Quantifying Statistical Significance of Deep Nearest Neighbor Anomaly Detection via Selective Inference

In real-world applications, anomaly detection (AD) often operates without access to anomalous data, necessitating semi-supervised methods that rely solely on normal data. Among these methods, deep $k$-nearest neighbor (deep $k$NN) AD stands out for its interpretability and flexibility, leveraging di…
