This paper presents a new methodology for integrating expert knowledge, based on Monte Carlo simulations and which avoids the costly elicitation of these prior distributions and only requests from the expert information about those direct probabilistic relationships between variables which cannot be reliably discerned with the help of the data.
Abstract
Automatic learning of Bayesian networks from data is a challenging task, particularly when the data are scarce and the problem domain contains a high number of random variables. The introduction of expert knowledge is recognized as an excellent solution for reducing the inherent uncertainty of the models retrieved by automatic learning methods. Previous approaches to this problem based on Bayesian statistics introduce the expert knowledge by the elicitation of informative prior probability distributions of the graph structures. In this paper, we present a new methodology for integrating expert knowledge, based on Monte Carlo simulations and which avoids the costly elicitation of these prior distributions and only requests from the expert information about those direct probabilistic relationships between variables which cannot be reliably discerned with the help of the data.

Review: Bayesian networks in environmental modelling

TL;DR: The literature review indicates that BNs have barely been used for Environmental Science and their potential is, as yet, largely unexploited.

Decision support analysis for safety control in complex project environments based on Bayesian Networks

TL;DR: The safety control process is extended to the entire life cycle of risk-prone events in model application, rather than restricted to pre-accident control, but during-construction continuous and post-accidents control are included.

Bayesian Network Approach to Multinomial Parameter Learning using Data and Expert Judgments

TL;DR: A multinomial parameter learning method is presented, which can easily incorporate both expert judgments and data during the parameter learning process and achieves much greater learning accuracy with much less data.

Bayesian network modeling of accident investigation reports for aviation safety assessment

TL;DR: This paper analyze the historical passenger airline accidents that happened from 1982 to 2006 as reported in the National Transportation Safety Board (NTSB) aviation accident database using a four-step procedure to construct a Bayesian network to capture the causal relationships embedded in the sequences of these accidents.

An interactive approach for Bayesian network learning using domain/expert knowledge

TL;DR: The interactive approach for integrating domain/expert knowledge at different stages of the learning process of a Bayesian network: while learning the skeleton and when directing the edges of the directed acyclic graph structure.

Induction of Decision Trees

J. R. Quinlan
- 25 Mar 1986 - 
TL;DR: In this paper, an approach to synthesizing decision trees that has been used in a variety of systems, and it describes one such system, ID3, in detail, is described, and a reported shortcoming of the basic algorithm is discussed.

Causation, prediction, and search

TL;DR: The authors axiomatize the connection between causal structure and probabilistic independence, explore several varieties of causal indistinguishability, formulate a theory of manipulation, and develop asymptotically reliable procedures for searching over equivalence classes of causal models.

Learning Bayesian Networks: The Combination of Knowledge and Statistical Data

TL;DR: In this article, a Bayesian approach for learning Bayesian networks from a combination of prior knowledge and statistical data is presented, which is derived from a set of assumptions made previously as well as the assumption of likelihood equivalence, which says that data should not help to discriminate network structures that represent the same assertions of conditional independence.
