WebMore specifically, :obj:`sizes` denotes how much neighbors we want to sample for each node in each layer. This module then takes in these :obj:`sizes` and iteratively samples :obj:`sizes [l]` for each node involved in layer :obj:`l`. In the next layer, sampling is repeated for the union of nodes that were already encountered. The actual ... WebApr 14, 2024 · This can improve the model's performance if edge features are relevant for the task but also create more complexity. You might want to consider adding more GNN layers to the model (to allow for more neighbor-hops). Artificial Nodes led to an increase in AUC of about 2%. Your own Edge Feature architecture.
Webods provided by DGL, including node-wise neighbor sampling and LADIES. We show that GNS achieves state-of-the-art model accu-racy while speeding up training by a factor of 2 ×−4×compared with node-wise sampling and by a factor of 2 ×−14×compared with LADIES.

Webthe Deep Graph Library (DGL) (Wang et al.,2024). Batch preparation entails expanding the sampled neighborhood for a mini-batch of nodes and slicing out the feature vec-tors of all involved nodes. The corresponding subgraph and feature vectors must then be transferred to the GPUs, since the entire graph and feature data are often too large to ...
