In this paper, we propose a general framework for designing graph kernels. The proposed framework capitalizes on the well-known message passing scheme on graphs. The kernels derived from the framework consist of two components. The first component is a kernel between vertices, while the second component is a kernel between graphs. The main idea behind the proposed framework is that the representations of the vertices are implicitly updated using an iterative proced","authors_text":"Giannis Nikolentzos, Michalis Vazirgiannis","cross_cats":["cs.LG"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ML","submitted_at":"2018-08-07T18:37:13Z","title":"Message Passing Graph Kernels"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1808.02510","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:a53f122ba4433f4baf64161dc5f2be44049c3620016d3a0e7f9bd4506743a94b","target":"record","created_at":"2026-05-18T00:08:35Z","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":"46d00ff620269abf811a856f90dc7a7f5a0e381cbf154017d835f2dcaaf97c81","cross_cats_sorted":["cs.LG"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ML","submitted_at":"2018-08-07T18:37:13Z","title_canon_sha256":"de19f6f794da3738cf9762f7e9ef43e50c2657e0f271ef7e0f73b8452cf91a71"},"schema_version":"1.0","source":{"id":"1808.02510","kind":"arxiv","version":1}},"canonical_sha256":"c413082931a71b4c845670a83084c2b33284c6505b1d002c7c1612a7ac79cc3e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c413082931a71b4c845670a83084c2b33284c6505b1d002c7c1612a7ac79cc3e","first_computed_at":"2026-05-18T00:08:35.221656Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:08:35.221656Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"1R0BxN2GEgGrSCyJGbp3pOB2nj2F1OTUZ+pKowWTfJ5oYCL7kd5wktwTlOcXnio/7ppNpkgZMN3Df9mPV1JvCw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:08:35.222351Z","signed_message":"canonical_sha256_bytes"},"source_id":"1808.02510","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a53f122ba4433f4baf64161dc5f2be44049c3620016d3a0e7f9bd4506743a94b","sha256:3a8488b0658ad54d8499175f0a5015a453c287a8f7503aabc6bc0e4f18b9ec15"],"state_sha256":"1e24ce96f3825e6d12b6c138609c25ae1ee67886adaf1c886ffd3cdce3595cac"}
