Researchers have developed a novel non-parametric method for conditional anomaly detection, utilizing soft harmonic functions to identify unusual data instances or class labels. This approach estimates label confidence to detect anomalous mislabeling and includes regularization to prevent the identification of isolated examples or those on the distribution's boundary. The method's effectiveness has been demonstrated on synthetic, UCI ML, and real-world electronic health record datasets for identifying unusual patient management decisions. AI
