Method and system for processing at least one set of alarms emitted in a communication network

Abstract

Method and system for processing at least one set of alarms emitted in a communication network. The invention relates to a method for processing at least one set of alarms emitted in a communication network, each alarm comprising at least one attribute data distinct from a temporal data point. The method comprises, for each set of alarms, a so-called "classification" phase including steps implemented by a trained machine learning model, referred to as the "AI model," including: - determination (S10), for each alarm and by an encoding module of the AI ​​model, of a first vector representation encoding said at least one attribute data point; - determination (S20), from the first vector representations and by a transformer-encoder of the AI ​​model, of at least one output data point; - determination (S30), from said at least one output data point and by a classification head of the AI ​​model.of a classification result of said alarm set.

Claims

a third vector representation, said third vector representations being representative of a similarity of the alarms of said single set of alarms.

9. Method according to claim 8, said method further comprising a step of grouping (S40_C) the alarms of said single set of alarms into clusters from said third vector representations.

10. A method according to claim 6 or claim 7 in its dependence on claim 6 or claim 9, said method further comprising: - when the method conforms to claim 6 or to claim 7 in its dependence on claim 6, once the correction phase is completed and for each updated cluster, a step of determining an alarm belonging to said cluster and corresponding to an event in the communication network that caused the other alarms of said cluster to be emitted; or - when the method conforms to claim 9, once the grouping step is completed and for each cluster, a step of determining an alarm corresponding to an event in the communication network that caused the alarms of said cluster to be emitted.

11. A method according to any one of claims 1 to 10, wherein the communication network is an optical communication network or a CAN-type network deployed in a transport vehicle.

12. Computer program comprising instructions for carrying out a processing method according to any one of claims 1 to 11 when said program is executed by a computer.

13. Computer-readable recording medium on which a computer program according to claim 12 is recorded.

14. A device for processing at least one set of alarm messages emitted in a communication network, referred to as an "alarm set", each alarm message comprising at least one piece of information characteristic of the alarm associated with said alarm message, said processing device comprising means configured to implement a processing method according to any one of claims 1 to 11.
