Existing hallucination detection methods leveraging hidden states predominantly focus on static and isolated representations, overlooking their dynamic evolution across layers, which limits efficacy. To address this limitation, we shift the focus to the hidden state update process and introduce a novel metric, the ICR Score (Information Contribution to Residual Stream), which quantifies the contribution of modules to the hidden states' upd","authors_text":"Huixuan Zhang, Junzhe Zhang, Xiaojun Wan, Xinyu Hu, Zhenliang Zhang","cross_cats":["cs.AI"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2025-07-22T11:44:26Z","title":"ICR Probe: Tracking Hidden State Dynamics for Reliable Hallucination Detection in LLMs"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2507.16488","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:ddc830401c7c50f6d65da6871010fdbe41fc18be6b493858878ad7ee27ab1b9d","target":"record","created_at":"2026-07-05T11:41:10Z","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":"f876624d366f5d63e75ccc9a74af210d068dbb825c59b4535b48613af43c0c9d","cross_cats_sorted":["cs.AI"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2025-07-22T11:44:26Z","title_canon_sha256":"88ba1d0a1c727a7f4af41f72fc0382eb2a9c4dd2922e8cab5454a6d9728a0680"},"schema_version":"1.0","source":{"id":"2507.16488","kind":"arxiv","version":1}},"canonical_sha256":"872a0c37a6d18533f161b234c00586dc04cbba86486b8609c05b8a7318bb2b93","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"872a0c37a6d18533f161b234c00586dc04cbba86486b8609c05b8a7318bb2b93","first_computed_at":"2026-07-05T11:41:10.372593Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:41:10.372593Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ffEzirfzLYZB3zSKfIhmevL1mU9E8MPSTG7lqSINmeRjWsagpUD+p2TkqCgXPGvhB2XDDXdvgbUsR9wvjo+eDg==","signature_status":"signed_v1","signed_at":"2026-07-05T11:41:10.373013Z","signed_message":"canonical_sha256_bytes"},"source_id":"2507.16488","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ddc830401c7c50f6d65da6871010fdbe41fc18be6b493858878ad7ee27ab1b9d","sha256:4613b3bd730100b3f385fdee611f6e23d620904f43b82723d6ba764d7d45899a"],"state_sha256":"3d40cde5871cbac4f9adcf552481145d9b86078f001a9ce621ef3f3baf1bb7c4"}
