4 Session 3: Bayesian Network
4.1 내용정리
Introduction
- “A Bayesian network consists of a graphical structure and a probabilistic descrip- tion of the relationships among variables in a system. The graphical structure explic- itly represents cause-and-effect assumptions that allow a complex causal chain linking actions to outcomes to be factored into an articulated series of conditional relationships” (Borsuk, Stow, & Reckhow., 2004, p. 219).
- Because of these links between actions and outcomes, social scientists can generate predictive results and develop network structure among variables beyond traditional social scientific approaches to increase the power of analysis. Conditional independence is at the core of Bayesian networks (Pe’er, 2005).
- For the current example, we will look at situations where a number of people are working together in a complex environment. A number of these situations like Military training or Firefighting are potentially dangerous and costly. The develop- ment of new technology such as games provides us an opportunity to train people in a safer environment. Because of technological development, we can make these training simulations very close to real world actions. We use the term multiteam system (MTS) to describe nested teams engaged in military or firefighting opera- tions.
