LogMILP: Weakly-Supervised Log Anomaly Localization via Counterfactual Perturbation

ai-technology · 2026-05-13

Researchers propose LogMILP, a weakly supervised framework for log anomaly detection and localization. The method uses multi-instance learning with prototype-guided structural modeling and counterfactual perturbation consistency regularization. It requires only bag-level labels to perform both bag-level detection and instance-level localization. Experiments on three public datasets show competitive performance.
