Hypergame analysis introducing certainty factor
1997 IEEE International Conference on Systems, Man, and Cybernetics. Computational Cybernetics and Simulation, 2002The paper presents two methods of hypergame analysis to model and analyze such conflicts where players have plural perceptions about conflict situations. A certainty factor is first defined to evaluate the assurance degree for expected game. The certainty factor is fundamental and is used to combine plural perceptions in hypergame. The relation between

From certainty factors to belief networks
Artificial Intelligence in Medicine, 1992The certainty-factor (CF) model is a commonly used method for managing uncertainty in rule-based systems. We review the history and mechanics of the CF model, and delineate precisely its theoretical and practical limitations. In addition, we examine the belief network, a representation that is similar to the CF model but that is grounded firmly in ...

Inductive certainty factors from databases
Proceedings of the Twenty-Eighth Hawaii International Conference on System Sciences, vol.3, 2002Efficient use of intelligent information systems requires tools that can assist not only in finding information that can be deduced from the databases, but also in inferring missing information using similarity and statistical based measures adapted from artificial intelligence.

Bayes’ formulas are complex enough and definitely not adequate to human’s brain reasoning activities. Certainty factors theory is an alternative to Bayesian reasoning – when reliable statistical information is not available or the independence of evidence cannot be assumed – and introduces a certainty factors calculus based on the human expert ...

In this chapter we will discuss an approach to reasoning under uncertainty, the certainty factor (CF) formalism, which was intended for use with rule-based Expert Systems. It has been criticised on a number of grounds, as we shall see. However, it is an interesting example of a heuristic approach which attempts to weaken some of the axioms of ...

Disease Diagnosis System Using Certainty Factor
2019 International Conference on Electrical, Electronics and Information Engineering (ICEEIE), 2019The use of traditional medicine has been growing rapidly lately. One of the medicinal plants that have been developed especially in East Kalimantan is Dayak onion plant (Eleutherinepalmifolia (L.) Merr). Dayak onion concoctions have also been used by various groups of Dayaks as an alternative medicine for various diseases, and also to find out the ...
