6. The method of claim 1 , the graphical models associated with the null distribution datasets represented as a bi-partite graph includes a first row of nodes and a second row of nodes, the first row of nodes connected to the second row of nodes by zero or more arcs.
1. A machine implemented method that determines a number of non-spurious arcs associated with a learned graphical model, comprising: retrieving datasets and learning algorithms; applying the learning algorithms against the datasets to generate the learned graphical model; generating null distribution datasets based at least in part on retrieved datasets; employing the learning algorithms and the null distribution dataset to generate graphical models associated with the null distribution datasets; determining an average number of arcs associated with the graphical models associated with the null distribution datasets; enumerating a total number of arcs associated with the learned graphical model; and disseminating the average number of arcs and the total number of arcs, the average number of arcs provides a numerator value.
