✦ Synopsis

We present the results of an application of Bayesian networks to the evaluation of the quality of roofing slate. Using data from borehole samples of a slate deposit, two networks constructed with different levels of expert knowledge input were evaluated for their capacities for inference and prediction of the quality of slate for roofing.

It can be concluded from the results that Bayesian networks are an extremely useful automated tool for evaluating the quality of a resource such as slate for the following reasons: they allow final quality to be assessed immediately and in probabilistic terms with a tolerable degree of uncertainty; they enable the probability of obtaining different final qualities to be estimated when new data is introduced into the network; they speed up the evaluation process by simulating and optimising the work of the expert (during field data collection and borehole description) in identifying the parameters with the greatest influence on final quality; and finally, they have a satisfactory capacity for prediction.

A Bayesian network consists of a directed acyclic graph (DAG) and a set of conditional probability distributions (CPDs); they together define a joint probability distribution (jpd). The structure of the DAG dictates how a jpd can be factorized as a product of CPDs. This CPD factorization view of Bay

If we wish to evaluate the efficacy of a proposed treatment applicable only to a subset of the patient population, then a comparison of the results of the proposed treatment with historical experience may be misleading if the applicability of the proposed treatment is itself of prognostic value. We
