Electronic apparatus for clustering graph data on basis of gnn and control method therefor

An electronic apparatus comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the electronic apparatus to:
• obtain, based on log data of a plurality of devices, a first graph comprising first information regarding a plurality of devices and second information regarding relevance among the plurality of devices;
• obtain an edge-based second graph based on the first graph such that a second plurality of edges of the second graph comprise a first plurality of edges of the first graph, and the second plurality of edges comprise third information regarding a plurality of clustering rules from the first plurality of edges of the first graph;
• convert the second graph into a node-based third graph such that a third plurality of nodes of the third graph comprise the third information;
• convert the third information from the third plurality of nodes into a plurality of probability labels of the third plurality of nodes, wherein a probability label indicates relevance between two devices from among the plurality of devices;
• convert the third graph into an edge-based fourth graph such that a fourth plurality of edges of the fourth graph comprise the plurality of probability labels from the third plurality of nodes;
• and
• cluster the plurality of devices into a plurality of groups based on the first graph and the fourth graph.
