proposed an inductive GCN (Graph Sample and Aggregate, GraphSage) that can be applied to dynamic graph data. GraphSage is not the embedded training for each node alone. However, it aggregates all the samplings from each node’s neighbors of a certain number (for example, calculating the mean...

This scheme is similar in spirit to the so-called sample average approximation scheme, which is widely used for the solution of stochastic programs. A graph coarsening (aggregation) scheme is used to compute an upper bound and to estimate the optimality gap of the approximate solution. The ...

Motivated by the observation that different nodes often require different iterations of aggregation to fully capture the structural information, in this paper, we propose to explicitly sample diverse iterations of aggregation for different nodes to boost the performance of GNNs. It is a challenging ...
Sample a random subset of possible permutations during each application of the aggregator, and only sum over that randomsubset. Employ acanonicalordering of the nodes in the neighborhood set; e.g., order the nodes in descending order according to their degree, with ties broken randomly. ...
and higher-order networks, enabling the aggregation of information from the nodes of the functional brain networks and the extraction of features for graph learning. Another strength is the use of GCN models for graph data, which have advantages over other convolutional neural networks, such as ...
(3) The third sample is from FreeSolv36, which focuses on the hydration free energy of small molecules in water. Fluoro and hydroxyl groups receive higher attention due to fluoro’s strong electron-acquiring ability and hydroxyl’s hydrophilicity, affecting the molecule’s interaction force with ...
