Topology-aware self-supervised multivariate KPI anomaly detection and root cause node localization for network operations

Multivariate key performance indicator (KPI) streams collected in network operations contain rich evidence for anomaly diagnosis, but practical deployment remains difficult because fault labels are scarce, KPI dependencies are strong across time and metrics, and fault effects propagate through network topology. This pa...
