Latent Space Subdivision: Stable and Controllable Time Predictions for Fluid Flow [article]

Steffen Wiewel, Byungsoo Kim, Vinicius C. Azevedo, Barbara Solenthaler, Nils Thuerey
2020 arXiv   pre-print
We focus on single-phase smoke simulations in 2D and 3D based on the incompressible Navier-Stokes (NS) equations, which are relevant for a wide range of practical problems.  ...  In addition, we highlight the benefits of a recurrent training on the latent space creation, which is performed by the spatial compression network.  ...  Source code and video: https://ge.in.tum.de/publications/ latent-space-subdivision/.  ...

Overlooked Poses Actually Make Sense: Distilling Privileged Knowledge for Human Motion Prediction [article]

Xiaoning Sun, Qiongjie Cui, Huaijiang Sun, Bin Li, Weiqing Li, Jianfeng Lu
2022 arXiv   pre-print
Previous works on human motion prediction follow the pattern of building a mapping relation between the sequence observed and the one to be predicted.  ...  This simulator takes as input the observed sequence, but approximates the behavior of Priv-Encoder, enabling FP-Network to imitate the interpolation process.  ...  STS-GCN [43] realizes cross-talk of space and time within only one graph, and is able to factorize the graph into separable space and time matrices for better understanding of both features.  ...
