Anchor Preprocessing and Utility Functions

get_anchor_pairs	Get anchor node pairs between two graphs identified by gid1 and gid2.
get_pairwise_anchor_pairs	Get anchor node pairs for all pairs of graphs.
get_anchor_embeddings	Generate one-hot anchor embeddings for nodes in a graph based on given anchor nodes.
get_rwr_embeddings	Compute Random Walk with Restart (RWR) embeddings for nodes in a graph based on given anchor nodes.
merge_pyg_graphs_on_anchors	Merge multiple PyG graphs into a single graph based on anchor links.
infer_anchors_from_degree	Infer anchor node pairs based on degree similarity.
infer_anchors_from_attributes	Infer anchor node pairs based on attribute similarity.

Noise Injection

add_edge_noises	Add structural noise to graphs in a PlanetAlign dataset by perturbing edges.
add_attr_noises	Add attribute noise to graphs in a PlanetAlign dataset by perturbing node attributes.
add_sup_noises	Add supervision noise to graphs in a PlanetAlign dataset by injecting noisy anchors.

Visualization Functions

plot_alignment_matrix	Visualize an alignment matrix as a heatmap.
plot_alignment_matrix_topk	Visualizes an alignment matrix as a scatter plot of the top-k largest entries.
