WebThe # computation flow underlying a DAG can be executed in one sweep, by # calling ``prop_flows``. # # ``prop_flows`` accepts a list of UDFs. The code below defines node … 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. The main contributions of the work are described below:

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 ...
