Decentralizing Coherent Joint Transmission Precoding via Fast ADMM with Deterministic Equivalents

no code implementations28 Mar 2024 Xinyu Bian, Yuhao Liu, Yizhou Xu, Tianqi Hou, Wenjie Wang, Yuyi Mao, Jun Zhang

Simulation results demonstrate the effectiveness of our proposed decentralized precoding scheme, which achieves performance similar to the optimal centralized precoding scheme.

Decentralizing Coherent Joint Transmission Precoding via Deterministic Equivalents

no code implementations15 Mar 2024 Yuhao Liu, Xinyu Bian, Yizhou Xu, Tianqi Hou, Wenjie Wang, Yuyi Mao, Jun Zhang

In order to control the inter-cell interference for a multi-cell multi-user multiple-input multiple-output network, we consider the precoder design for coordinated multi-point with downlink coherent joint transmission.

When Does Feature Learning Happen? Perspective from an Analytically Solvable Model

no code implementations13 Jan 2024 Yizhou Xu, Liu Ziyin

We identify and solve a hidden-layer model that is analytically tractable at any finite width and whose limits exhibit both the kernel phase and the feature learning phase.

Continual Driving Policy Optimization with Closed-Loop Individualized Curricula

1 code implementation25 Sep 2023 Haoyi Niu, Yizhou Xu, Xingjian Jiang, Jianming Hu

To tackle this challenge, a surge of research in scenario-based autonomous driving has emerged, with a focus on generating high-risk driving scenarios and applying them to conduct safety-critical testing of AV models.

Approximate Message Passing for Multi-Layer Estimation in Rotationally Invariant Models

1 code implementation3 Dec 2022 Yizhou Xu, Tianqi Hou, Shansuo Liang, Marco Mondelli

We consider the problem of reconstructing the signal and the hidden variables from observations coming from a multi-layer network with rotationally invariant weight matrices.
