Generate a synthetic differential graph pair for testing context-aware node embeddings

Produces two graphs sharing the same backbone but differing in defined regions. Community 1 is a stable negative control, identical across both graphs. Community 2 contains a hub node demoted to a peripheral node in graph 2. Two bridge nodes span communities 2 and 3 in graph 1 but are fully embedded within community 3 in graph 2. Exclusive nodes appear in only one graph.

Usage

rs_differential_graph_data(n_stable, n_comm2, n_comm3, n_exclusive)

Arguments

n_stable

Integer. Number of nodes in the stable negative-control community.

n_comm2

Integer. Number of regular nodes in community 2, excluding the hub.

n_comm3

Integer. Number of nodes in community 3, excluding bridge nodes.

n_exclusive

Integer. Number of exclusive nodes in each graph.

Value

A named list with: g1_edges (from, to), g1_nodes (node, cluster), g2_edges (from, to), g2_nodes (node, cluster), data_info (shared_nodes, is_differential, g1_only, g2_only).
