whosei-th row is the feature vector of nodei. We use an\(n\times c\)matrixYto denote the label matrix, wherecis the number of categories. When a nodeibelongs to categoryj,\(Y_{ij}=1\)while\(Y_{ij'}=0\)for
The self-loop adjacency matrix, denoted as A, is obtained by adding the identity matrix I to the original adjacency matrix A 自循环邻接矩阵,记为 A,通过在原始邻接矩阵 A 上添加同位矩阵 I 而得到。 W is theparameter matrix. This matrix captures the self-connections andlocal connectivity of nod...
However, the questions that must be asked before implementation are: “Is the algorithm efficient?”“Can the algorithm complete the task within an acceptable amount of time for a specific set of data derived from a practical application?” As we will see in the next section, there are ...

To determine those, typically, we use the Louvain algorithm in the implementation of [37] at suitable resolutions, but PAGA works with any underlying clustering algorithm or experimentally generated groupings of observations. In the present work, we exclusively used the Louvain algorithm. In the ...
GAN-based models by design allow easy implementation of controllable sampling, e.g., by introducing a property discriminator for desired properties. MolGAN [7] learns to sample the probability matrix for the node feature and edge feature, respectively. It directly generates new graphs by taking ...

For simplicity of implementation, during validation / test set evaluation, we perform layer propagation using the full graph adjacency matrix. For Amazon or Yelp, this may cause memory issue for some GPUs. If an out-of-memory error occurs, please use the--cpu_evalflag to force the val / ...
