29.11.2021 · GraphSage (Sample and Aggregate) algorithm is an inductive (it can generalize to unseen nodes) deep learning method developed by Hamilton, Ying, and Leskovec (2017) for graphs used to generate...
There are three SAGEConv examples provided by pytorch geometric. I am wondering is the size of number of neighbors in dataloader always the same as number of SAGEConv layer? For example 1: reddit, num_neighbors=[25, 10] in Neighborloader, and there are two SAGEConv in SAGE(torch.nn.Module) class. Similar setting for example 2 and 3.

04.09.2021 · Note that here I am using the provided example in PyTorch Geometric repository with few tricks. GraphSAGE Specifics The key idea of GraphSAGE is sampling strategy. This enables the architecture to scale to very large scale applications. The sampling implies that, at each layer, only up to K number of neighbours are used.
13.10.2020 · Sometimes we encounter large graphs that force us beyond the available memory of our GPU or CPU. In t hese cases, we can utilize graph sampling techniques. PyTorch Geometric is a graph deep learning library that allows us to easily implement many graph neural network architectures with ease. The library contains many standard graph deep learning datasets like …
