Reasoning about uncertain contexts in pervasive computing environments
2004
IEEE pervasive computing
Preserved Fulltext
A prototype pervasive computing infrastructure, Gaia, allows applications and services to reason about uncertainty using mechanisms such as probabilistic logic, fuzzy logic, and Bayesian networks. ...
Our model represents any piece of information whose truth value is potentially uncertain as a predicate. ...
Reasoning about uncertainty has helped make components in our pervasive computing environment more robust and more capable of adapting to changing dynamics. ...
