Modeling trajectory data is a building block for many smart-mobility initiatives. Existing approaches apply shallow models such as Markov chain and inverse reinforcement learning to model trajectories, which cannot capture the long-term dependencies. On other hand, deep Recurrent Neural Network (RNN) have demonstrated their strength of modeling variable length sequences. However, directly adopting RNN trajectories not appropriate because unique topological constraints faced by trajectories....

4D medical image interpolation is essential for improving temporal resolution and diagnostic precision in clinical applications. Previous works ignore the problem of distribution shifts, resulting poor generalization under different distribution. A natural solution would be to adapt model a new test distribution, but this cannot done if input comes without ground truth label. In paper, we propose novel time training framework which uses self-supervision requiring any labels. Indeed, before...
