Classification: CPC H  G | IPC H

Claim 9:
10. A fault root cause identification apparatus, comprising:
at least one processor;
one or more memories coupled to the at least one processor and storing instructions for execution by the at least one processor, the instructions instruct the at least one processor to cause the apparatus to:
determine, from a plurality of first success flows based on a first failure flow in a first network, a first target success flow related to the first failure flow, wherein there is a similarity between the first target success flow and the first failure flow met a first preset condition; and
determine a target fault root cause of the first failure flow based on feature indicators of the first failure flow, feature indicators of the first target success flow, and a trained first machine learning model;
determine a plurality of second failure flows in a second network and a first known fault root cause corresponding to each of the second failure flows;
determine, from a plurality of second success flows in the second network, a second target success flow related to each of the second failure flows, wherein there is a similarity between each of the second failure flows and the second target success flow related to the second failure flow if a second preset condition is met; and
obtain the first machine learning model by performing training based on feature indicators of the plurality of second failure flows, the first known fault root cause corresponding to each of the second failure flows, and feature indicators of the second target success flow related to each of the second failure flows.
