GLOSSARY

Agent-based modeling: An adaptive modeling method that simulates the behaviors of individuals to generate data for the analysis of the behaviors of groups

Bayesian networks: A probabilistic graphical model that represents the functional dependencies between a collection of variables of interest

Biometrics: Automated methods of analysis of physical or behavior characteristics for the purpose of identification

Blue forces: A common term referring to “friendly” personnel in an area where conflict is occurring

Data fusion: The formal synthesis of many distinct types of information (audio, visual, written, etc.) to support decision making

Decision theory: A sub-discipline of both game theory and statistics, this is the determination of optimal actions in the presence of uncertainty, when the consequences of those actions are known and depend on various unknown states of nature, which are addressed through the use of probabilistic modeling

Game theory: The study of optimal decision-making in situations that involve a number of players, stipulating either competitive or cooperative interactions between the players, in which their individual payoffs are a function of both their actions and those of the other players, and that involve states of nature which may be only incompletely known

Green forces: A common term referring to the civilians in an area where conflict is occurring

IED: Improvised explosive device

IRA: Provisional Irish Republican Army

JDLR: “Just doesn’t look right”

Market-sentiment data: An analysis method used to assess the attitude of a group of consumers

Mixed-initiative decision making: A cyclical method of data training where a user guides a computer program during analysis with the aim of teaching the program how to perform the analysis with greater accuracy Network tomography: The field of inferential network monitoring, in which internal characteristics of a network are inferred by using information derived from end-point data Pashtun: The Pashto-speaking people who constitute the majority of the population in Afghanistan Principal-component analysis: A method used on a set of variables that identifies the primary linear combinations of those variables which account for the majority of the variance in the full set of variables. Its goal is to reduce the dimensionality of a complex data set with many related variables Probabalistic neural networks: A non-linear statistical model used to fit a response whose structure derives from a model of how information can be combined through the use of a collection of independent sensory nodes Red forces: A common term referring to the personnel of adversaries in an area where conflict is occurring Viral marketing: A system of marketing that uses pre-existing social networks to spread a marketing message by encouraging recipients to pass on information Wiki: A collection of web pages that allows all users to contribute and modify data 69
