CPFD: Confidence-aware Privileged Feature Distillation for Short Video Classification

no code implementations3 Oct 2024 Jinghao Shi, Xiang Shen, Kaili Zhao, Xuedong Wang, Vera Wen, Zixuan Wang, Yifan Wu, Zhixin Zhang

To integrate both features while maintaining efficiency and manageable resource costs, we present Confidence-aware Privileged Feature Distillation (CPFD), which empowers features of an end-to-end multi-modal model by adaptively distilling privileged features during training.

Multi-task deep learning for large-scale building detail extraction from high-resolution satellite imagery

1 code implementation29 Oct 2023 Zhen Qian, Min Chen, Zhuo Sun, Fan Zhang, Qingsong Xu, Jinzhao Guo, Zhiwei Xie, Zhixin Zhang

Understanding urban dynamics and promoting sustainable development requires comprehensive insights about buildings.

Asymptotical Cooperative Cruise Fault Tolerant Control for Multiple High-speed Trains with State Constraints

no code implementations4 Nov 2022 Zhixin Zhang, Zhiyong Chen

Based on the estimated values of states and faults, a distributed fault tolerance controller is designed to realize asymptotical cooperative cruise control of trains under the dual constraints of ensuring both position difference and velocity difference of adjacent trains in specified ranges throughout the whole process.
