This abstract first appeared for US patent application 18691865 titled 'SYSTEMS AND METHODS FOR PERFORMING ROOT CAUSE ANALYSIS
Original Abstract Submitted
A method for root cause analysis in a network comprising a set of nodes Ni for i=1 to N, where N>2. The method includes obtaining N sets of KPI data, each one of the N sets of KPI data being for one of the N nodes. The method also includes, for each one of the N nodes, using the set of KPI data associated with the node to generate feature vectors for the node. The method also includes generating relationship data using the feature vectors, the generated relationship data, indicating relationships between the nodes within the set of N nodes. The method also includes inputting to a GNN the generated relationship data and the feature vectors. The method also includes obtaining from the GNN information indicating that at least node Nj is a candidate root cause node and at least node Nk is a candidate victim node, where k≠j. The method further includes using the relationship data to i) determine whether to indicate the candidate root cause node Nj as a predicted root cause node and/or ii) determine whether to indicate the candidate victim node Nk as a predicted victim node.
