4DBInfer: A 4D Benchmarking Toolbox for Graph-Centric Predictive Modeling on Relational DBs

1 code implementation28 Apr 2024 Minjie Wang, Quan Gan, David Wipf, Zhenkun Cai, Ning li, Jianheng Tang, Yanlin Zhang, Zizhao Zhang, Zunyao Mao, Yakun Song, Yanbo Wang, Jiahang Li, Han Zhang, Guang Yang, Xiao Qin, Chuan Lei, Muhan Zhang, Weinan Zhang, Christos Faloutsos, Zheng Zhang

Although RDBs store vast amounts of rich, informative data spread across interconnected tables, the progress of predictive machine learning models as applied to such tasks arguably falls well behind advances in other domains such as computer vision or natural language processing.

HAPNet: Toward Superior RGB-Thermal Scene Parsing via Hybrid, Asymmetric, and Progressive Heterogeneous Feature Fusion

1 code implementation4 Apr 2024 Jiahang Li, Peng Yun, Qijun Chen, Rui Fan

In this study, we take one step toward this new research area by exploring a feasible strategy to fully exploit VFM features for RGB-thermal scene parsing.

On the Initialization of Graph Neural Networks

1 code implementation5 Dec 2023 Jiahang Li, Yakun Song, Xiang Song, David Paul Wipf

In this paper, we analyze the variance of forward and backward propagation across GNN layers and show that the variance instability of GNN initializations comes from the combined effect of the activation function, hidden dimension, graph structure and message passing.

RoadFormer: Duplex Transformer for RGB-Normal Semantic Road Scene Parsing

no code implementations19 Sep 2023 Jiahang Li, Yikang Zhang, Peng Yun, Guangliang Zhou, Qijun Chen, Rui Fan

Additionally, we release SYN-UDTIRI, the first large-scale road scene parsing dataset that contains over 10, 407 RGB images, dense depth images, and the corresponding pixel-level annotations for both freespace and road defects of different shapes and sizes.

Network In Graph Neural Network

no code implementations23 Nov 2021 Xiang Song, Runjie Ma, Jiahang Li, Muhan Zhang, David Paul Wipf

However, wider hidden layers can easily lead to overfitting, and incrementally adding more GNN layers can potentially result in over-smoothing. In this paper, we present a model-agnostic methodology, namely Network In Graph Neural Network (NGNN ), that allows arbitrary GNN models to increase their model capacity by making the model deeper.
