METHOD FOR CONSTRUCTING NETWORK FAULT HANDLING MODEL, FAULT HANDLING METHOD AND SYSTEM

摘要

The present invention relates to the technical field of communications. Disclosed are a method for constructing a network fault handling model, a fault handling method and a system. The method for constructing a network fault handling model comprises: obtaining or establishing a deep neural network model of a source domain on the basis of a sample set of the source domain in a network; establishing a sample set of a target domain in the network, the sample sets of the target domain and of the source domain having an intersection, and both including quantified alarm data, fault data and configuration data; and if the coincidence rate of the sample sets of the target domain and of the source domain reaches a set threshold, constructing a network fault handling model of the target domain on the basis of the deep neural network model of the source domain. In the present invention, the network fault handling model of the target domain is obtained by means of cross-domain transfer learning on the basis of the deep neural network model of the source domain in an optical network.
