Bayesian Estimation of Panel Models under Potentially Sparse Heterogeneity

no code implementations20 Oct 2023 Hyungsik Roger Moon, Frank Schorfheide, Boyuan Zhang

We incorporate a version of a spike and slab prior, comprising a pointmass at zero ("spike") and a Normal distribution around zero ("slab") into a dynamic panel data framework to model coefficient heterogeneity.

HybridCVLNet: A Hybrid CSI Feedback System and its Domain Adaptation

no code implementations30 Mar 2023 Haozhen Li, Xinyu Gu, Boyuan Zhang, Dongliang Li, Zhenyu Liu, Lin Zhang

Deep Learning (DL)-based channel state information (CSI) feedback is a promising technique for the transmitter to accurately acquire the CSI of massive multiple-input multiple-output (MIMO) systems.

Incorporating Prior Knowledge of Latent Group Structure in Panel Data Models

no code implementations30 Nov 2022 Boyuan Zhang

We develop a constrained Bayesian grouped estimator that exploits researchers' prior beliefs on groups in a form of pairwise constraints, indicating whether a pair of units is likely to belong to a same group or different groups.

Easy Begun is Half Done: Spatial-Temporal Graph Modeling with ST-Curriculum Dropout

2 code implementations28 Nov 2022 Hongjun Wang, Jiyuan Chen, Tong Pan, Zipei Fan, Boyuan Zhang, Renhe Jiang, Lingyu Zhang, Yi Xie, Zhongyi Wang, Xuan Song

Spatial-temporal (ST) graph modeling, such as traffic speed forecasting and taxi demand prediction, is an important task in deep learning area.

Multi-task Deep Neural Networks for Massive MIMO CSI Feedback

no code implementations18 Apr 2022 Boyuan Zhang, Haozhen Li, Xin Liang, Xinyu Gu, Lin Zhang

Deep learning has been widely applied for the channel state information (CSI) feedback in frequency division duplexing (FDD) massive multiple-input multiple-output (MIMO) system.

NeuVV: Neural Volumetric Videos with Immersive Rendering and Editing

no code implementations12 Feb 2022 Jiakai Zhang, Liao Wang, Xinhang Liu, Fuqiang Zhao, Minzhang Li, Haizhao Dai, Boyuan Zhang, Wei Yang, Lan Xu, Jingyi Yu

We further develop a hybrid neural-rasterization rendering framework to support consumer-level VR headsets so that the aforementioned volumetric video viewing and editing, for the first time, can be conducted immersively in virtual 3D space.

Forecasting with Bayesian Grouped Random Effects in Panel Data

no code implementations5 Jul 2020 Boyuan Zhang

In this paper, we estimate and leverage latent constant group structure to generate the point, set, and density forecasts for short dynamic panel data.
