Information theory for data-driven risk analysis: The informational coefficient of correlation as a measure of dependency

Publikation: Bidrag til bog/antologi/rapport/proceedingKonferencebidrag i proceedingsForskningpeer review

In this paper uncertainty quantification and structural reliability analysis are reinterpreted through the information theory. At first, main concepts of information theory are presented, e.g. Entropy, KL Divergence, Mutual Information (MI); their relationships with the classical uncertainty quantification, like maximum likelihood estimation and copulas are discussed. Moreover, the Distributions with Independent Components (DIC), recently proposed by the authors for uncertainty quantification, are based on the mutual information. Herein, it is questioned the adoption of the linear coefficient of correlation to measure the dependence between random variables. An alternative measure, called informational coefficient of correlation and based on the mutual information is suggested. Some examples show the robustness of the proposed informational coefficient of correlation, which can be used also as a metric for global sensitivity analysis.
