Recent task-specific attention operators can compress deep Transformer stacks into a few layers by performing multi-hop state propagation within a single layer, but their dense evaluation remains expensive. We show that in this setting, learned attention is strongly structured: most mass concentrates in local block-diagonal neighborhoods with a light cross-block residue. Exploiting this, we derive a blockwise evaluation of a resolvent-style operator that keeps within-block interacti","authors_text":"Alexandre Allauzen, Erwan Fagnou, Hangyue Zhao, Paul Caillon","cross_cats":["cs.CL"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"cs.LG","submitted_at":"2026-05-21T13:35:48Z","title":"Structured-Sparse Attention for Entity Tracking with Subquadratic Sequence Complexity"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2605.22476","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":"sha256:4fca51b67d788b83dd5deb8fe42dc8c88fbb3920e19200ca5eb51145d4408f4b","target":"record","created_at":"2026-05-22T01:04:44Z","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":"61060a42ae5660915466af53a33f95a1c9975d3ee110056d7f986ac641885574","cross_cats_sorted":["cs.CL"],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"cs.LG","submitted_at":"2026-05-21T13:35:48Z","title_canon_sha256":"3435f3403c2cf742c62eaee81e1359b06cee1f5dbad03959e6c4d0331ebe401b"},"schema_version":"1.0","source":{"id":"2605.22476","kind":"arxiv","version":1}},"canonical_sha256":"da5fa2b1a7a2f4f60539c1d58eb6dd5d3f4efb727c435cd19022b5cea56660ec","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"da5fa2b1a7a2f4f60539c1d58eb6dd5d3f4efb727c435cd19022b5cea56660ec","first_computed_at":"2026-05-22T01:04:44.714091Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-22T01:04:44.714091Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"E9dzNx3kuun+71psSgcgYytL1i8yLfPoD5fvfcdNjrq3lltHCINXT/yvRU+PNnC5J3A2qPwDUHTwIeh4BG5FCw==","signature_status":"signed_v1","signed_at":"2026-05-22T01:04:44.714932Z","signed_message":"canonical_sha256_bytes"},"source_id":"2605.22476","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4fca51b67d788b83dd5deb8fe42dc8c88fbb3920e19200ca5eb51145d4408f4b","sha256:f6d44630c2c81b892641b224aa0b6a5086063dc9c88eeaebb8e4eda3e5ccdcce"],"state_sha256":"cd85eb00e07a75e8a614afa854afb58709e46ef9a7b7de0702af1e8edab1a969"}
