Representing Bayesian Networks Within Probabilistic Horn Abduction

نویسنده

  • David Poole
چکیده

This paper presents a simple framework for Horn­ clause abduction, with probabilities associated with hypotheses. It is shown how this representation can represent any probabilistic knowledge representable in a Bayesian belief network. The main contributions are in finding a relationship between logical and prob­ abilistic notions of evidential reasoning. This can be used as a basis for a new way to implement Bayesian Networks that allows for approximations to the value of the posterior probabilities, and also points to a way that Bayesian networks can be extended beyond a propositional language.

From Probabilistic Horn Logic to Chain Logic

Probabilistic logics have attracted a great deal of attention during the past few years. Where logical languages have, already from the inception of the field of artificial intelligence, taken a central position in research on knowledge representation and automated reasoning, probabilistic graphical models with their associated probabilistic basis have taken up in recent years a similar positio...

Probability Propagation Nets

This work introduces a Petri net representation for the propagation of probabilities and likelihoods, which can be applied to probabilistic Horn abduction, fault trees, and Bayesian networks. These so-called “probability propagation nets” increase the transparency of propagation processes by integrating structural and dynamical aspects into one homogeneous representation. It is shown by means o...

A Viterbi-like algorithm and EM learning for statistical abduction

We propose statistical abduction as a rstorder logical framework for representing and learning probabilistic knowledge. It combines logical abduction with a parameterized distribution over abducibles. We show that probability computation, a Viterbilike algorithm and EM learning for statistical abduction achieve the same eÆciency as specilzed algorithms for HMMs (hidden Markov models), PCFGs (pr...

Representing Diagnostic Knowledge for Probabilistic Horn Abduction

This paper presents a simple logical framework for abduction, with probabilities associated with hypotheses. The language is an extension to pure Prolog, and it has straight-forward implementations using branch and bound search with either logic-programming technology or ATMS technology. The main focus of this paper is arguing for a form of representational adequacy of this very simple system f...
