Trajectory representation learning plays a pivotal role in supporting various downstream tasks, such as travel time estimation, trajectory classification and Top-k similar search. Traditional methods order to filter the noise GPS trajectories tend focus on routing-based simplify trajectories. However, these approaches ignore motion details contained data, limiting capability of learning. To fill this gap, we propose novel framework that is Jointly G PS Route Modeling based self-supervised...

Stay area detection is one of the most important applications in trajectory data mining, which helpful to understand human's behavior intentions. Traditional stay methods are based on GPS with relatively high sampling rate. However, because privacy issues, accessing can be difficult real-world applications. Fortunately, traffic surveillance cameras have been widely deployed urban area, and it provides us a novel way acquiring vehicles' trajectories. All vehicles that traverse by recognized...

The feasibility of especial technology which complex cavity aluminum alloy castings are formed by corroding pre-burying copper pipe core is discussed researching on the size and microstructure core. results indicate basically consistent with original castings, a dimensional tolerance in permission scope about 0.01mm. Meanwhile, wall identical that without corrosion. Moreover, because equal to chilled iron, bringing cold effect, crystal grain tinier. Therefore, using form casting entirely feasible.
