Document Type and Number:
WIPO Patent Application WO/2024/034024
Kind Code:
A1
Abstract:
A causal model construction device according to one aspect of the present disclosure comprises a collection unit configured to acquire network topology information representing the network topology of an ICT system for which an abnormal location is to be estimated, and a model construction unit configured to use the network topology information to construct a causal model for estimating the abnormal location from observation data at a time when an abnormality has occurred in the ICT system.
