We propose ROM closure models that depend on the ROM residual. We illustrate the new residual-based data-driven ROM closure within the variational multiscale (VMS) framework and investigate it in the numerical simulation of a one-dimensional parameter-dependent convection-dominated convection-diffusion problem. For comparison purposes, we also investigate a streamline-upwind Petrov-Galerkin (SUPG) ROM stabilization strategy and the","authors_text":"Birgul Koc, Samuele Rubino, Tom\\'as Cha\\'on Rebollo, Traian Iliescu","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2022-07-29T20:12:02Z","title":"Residual Data-Driven Variational Multiscale Reduced Order Models for Parameter Dependent Problems"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2208.00059","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:f3b56499b5b582fba825fda8f20475b9840090125d99109e4252070f14f94cde","target":"record","created_at":"2026-07-05T06:16:46Z","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":"d4be04303191b2440001a29cc079a2bc89b9af8cdfe379af34953e44e8e6bf18","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2022-07-29T20:12:02Z","title_canon_sha256":"b069eb5037014b87a135af4b46143ea2073a624d8303a7f8d44fe7569f7494f7"},"schema_version":"1.0","source":{"id":"2208.00059","kind":"arxiv","version":2}},"canonical_sha256":"7ade758b65aebe4de82551b1dcd101f4e307ddeca289a64fa1997122b3abe948","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7ade758b65aebe4de82551b1dcd101f4e307ddeca289a64fa1997122b3abe948","first_computed_at":"2026-07-05T06:16:46.875821Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T06:16:46.875821Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"W4Sg8Dy+ImHDt1UIRkUVoGpa11L3pknMpQt8wX1RNcRM/59p8XUekhZ/IldmCvr8MuSgSCm/fjjs2CyRGyegCA==","signature_status":"signed_v1","signed_at":"2026-07-05T06:16:46.876282Z","signed_message":"canonical_sha256_bytes"},"source_id":"2208.00059","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f3b56499b5b582fba825fda8f20475b9840090125d99109e4252070f14f94cde","sha256:2c0108c7f7f26e0be4f9e196d1df4f3ceb802cb3eab988e805e4f372117ec336"],"state_sha256":"0892a16febed32d8402bf696fc7c810737f8971090b91355b510f888b9e6f3a9"}
