Abductive Reasoning with Uncertainty
Audun Jřsang
Abductive reasoning in general describes
the process of discovering hypotheses and
rules that would entail a given conclusion.
Abductive reasoning consists of assessing
the likelihood that a specific hypothesis entails
a given conclusion. Abductive reasoning
based on probabilities is used in many
disciplines, such as medical diagnostics,
where medical test results combined with
conditional probabilities are used to determine
the likelihood of possible diseases. In
this paper we focus on abductive reasoning
in subjective logic. The advantage of
our approach over a purely probabilistic approach
is that degrees of ignorance can be
explicitly included as input and during the
analysis.
