Existing neuron-level mitigation methods equate editing with zeroing out neuron activations, but the activation only controls whether a neuron engages; the output vector is what writes to the residual stream and, through superposition, encodes multiple features. We propose output vector editing, a constrained-optimization weight edit that locates a small set of MLP neurons responsible for a memorized continuation and minimally modifies their output vectors to introd","authors_text":"Ahmad Dawar Hakimi, Hinrich Sch\\\"utze, Isabelle Augenstein, Kaiwei Lei","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CL","submitted_at":"2026-06-17T07:29:18Z","title":"Output Vector Editing for Memorization Mitigation in Large Language Models"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2606.18767","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":"sha256:50d64e5836efea41d6d85c002a1929bc0d43e19e437a55a65d97b99d4fb3f6f4","target":"record","created_at":"2026-06-19T16:11:46Z","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":"b47e39dfb89a251a1f985cf66f1b422cb9fac889062fd69a968fac394c9616ef","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CL","submitted_at":"2026-06-17T07:29:18Z","title_canon_sha256":"01e57adbb46aac7553a393dbcdd5df6945ec14fc674d23b5387439f02e7cb27d"},"schema_version":"1.0","source":{"id":"2606.18767","kind":"arxiv","version":1}},"canonical_sha256":"1baa98e2bdea52deb2d44ed2ed72c61db9e4636987d56b47a1ba645b7f2e7a9d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1baa98e2bdea52deb2d44ed2ed72c61db9e4636987d56b47a1ba645b7f2e7a9d","first_computed_at":"2026-06-19T16:11:46.853757Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-19T16:11:46.853757Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"bPdPHUB52VpU587O0SNQquJ1GZDNqfB+Y8U2qJ5dGdKwnnLBBBtPuOwNjl9igroxE8UCpaw8hiciXnZFUwTqCQ==","signature_status":"signed_v1","signed_at":"2026-06-19T16:11:46.854112Z","signed_message":"canonical_sha256_bytes"},"source_id":"2606.18767","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:50d64e5836efea41d6d85c002a1929bc0d43e19e437a55a65d97b99d4fb3f6f4","sha256:29b554265b245b4462ea7617fd670ab2be59f8c7cb953dfd25c76812e12a52c5"],"state_sha256":"5f213a485dfee70c8aaae3aaf3c3a7b6da0b1a9ec3b6706800a5386b78368d31"}
