Using Learning Features to Find Similar Trajectories
In the last decade,the trajectories data have been collected by many applications and such trajectories contain rich information that can be used to detect events especially for anomaly event detections.However,there are still many challenges on this problem,the major one is how to identify the similar trajectories on semantic level.In this work,we extract the nature features from raw trajectories and use them to do the semantic trajectory similarity search.To achieve this,we propose a PLS algorithm to detect such semantic similar trajectories efficiently and effectively.We also leverage the DBSCAN to help extract the information from large trajectory data.The results of our algorithm are demonstrated by the real world dataset.
