Domain Generalization for Vision-based Driving Trajectory Generation

1 code implementation22 Sep 2021 Yunkai Wang, Dongkun Zhang, Yuxiang Cui, Zexi Chen, Wei Jing, Junbo Chen, Rong Xiong, Yue Wang

In this paper, we propose a domain generalization method for vision-based driving trajectory generation for autonomous vehicles in urban environments, which can be seen as a solution to extend the Invariant Risk Minimization (IRM) method in complex problems.

Imitation Learning of Hierarchical Driving Model: from Continuous Intention to Continuous Trajectory

2 code implementations20 Oct 2020 Yunkai Wang, Dongkun Zhang, Jingke Wang, Zexi Chen, Yue Wang, Rong Xiong

One of the challenges to reduce the gap between the machine and the human level driving is how to endow the system with the learning capacity to deal with the coupled complexity of environments, intentions, and dynamics.

Learning hierarchical behavior and motion planning for autonomous driving

1 code implementation8 May 2020 Jingke Wang, Yue Wang, Dongkun Zhang, Yezhou Yang, Rong Xiong

To improve the tactical decision-making for learning-based driving solution, we introduce hierarchical behavior and motion planning (HBMP) to explicitly model the behavior in learning-based solution.

PPINN: Parareal Physics-Informed Neural Network for time-dependent PDEs

no code implementations23 Sep 2019 Xuhui Meng, Zhen Li, Dongkun Zhang, George Em. Karniadakis

Consequently, compared to the original PINN approach, the proposed PPINN approach may achieve a significant speedup for long-time integration of PDEs, assuming that the CG solver is fast and can provide reasonable predictions of the solution, hence aiding the PPINN solution to converge in just a few iterations.

Learning in Modal Space: Solving Time-Dependent Stochastic PDEs Using Physics-Informed Neural Networks

no code implementations3 May 2019 Dongkun Zhang, Ling Guo, George Em. Karniadakis

One of the open problems in scientific computing is the long-time integration of nonlinear stochastic partial differential equations (SPDEs).

Physics-Informed Generative Adversarial Networks for Stochastic Differential Equations

no code implementations5 Nov 2018 Liu Yang, Dongkun Zhang, George Em. Karniadakis

We developed a new class of physics-informed generative adversarial networks (PI-GANs) to solve in a unified manner forward, inverse and mixed stochastic problems based on a limited number of scattered measurements.

Quantifying total uncertainty in physics-informed neural networks for solving forward and inverse stochastic problems

no code implementations21 Sep 2018 Dongkun Zhang, Lu Lu, Ling Guo, George Em. Karniadakis

Here, we propose a new method with the objective of endowing the DNN with uncertainty quantification for both sources of uncertainty, i. e., the parametric uncertainty and the approximation uncertainty.
