AReaL: A Large-Scale Asynchronous Reinforcement Learning System for Language Reasoning

1 code implementation30 May 2025 Wei Fu, Jiaxuan Gao, Xujie Shen, Chen Zhu, Zhiyu Mei, Chuyi He, Shusheng Xu, Guo Wei, Jun Mei, Jiashu Wang, Tongkai Yang, Binhang Yuan, Yi Wu

Most existing large-scale RL systems for LLMs are synchronous, alternating generation and training in a batch setting where rollouts in each training batch are generated by the same model.

Cramér-Rao Bounds of Near-Field Positioning Based on Electromagnetic Propagation Model

no code implementations2 Jul 2022 Ang Chen, Li Chen, Yunfei Chen, Changsheng You, Guo Wei, F. Richard Yu

In this paper, we improve the near-field positioning technology from the classical spherical wavefront model (SWM) to the more accurate and true electromagnetic propagation model (EPM).

Blind Diagnosis for Millimeter-wave Large-scale Antenna Systems

no code implementations25 Jan 2021 Rui Sun, Weidong Wang, Li Chen, Guo Wei, Wenyi Zhang

Millimeter-wave (mmWave) communication systems rely on large-scale antenna arrays to combat large path-loss at mmWave band.

Diagnosis of Intelligent Reflecting Surface in Millimeter-wave Communication Systems

1 code implementation11 Jan 2021 Rui Sun, Weidong Wang, Li Chen, Guo Wei, Wenyi Zhang

In the second case where only partial CSI is available, we jointly exploit the sparsity of the millimeter-wave channel and the failure, and adopt compressed sparse and low-rank matrix recovery algorithm to decouple channel and failure.
