WebIn this paper, we propose GraphHeat, leveraging heat kernel to enhance low-frequency filters and enforce smoothness in the signal variation on the graph. GraphHeat leverages the local structure of target node under heat diffusion to determine its neighboring nodes flexibly, without the constraint of order suffered by previous methods.

And then, it uses soft labels to guide the feature aggregation via attention mechanism. Unlike the prior graph attention networks, SLGAT allows paying more attention to the features … pocket knife storage chest

Web1 Note that we do not report results of SPAGAN and GraphHeat in this experiment, because we cannot reproduce these two methods without official implementation. 2 The label rate of Cora, Citeseer and Pubmed are 0.052, 0.036 and 0.003 respectively. WebWelcome to IJCAI IJCAI Web(t>0). GraphHeat adopts Heat Kernel to design a poly-nomial filter. As a k-hop GNN, in GraphHeat each degree of the polynomial is a smooth exponential low-pass filter. For instance, the k-degree filter is e ktL. Based on Heat Kernel, GDC (HKPR) uses Heat Kernel PageRank Chung (2007) as a diffusion method. In these GNNs, Heat Kernel has shown pocket knife that shoots out
