Most real-world social networks are multi-graphs, where different kinds of relationships (e.g. chat, friendship) are possible between a pair of users. Existing network embedding techniques do not leverage signals from different edge types and thus perform inadequately on link prediction in such networks. We propose a method to mine network representation that effectively exploits heterogeneity in multi-graphs. We evaluate our model on a real-world, active social network where","authors_text":"Debdoot Mukherjee, Janu Verma, Srishti Gupta, Tanmoy Chakraborty","cross_cats":["cs.LG","stat.ML"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SI","submitted_at":"2019-02-07T10:42:08Z","title":"Heterogeneous Edge Embeddings for Friend Recommendation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1902.03124","kind":"arxiv","version":1},"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":"sha256:8d440dab1570956629448ef871145504baefbad966d87e7644f49545618ca821","target":"record","created_at":"2026-05-17T23:54:27Z","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":"1e19b124700d9181da87fdfce1d1034af4c7e6d082f328ebb1cfaef2cb72cf4b","cross_cats_sorted":["cs.LG","stat.ML"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SI","submitted_at":"2019-02-07T10:42:08Z","title_canon_sha256":"d3c68062dbb0ecca46df48ebfca9afb484abc18380ef21d15e52be566ed7e5e2"},"schema_version":"1.0","source":{"id":"1902.03124","kind":"arxiv","version":1}},"canonical_sha256":"e36a4966a97595d6348a53f9b72fc0758a7d4f0a25ac4f29c86e38d30f18989d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e36a4966a97595d6348a53f9b72fc0758a7d4f0a25ac4f29c86e38d30f18989d","first_computed_at":"2026-05-17T23:54:27.902151Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:54:27.902151Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Dp7D0F0Dio1rUuoIEIIaYtP1oEj6q2laNqLiaHRIo7sg2MydAkUpC9ezF9HyM/712/iatJCdXV8hF/OlqxOQAw==","signature_status":"signed_v1","signed_at":"2026-05-17T23:54:27.902668Z","signed_message":"canonical_sha256_bytes"},"source_id":"1902.03124","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8d440dab1570956629448ef871145504baefbad966d87e7644f49545618ca821","sha256:948c96f32a167d08d17b5622bc27e135f1f582331b7030dbb200fb00c384ec20"],"state_sha256":"b8088ff2b3d0ae58c7a280f3a64673df457d825e0be0c3f4411882a91c1a4b44"}
