New regularization technique tackles anomaly detection collapse

Researchers have identified a phenomenon called "convergence collapse" in certain anomaly detection models. This occurs when models trained to minimize squared-error loss become less effective at detecting anomalies as they improve. The issue stems from the model learning to track the target even for anomalous data, thus eliminating the residual signal. To address this, the paper proposes Kernel-Anchored Locality Regularization (KAR), which constrains the model's predictions by penalizing deviations from a kernel-weighted average of training targets. This method aims to prevent collapse and enhance anomaly detection capabilities. AI
