Learning Bayesian network parameters from small data sets: application of Noisy-OR gates
2001
International Journal of Approximate Reasoning
Preserved Fulltext
We test our method on HEPAR EPAR II II, a model for diagnosis of liver disorders, whose parameters are extracted from a real, small set of patient records. ...
Diagnostic accuracy of the multiple-disorder model enhanced with the Noisy-OR parameters was 6.7% better than the accuracy of the plain multiple-disorder model and 14.3% better than a single-disorder diagnosis ...
The HEPAR EPAR II I I model was created and tested using SMILE, an inference engine, and GeNIe, a development environment for reasoning in graphical probabilistic models, both developed at the Decision ...
