Diffusion Counterfactual-Based Anomaly Detection in Class-Imbalanced Data
ICASSP 2025accepted
Anomaly detection suffers from data imbalance, as anomalies are typically rare. Due to the smaller number of anomaly samples, models may overfit the features of the normal samples, resulting in poor performance when detecting anomalies. Historically, this issue has typically been addressed by unders…
