Rethinking Weak Supervision in Anomaly Detection: A Comprehensive Benchmark
Researchers introduce WSADBench, the first unified benchmark for weakly supervised anomaly detection (WSAD) that evaluates 36 algorithms across 4 modalities and over 700K experiments. The study reveals that specialized WSAD methods only outperform in extreme label-scarcity scenarios, while general foundation models and classification approaches dominate with increased supervision, fundamentally challenging current research isolation.
