Similarity representation plays a central role in increasingly popular anomaly detection techniques, which have been successfully applied in various realistic scenes. Until now …
Anomaly detection in videos refers to identifying events that rarely or shouldn't happen in a certain context. Among all existing methods, the idea of reconstruction or future frame …
We consider the problem of anomaly detection with a small set of partially labeled anomaly examples and a large-scale unlabeled dataset. This is a common scenario in many …
Anomaly detection is an important problem that has been researched within diverse research areas and application domains. Many anomaly detection techniques have been …

Anomaly detection presents a unique challenge in machine learning, due to the scarcity of labeled anomaly data. Recent work attempts to mitigate such problems by augmenting …
We address a critical yet largely unsolved anomaly detection problem, in which we aim to learn detection models from a small set of partially labeled anomalies and a large-scale …
