DynGL-SDP: Dynamic Graph Learning for Semantic Dependency Parsing

1 code implementation COLING 2022 Bin Li, Miao Gao, Yunlong Fan, Yikemaiti Sataer, Zhiqiang Gao, Yaocheng Gui

A recent success in semantic dependency parsing shows that graph neural networks can make significant accuracy improvements, owing to its powerful ability in learning expressive graph representations.

Disturbance Rejection-Guarded Learning for Vibration Suppression of Two-Inertia Systems

no code implementations16 Apr 2024 Fan Zhang, Jinfeng Chen, Yu Hu, Zhiqiang Gao, Ge Lv, Qin Lin

On the other hand, machine learning benefits from an additional assurance layer provided by the ESO, as any imperfections in the machine learning model can be compensated for by the ESO.

Robust Control Barrier Functions for Safe Control Under Uncertainty Using Extended State Observer and Output Measurement

no code implementations26 Aug 2023 Jinfeng Chen, Zhiqiang Gao, Qin Lin

Our approach provides a less conservative estimation error bound than other disturbance observer-based CBFs.

A General Model-Based Extended State Observer with Built-In Zero Dynamics

no code implementations25 Aug 2022 Jinfeng Chen, Zhiqiang Gao, Yu Hu, Sally Shao

A general model-based extended state observer (GMB-ESO) is proposed for single-input single-output linear time-invariant systems with a given state space model, where the total disturbance, a lump sum of model uncertainties and external disturbances, is defined as an extended state in the same manner as in the original formulation of ESO.

CDNet: Centripetal Direction Network for Nuclear Instance Segmentation

1 code implementation ICCV 2021 Hongliang He, Zhongyi Huang, Yao Ding, Guoli Song, Lin Wang, Qian Ren, Pengxu Wei, Zhiqiang Gao, Jie Chen

Specifically, we define the centripetal direction feature as a class of adjacent directions pointing to the nuclear center to represent the spatial relationship between pixels within the nucleus.

Gradient Distribution Alignment Certificates Better Adversarial Domain Adaptation

1 code implementation ICCV 2021 Zhiqiang Gao, Shufei Zhang, Kaizhu Huang, Qiufeng Wang, Chaoliang Zhong

In particular, we show that the distribution discrepancy can be reduced by constraining feature gradients of two domains to have similar distributions.
