Channel Measurements and Modeling for Dynamic Vehicular ISAC Scenarios at 28 GHz

no code implementations1 Mar 2024 Zhengyu Zhang, Ruisi He, Bo Ai, Mi Yang, Xuejian Zhang, Ziyi Qi, Yuan Yuan

Integrated sensing and communication (ISAC) is a promising technology for 6G, with the goal of providing end-to-end information processing and inherent perception capabilities for future communication systems.

Characterization of Wireless Channel Semantics: A New Paradigm

no code implementations1 Mar 2024 Zhengyu Zhang, Ruisi He, Mi Yang, Xuejian Zhang, Ziyi Qi, Yuan Yuan, Bo Ai

Recently, deep learning enabled semantic communications have been developed to understand transmission content from semantic level, which realize effective and accurate information transfer.

Non-stationarity Characteristics in Dynamic Vehicular ISAC Channels at 28 GHz

no code implementations1 Mar 2024 Zhengyu Zhang, Ruisi He, Mi Yang, Xuejian Zhang, Ziyi Qi, Hang Mi, Guiqi Sun, Jingya Yang, Bo Ai

It is necessary to carry out measurement, characterization, and modeling for vehicular ISAC channels as the basic theoretical support for system design.

A Cluster-Based Statistical Channel Model for Integrated Sensing and Communication Channels

no code implementations1 Mar 2024 Zhengyu Zhang, Ruisi He, Bo Ai, Mi Yang, Yong Niu, Zhangdui Zhong, Yujian Li, Xuejian Zhang, Jing Li

However, some important features of ISAC channels have not been well characterized, for example, most existing ISAC channel models consider communication channels and sensing channels independently, whereas ignoring correlation under the consistent environment.

Towards the Better Ranking Consistency: A Multi-task Learning Framework for Early Stage Ads Ranking

no code implementations12 Jul 2023 Xuewei Wang, Qiang Jin, Shengyu Huang, Min Zhang, Xi Liu, Zhengli Zhao, Yukun Chen, Zhengyu Zhang, Jiyan Yang, Ellie Wen, Sagar Chordia, Wenlin Chen, Qin Huang

In order to pass better ads from the early to the final stage ranking, we propose a multi-task learning framework for early stage ranking to capture multiple final stage ranking components (i. e. ads clicks and ads quality events) and their task relations.

AdaTT: Adaptive Task-to-Task Fusion Network for Multitask Learning in Recommendations

1 code implementation11 Apr 2023 Danwei Li, Zhengyu Zhang, Siyang Yuan, Mingze Gao, Weilin Zhang, Chaofei Yang, Xi Liu, Jiyan Yang

However, MTL research faces two challenges: 1) effectively modeling the relationships between tasks to enable knowledge sharing, and 2) jointly learning task-specific and shared knowledge.

P$^2$SDF for Neural Indoor Scene Reconstruction

no code implementations1 Mar 2023 Jing Li, Jinpeng Yu, Ruoyu Wang, Zhengxin Li, Zhengyu Zhang, Lina Cao, Shenghua Gao

As the unsupervised plane segments are usually noisy and inaccurate, we propose to assign different weights to the sampled points on the plane in plane estimation as well as the regularization loss.

Identification and Auto-debiased Machine Learning for Outcome Conditioned Average Structural Derivatives

no code implementations15 Nov 2022 Zequn Jin, Lihua Lin, Zhengyu Zhang

One contribution of this paper is that we establish some close relationships between the \textit{outcome conditioned average partial effects} and a class of parameters measuring the effect of counterfactually changing the distribution of a single covariate on the unconditional outcome quantiles.
