This paper presents the I-map hybrid algorithm for selecting , given a data sample, a linear Gaussian model whose structure is a directed graph. The algorithm performs a local search for a model that meets the following criteria: (1) The Markov blankets in the model should be consistent with dependency information from statistical tests. (2) Minimize the… (More)
A Bayes net has qualitative and quantitative aspects: The qualitative aspect is its graphical structure that corresponds to correlations among the variables in the Bayes net. The quantitative aspects are the net parameters. This paper develops a hybrid criterion for learning Bayes net structures that is based on both aspects. We combine model selection… (More)
This paper describes the design, implementation and check up of a non-trivial Ada&reg; program involving tasking and generic packages in the context of an evaluation of the VAX Ada compiler and Ada Programming System Environment. The exercise took place at the end of 1985 at the European Laboratory for Particle Physics (CERN).
