Log anomaly detection benchmarks sensitive to evaluation protocols, study finds

By PulseAugur Editorial · [1 sources] ·

A new research paper explores how different evaluation protocols can significantly alter the conclusions drawn from log anomaly detection benchmarks. The study, conducted on HDFS and BGL logs, investigates the impact of split construction, data representation visibility, and component costs. Findings indicate that random splits can lead to inflated scores, while chronological evaluation on BGL logs reveals different performance orderings. The research also quantifies the cost of different pipeline stages, separating parsing and representation expenses from classifier training and prediction. AI

IMPACT Highlights the importance of standardized evaluation protocols in AI research to ensure reproducible and comparable results.

    Protocol-Sensitive Evaluation of Log Anomaly Detection: Component Costs and Target-Access Sensitivity on HDFS and BGL

    Protocol choices can change the conclusions drawn from log anomaly detection benchmarks even when detector settings are fixed. We present a joint empirical study of split construction, representation visibility, and component costs using six fixed count, sequence, and semantic co…
