Finding and Explaining Optimal Treatments

Influence diagrams are modern decision-theoretic representations that can be used to model medical decision-making problems. The output of evaluating an influence diagram are decision tables with optimal decision alternatives. For real-life clinical problems the resulting tables can be really big, so that understanding what they say is nearly impossible. KBM2L lists are new list-based structures suitable for minimising memory storage space of these tables, and at the same time searching for a better knowledge organisation. In this paper, we study the application of KBM2L lists for finding the optimal treatments for gastric non-Hodgkin lymphoma.
