Outlier Detection Based on the Damped Model in Mixed Data Streams
|
Abstract:
Outlier detection in data streams poses great challenges due to the limited memory availability and real time detection requirement.A fast outlier detection algorithm in mixed data streams was introduced by clustering the data streams incrementally based on the damped model and generating the cluster features on behalf of the data distribution.The radius threshold value changed dynamically.When detection requirement was received the outlier factor of specified clusters was calculated and the clusters with h...
