Charles River Analytics Presents Research on Situation Awareness at AIAA Infotech@Aerospace

Charles River Analytics, a developer of cutting-edge technologies for intelligent systems, presented research on situation awareness (SA) at the American Institute of Aeronautics and Astronautics Infotech @Aerospace conference that took place from April 20-22, 2010, in Atlanta, Georgia.

Dr. Avi Pfeffer, Senior Scientist at Charles River, presented his research on Probabilistic Relational Models (PRMs) in the session, “Probabilistic Relational Models for Situational Awareness.” PRMs are an object-oriented representation that model the world in terms of objects and relationships between them; they also allow uncertainty over the relational structure to be expressed.

Mr. Joe Gorman, Principal Software Engineer at Charles River, presented “Probabilistic Evidential Reasoning with Symbolic Argumentation for Space Situation Awareness,” which he co-wrote with Dr. Glenn Takata, Senior Software Engineer. Mr. Gorman’s presentation described “an approach, based on Toulmin’s theory of argumentation, which provides an intuitive representation that can be used to create and exercise models of space situations. These models are then supplied to a fusion component that uses the Dempster-Shafer theory of belief propagation to estimate confidences for the characterization of these situations of interest.”
