However, these methods do not explicitly preserve the coupled geometry between the pretrained left and right singular bases. Motivated by recent minimum-perturbation theory, which shows that stable finetuning follows a coherent SVD rotation in which a single orthogonal $Q$ acts on both the left singular basis $U_0$ and the right singular basis $V_0$, we prove a p","authors_text":"Pengcheng Wang, Wei Jiang, Wei Wang, Ziran Liu","cross_cats":["cs.LG"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"stat.ML","submitted_at":"2026-06-30T20:00:47Z","title":"CORA: Per-Slice Coherent Orthogonal Rotation for SVD-based Low-Rank Adaptation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2607.02576","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":"sha256:9c052b52d515446d8b67a222cb8c584d1095f23655bae2fc830a91501b99500d","target":"record","created_at":"2026-07-07T00:16:01Z","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":"cdf04d7c0ac5fb39b9dc3d88aae375e27051fc3c5c8a15528e594b9bb2b1920b","cross_cats_sorted":["cs.LG"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"stat.ML","submitted_at":"2026-06-30T20:00:47Z","title_canon_sha256":"74fc21a2360d2662718e9b8ec032b45366b65c19cfaac33128e43a2f4b769d71"},"schema_version":"1.0","source":{"id":"2607.02576","kind":"arxiv","version":1}},"canonical_sha256":"a239929a3f09b0c3100d6ad173638a76d8757ad4dc07a14e920cebbfcc05cede","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a239929a3f09b0c3100d6ad173638a76d8757ad4dc07a14e920cebbfcc05cede","first_computed_at":"2026-07-07T00:16:01.268104Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-07T00:16:01.268104Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"d6gwuC1O6MZRmysdYblnadDo+Mh23B9qatLzNz+EjyuiSdTK7Zl7fyrjskemSdcoRI7/deK9DU11752IYcyFAA==","signature_status":"signed_v1","signed_at":"2026-07-07T00:16:01.268872Z","signed_message":"canonical_sha256_bytes"},"source_id":"2607.02576","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9c052b52d515446d8b67a222cb8c584d1095f23655bae2fc830a91501b99500d","sha256:a4ccc27bb53dbe58428f011f54e368f21f9159ce6a39ac9a46858adade165785"],"state_sha256":"13c7be961584adf007f295ff41ed29553f35bbb24ccaff431db5ef59b2c0c1af"}
