Joint Spectrum and Power Allocation for V2X Communications with Imperfect CSI

no code implementations21 Feb 2023 Peng Wang, Weihua Wu, Jiayi Liu, Guanhua Chai, Li Feng

More specifically, Bernstein approximations are employed to convert the chance constraint into a calculable constraint, and Bisection search method is proposed to obtain the optimal allocation solution with low complexity.


Learning Optimal K-space Acquisition and Reconstruction using Physics-Informed Neural Networks

no code implementations CVPR 2022 Wei Peng, Li Feng, Guoying Zhao, Fang Liu

While most of these methods focus on designing novel reconstruction networks or new training strategies for a given undersampling pattern, e. g., Cartesian undersampling or Non-Cartesian sampling, to date, there is limited research aiming to learn and optimize k-space sampling strategies using deep neural networks.

Interaction Detection Between Vehicles and Vulnerable Road Users: A Deep Generative Approach with Attention

no code implementations9 May 2021 Hao Cheng, Li Feng, Hailong Liu, Takatsugu Hirayama, Hiroshi Murase, Monika Sester

Intersections where vehicles are permitted to turn and interact with vulnerable road users (VRUs) like pedestrians and cyclists are among some of the most challenging locations for automated and accurate recognition of road users' behavior.

SANTIS: Sampling-Augmented Neural neTwork with Incoherent Structure for MR image reconstruction

no code implementations8 Dec 2018 Fang Liu, Lihua Chen, Richard Kijowski, Li Feng

The undersampled images are generated by a fixed undersampling pattern in the training, and the trained network is then applied to reconstruct new images acquired with the same pattern in the inference.
