In order to perform efficient inference, graphical transformations of these networks are performed. The complexity of inference is proportional to the total table size of tables corresponding to the cliques of the triangulated graph. Therefore in order to get efficient inference it is desirable to have small cliques in the triangulated graph. We analyze existing heuristic triangulation methods applicable to BN2O networks after transformations using parent divorcing and tensor rank-one decomposition and suggest several modifications. Both theoretical and experimental results confirm that tensor rank-one decomposition yields better results than parent divorcing in randomly generated BN2O networks that we tested.</abstract> <abstract language="cze" primary="0">Síť typu BN2O je Bayesovská síť se strukturou bipartitního grafu, ve kterém jsou všechny hrany orientované z jedné části (horní vrstva) do druhé části (dolní vrstva) a ve kterém jsou všechny pravděpodobnostní tabulky noisy-or. Pro zvýšení efektivnosti inference jsou tyto sítě transformovány z hlediska jejich grafové struktury. Složitost inference je úměrná celkové velikosti tabulek v síti. Proto je cílem transformace dosáhnout co nejmenší součet velikosti tabulek triangulované sítě. Článek testuje existující metody triangulace aplikovatelné na sítě BN2O po transformacích parent divorcing a tensor rank-one decomposition a navrhuje některé modifikace. Jak teoretické, tak experimentální výsledky potvrzují, že tensor rank-one decomposition poskytuje lepší výsledky než parent divorcing na náhodně generovaných sítích BN2O, které byly v experimentu použity.</abstract>  <action target="WRD"> <ARLID>cav_un_auth*0252448</ARLID> <name>ECSQARU 2009.
