Anomaly Detection

open access: yesComputers, Materials & Continua, 2009
The paper presents a revolutionary framework for the modeling, detection, characterization, identification, and machine-learning of anomalous behavior in observed phenomena arising from a large class of unknown and uncertain dynamical systems. An evolved behavior would in general be very difficult to correct unless the specific anomalous event that ...

Video anomaly detection using Cross U-Net and cascade sliding window

open access: yesJournal of King Saud University: Computer and Information Sciences, 2022
As video surveillance exponentially increases, a method that automatically detects abnormal events in video surveillance is essential. Several anomaly detection methods have been proposed to detect abnormal events in video surveillance. Much research has

Multi-Perspective Anomaly Detection [PDF]

open access: yesSensors, 2021
Anomaly detection is a critical problem in the manufacturing industry. In many applications, images of objects to be analyzed are captured from multiple perspectives which can be exploited to improve the robustness of anomaly detection. In this work, we build upon the deep support vector data description algorithm and address multi-perspective anomaly ...

An Improved Composite Hypothesis Test for Markov Models with Applications in Network Anomaly Detection [PDF]

open access: yes, 2015
Recent work has proposed the use of a composite hypothesis Hoeffding test for statistical anomaly detection. Setting an appropriate threshold for the test given a desired false alarm probability involves approximating the false alarm probability. To that
