Publication number: 20230185202Abstract: An apparatus and method of diagnosing an unobserved operational parameter of a machine or apparatus. The method including obtaining a plurality of causal relationships between pairs of parameters of the machine or apparatus, wherein each pair includes a cause parameter and an effect parameter. For at least some of the parameters, a decomposition of the parameters into a plurality of information components is determined, based on the determined causal relationships between the parameters. The decomposition includes a synergistic information component including information obtained from a combination of at least two causal relationships having the parameter as effect parameter. A parameter is determined to include a negative synergistic information component. Based on the existence of the negative synergistic information component, it is diagnosed that an unobserved operational parameter provides a cause for the parameter including the negative synergistic information component.Type: ApplicationFiled: April 9, 2021Publication date: June 15, 2023Inventor: David Evert Song Kook SIGTERMANS
