Comparing Expert Systems Built Using Different Uncertain Inference Systems

no code implementations27 Mar 2013 David S. Vaughan, Bruce M. Perrin, Robert M. Yadrick

This study compares the inherent intuitiveness or usability of the most prominent methods for managing uncertainty in expert systems, including those of EMYCIN, PROSPECTOR, Dempster-Shafer theory, fuzzy set theory, simplified probability theory (assuming marginal independence), and linear regression using probability estimates.

The Role of Tuning Uncertain Inference Systems

no code implementations27 Mar 2013 Ben P. Wise, Bruce M. Perrin, David S. Vaughan, Robert M. Yadrick

This study examined the effects of "tuning" the parameters of the incremental function of MYCIN, the independent function of PROSPECTOR, a probability model that assumes independence, and a simple additive linear equation.

An Odds Ratio Based Inference Engine

no code implementations27 Mar 2013 David S. Vaughan, Bruce M. Perrin, Robert M. Yadrick, Peter D. Holden, Karl G. Kempf

Expert systems applications that involve uncertain inference can be represented by a multidimensional contingency table.
