The proposed method conducts global variance-based sensitivity analysis on Bayesian networks by treating multiple parameters as uncertain at once. This approach assesses the importance of these inputs jointly using low-rank tensor decomposition to prevent the curse of dimensionality. The resulting network is then analyzed using Sobol’s method, which provides global sensitivity indices that can differ significantly from one-at-a-time (OAT) analysis. The authors demonstrate this method on a benchmark array of both expert-elicited and learned Bayesian networks.

This paper proposes a new way to analyze how changing different inputs affects the results of a complex model called a Bayesian network. Instead of looking at each input separately, it looks at all the inputs together to see how they work together. This approach helps us understand which inputs are most important and how they interact with each other.
