尽管上述现象仅在连通图上成立,但是作者通过实验发现在连通分量中上述现象同时也存在, full graph (Full),largest connected component (LCC),原始 cora 数据集中包含 78 个连通分量,基于此计算特征传播算子然后在随机生成的 100 维特征(相关性很低接近于 0)上执行 feature propagation(a)。 2.2 Transformation can ...
paper:Feature Overcorrelation in Deep Graph Neural Networks: A New Perspective code:https://github.com/ChandlerBang/DeCorr 这是一篇做的很扎实的工作,动机、实验设置以及数理推导都很合理,在oversmooth之外提出了over correlation。 Contributions 对深层GNN提出了特征过相关(over correlation)问题,并通过实验和理论...
被引量: 9发表: 2012年 The Impact of Edge Correlations in Random Networks Random graphs are frequently used models of real-life random networks. The classical Erds–Rényi random graph model is very well explored and has numerous... A. Faragó - 《Complex Syst》 被引量: 0发表: 2021年 ...
In order to demonstrate the efficiency of the proposed approaches, a system called CGraph is developed and extensive experiments have been con- ducted. The experimental results show that CGraph im- proves the throughput of the CGP jobs by up to 2.31 times in comparison with the existing ...

to produce more similar graph to the one I was looking for (The one generated with R). Also an issue with circle size for correlations in [-1,1] has been solved. This code can produce triangular display as well. Custom colormap and a sample graph that I generated is attached. ...

Our study reveals new theoretical insights into over-smoothing and feature over-correlation in deep graph neural networks. We show the prevalence of invariant subspaces, demonstrating a fixed relative behavior that is unaffected by feature transformations. Our work clarifies recent observations related to...
I also used a line graph, which makes the visual connection stand out more than it deserves. Note Mathematically what I showed is true, but it is intentionally misleading. If you click on any of the charts that abuse this, you can scroll down to see a version that starts at zero. ...
