ShiftMatch is inspired by the training-data-dependent \"EmpCov\" priors from Izmailov et al. (2021a), and efficiently matches test-time spatial correlations to those at training time. Critically, ShiftMatch is designed to leave the neural network's training time likelihood unchanged, allowing it to use publicly available samples from pre-trained BNNs. Using pre-trained HMC samples, ShiftMatch gives strong performance improvements on CIFAR-10-C, outperforms EmpCov prior","authors_text":"Laurence Aitchison, Xi Wang","cross_cats":["cs.AI"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2022-06-24T16:08:46Z","title":"Robustness to corruption in pre-trained Bayesian neural networks"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2206.12361","kind":"arxiv","version":3},"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":"sha256:62bb1d5ee8b912739971d61cbf1e4f540a7b0d4ffe78edf3dfc9266d6f7adb3f","target":"record","created_at":"2026-07-05T05:44:49Z","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":"9646049617ea269b597aace1e5247cc06ae76b5f5b800a74bc974f60a0b8935f","cross_cats_sorted":["cs.AI"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2022-06-24T16:08:46Z","title_canon_sha256":"e1a0e9194c5219cf9bcc9401307f84d9d6b20363ac19cdd14108c74d45c9776e"},"schema_version":"1.0","source":{"id":"2206.12361","kind":"arxiv","version":3}},"canonical_sha256":"37a55f0fecaf747b3ce83a845dfffcd0325ec1a998ecec7f41f9472c06c21ce6","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"37a55f0fecaf747b3ce83a845dfffcd0325ec1a998ecec7f41f9472c06c21ce6","first_computed_at":"2026-07-05T05:44:49.214174Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:44:49.214174Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"PYVbpSY3vKPaIX1AAITydDiymHiE7cMHIyiPNnA3Frbaby+FpBzEQAY4h9C+lU2tmlGNEb0DiU4oSGxrEQZUDw==","signature_status":"signed_v1","signed_at":"2026-07-05T05:44:49.214704Z","signed_message":"canonical_sha256_bytes"},"source_id":"2206.12361","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:62bb1d5ee8b912739971d61cbf1e4f540a7b0d4ffe78edf3dfc9266d6f7adb3f","sha256:95c47d50bc9b3d7ea3d55bf9a4d4056558446422506700ce0f9d7c51b403d310"],"state_sha256":"8e0c0e38b44baa85af6717dd571ea6921a8026a9df257474f62450816b809928"}
