A two-phase online anomaly detection method based on support vector clustering (SVC) in the presence of non-stationary data is developed in this paper which permits arbitrary-shaped data clusters to be precisely treated. In the first step, offline learning is performed to achieve an appropriate detection model. Then the current model dynamically evolves to(More)
An online clustering method based on a time-varying quadratic programming is proposed which can precisely detect streaming data clustering structure when no assumption is desired on the shape and density of data classes. In the proposed method, online clustering is achieved through simulating some dynamical equations which yield optimum solution of the(More)
