CommunityAF: An Example-based Community Search Method via Autoregressive Flow

Summary: CommunityAF pairs incremental GNN embeddings with an autoregressive-flow generator and a learned scorer for scalable, fast-training example-based community search. A square-ranking loss and beam-search termination let it mimic structure metrics and deliver ~15% quality gain and 4–20× speedups. (summarized by gpt-5-mini on Feb 09 2026)
