Uncertain inference using interval probability theory

James W. Hall, David I. Blockley, John P. Davis
1998 International Journal of Approximate Reasoning  
The use of interval probability theory (IPT) for uncertain inference is demonstrated. The general inference rule adopted is the theorem of total probability.  ...  Uncertain inference using IPT is compared with Bayesian inference.  ...  A review of interval probability theory IPT is founded on the axioms of probability theory but allows support for a conjecture to be separated from support for the negation of the conjecture.  ...

The method combines features of the theory of fuzzy sets, Shafer’s theory of evidence (Shafer 1976) and probability theory to form a suitable framework for uncertain logical rea- soning.  ...  Probability and fuzzy logic are examples of two such choices. The modeling of uncertain inference is, however, rather different from the traditional problems of modeling physical systems.  ... 

Uncertain deduction and conditional reasoning

Jonathan St. B. T. Evans, Valerie A. Thompson, David E. Over
2015 Frontiers in Psychology  
We argue that the study of "uncertain deduction" should directly ask people to assign probabilities to both premises and conclusions, and report an experiment using this method.  ...  Most every day and scientific inference is made from more or less confidently held beliefs and not assumptions, and the relevant normative standard is Bayesian probability theory.  ...  ofTable 3are derived using the total probability theorem of probability theory.  ...

PROBABILISTIC INFERENCE FOR INTERVAL PROBABILITIES IN DECISION-MAKING PROCESSES

Oļegs Uzhga-Rebrov, Galina Kuleshova
2019 Environment Technology Resources Proceedings of the International Scientific and Practical Conference  
The present paper considers one approach to Bayes' formula based probabilistic inference under interval values of relevant probabilities; the necessity of it is caused by the impossibility to obtain reliable  ...  For visualisation purposes, the state of initial and target information is modelled using probability trees.  ...  That interpretation underlies the theory of uncertain probabilities of P. Walley. The theory can be regarded as a specific extension of the traditional subjective probability theory.  ...

BAYESIAN NETWORK WITH INTERVAL PROBABILITY PARAMETERS

WEI-YI LIU, KUN YUE
2011 International journal on artificial intelligence tools  
Interval data are widely used in real applications to represent the values of quantities in uncertain situations.  ...  However, the implied probabilistic causal relationships among interval-valued variables with interval data cannot be represented and inferred by general Bayesian networks with point-based probability parameters  ...  As well, the rule-based methods, D-S evidence theory, fuzzy set and rough set theories are frequently used mechanisms for representing and inferring uncertain knowledge. 19 Among these methods, the D-S  ...

Foundations of probabilistic inference with uncertain evidence

Frank J. Groen, Ali Mosleh
2005 International Journal of Approximate Reasoning  
Uncertain evidence is defined as the class of observations for which this statement cannot take place in certain terms.  ...  It is a significant class of evidence, since it cannot be treated using Bayes Theorem in its conventional form [G. Shafer, A Math-  ...  Alternative theories, such as Fuzzy Logic [2] , Possibility Theory [3] and Evidence Theory [4] have been advocated as theories that should be used where Probability Theory allegedly fails to apply  ...
