In the present work, we developed and evaluated a new approach that learns the building blocks of graphs that can be used to understand and generate new realistic graphs. Our key insight is that a graph's clique tree encodes robust and precise information. We show that a Hyperedge Replacement Grammar (HRG) can be extracted from the clique tree, and we develop a fixed-size graph generation algorithm that can be used to produce new graphs of a specified size. In experiments on large real-world graphs, we sho","authors_text":"David Chiang, Salvador Aguinaga, Tim Weninger","cross_cats":["cs.FL"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.SI","submitted_at":"2018-02-21T01:32:10Z","title":"Learning Hyperedge Replacement Grammars for Graph Generation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1802.08068","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:e2ebb48a48cfa48508acd90f5edb27fdc05a570fa6762c369e86eb03f832e863","target":"record","created_at":"2026-05-18T00:22:44Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"f48e4404ef9c0369927f784a5251fcc02afd0459430d6566703295ec8a5b17af","cross_cats_sorted":["cs.FL"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.SI","submitted_at":"2018-02-21T01:32:10Z","title_canon_sha256":"3475b8a2f40c487bb8b745683a03849717d33ba39e72ad6c3f7aabb077349b05"},"schema_version":"1.0","source":{"id":"1802.08068","kind":"arxiv","version":2}},"canonical_sha256":"25abaa641e534e01701051ec9b555b6e8e61173f1de830e108ebd8ad0869b9ee","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"25abaa641e534e01701051ec9b555b6e8e61173f1de830e108ebd8ad0869b9ee","first_computed_at":"2026-05-18T00:22:44.092721Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:22:44.092721Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"rEtBmDm0cokc6OoPYNp/V1Kzi2L98kVwqI3gqP7/RXW3B+qCv/xNx58gEBZ4YSUQF3SjNCoqGUIMtehUiTnnAQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:22:44.093158Z","signed_message":"canonical_sha256_bytes"},"source_id":"1802.08068","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e2ebb48a48cfa48508acd90f5edb27fdc05a570fa6762c369e86eb03f832e863","sha256:097e2d009d1ddb0f579c8fbc02265b35934ae7f839c1efe805c8ca6168c0cefa"],"state_sha256":"610f2ebf22da3506a59f6d4915f259e4dc44d26768533146c0ea3f0497ac060f"}
