Outlier Detection of Network-Constrained Uncertain Trajectories

摘要：

The trajectories outlier detection algorithm has received more and more many attentions, while outlier detection of Network-constrained uncertain trajectories is a new research direction. Since trajectories data is usually inherent uncertainty and large in size, the trajectories anomaly detection algorithm must address uncertainty and improve storage efficient. Using sketch technology to compress uncertain data size and reducing the number of adjacent sections to improve efficient, an outlier detection algorithm is proposed in this paper. The experimental results show that the proposed algorithm can improve the efficiency of the algorithm and reduce the waste of storage space.
