Omniview-Tuning: Boosting Viewpoint Invariance of Vision-Language Pre-training Models

no code implementations18 Apr 2024 Shouwei Ruan, Yinpeng Dong, Hanqing Liu, Yao Huang, Hang Su, Xingxing Wei

Vision-Language Pre-training (VLP) models like CLIP have achieved remarkable success in computer vision and particularly demonstrated superior robustness to distribution shifts of 2D images.

Enriched Physics-informed Neural Networks for Dynamic Poisson-Nernst-Planck Systems

no code implementations1 Feb 2024 Xujia Huang, Fajie Wang, Benrong Zhang, Hanqing Liu

The resampling strategy is employed in the EPINNs to accelerate the convergence of loss function.

Surrogate-assisted cooperative signal optimization for large-scale traffic networks

no code implementations3 Mar 2021 Yongsheng Liang, Zhigang Ren, Lin Wang, Hanqing Liu, Wenhao Du

The decomposition operation significantly narrows the search space of the whole traffic network, and the surrogate-assisted optimizer greatly lowers the computational burden by reducing the number of expensive traffic simulations.

A Surrogate-Assisted Variable Grouping Algorithm for General Large Scale Global Optimization Problems

no code implementations19 Jan 2021 An Chen, Zhigang Ren, Muyi Wang, Yongsheng Liang, Hanqing Liu, Wenhao Du

SVG first designs a general-separability-oriented detection criterion according to whether the optimum of a variable changes with other variables.
