Abstract: A method of managing system health is provided. The method includes calculating a reconstruction missing value with respect to the second domain data, determining a degree of degradation of the system on the basis of the reconstruction missing value, predicting a second remaining useful life (RUL) prediction value {tilde over (y)} of the system on the basis of the second domain data, based on a result of the determination of the degree of degradation, optimizing a degradation compensation function on the basis of a distribution of a first RUL prediction value y of the system predicted based on the first domain data in a pre-learning process of the diagnosis model, and predicting a final RUL prediction value {tilde over (y)}′ obtained by compensating for the second RUL prediction value {tilde over (y)}, by using the optimized degradation compensation function.

Abstract: Provided is a method of extracting a mediator variable and a mediation influence from a multivariate set. The method includes: receiving a database in which a set of N multiple variables (N is a natural number) including at least one of discrete time series data or continuous time series data is stored; selecting a test variable set including an independent variable, a dependent variable, and a mediator variable from the database in which the multivariate set is stored; determining the mediator variable using transfer entropy and conditional transfer entropy for the selected test variable set; and calculating a mediation influence of the determined mediator variable, wherein the mediation influence is separately calculated as an individual causal influence of the mediator variable and a group causal influence of mediator variables.
