language for dynamic processes that models processes using continuous time. Time is a […]

Figaro: An Object-Oriented Probabilistic Programming Language

Pfeffer, A. Charles River Analytics Technical Report (2009) We introduce an object-oriented paradigm for probabilistic programming, embodied in the Figaro language. Models in Figaro are objects, and may have properties such as conditions, constraints, and relationships to other objects. Figaro can represent a wide variety of probabilistic models, including directed and undirected first-order models such as […]

Using Reasoning Patterns to Help Humans Solve Complex Games

Pfeffer, A., and Antos, D. Proceedings of the Twenty-First International Joint Conference on Artificial Intelligence (IJCAI-09) (2009) We propose a novel method for helping humans make good decisions in complex games, for which common equilibrium solutions may be too difficult to compute or not relevant. Our method leverages and augments humans’ natural use of arguments in […]
