Recently, transformer-based models have demonstrated that table-structure can be recognized with impressive accuracy using Image-to-Markup-Sequence (Im2Seq) approaches. Taking only the image of a table, such models predict a sequence of tokens (e.g. in HTML, LaTeX) which represent the structure of the table. Since the token representation of the table structure has a significant impact on the accuracy and run-time performance of any Im2Seq model, we investigate in this paper how table-structure representati","authors_text":"Ahmed Nassar, Christoph Auer, Maksym Lysak, Nikolaos Livathinos, Peter Staar","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2023-05-05T09:38:47Z","title":"Optimized Table Tokenization for Table Structure Recognition"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2305.03393","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:eda1f71eb60b960705c5708f10c9446872dc38272e32062eb0007b18d232d806","target":"record","created_at":"2026-07-05T06:07:22Z","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":"a5ec6e2ad6857edb52ffcbb54c6af49565505bd2488d73211c06d5c2f782eeeb","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2023-05-05T09:38:47Z","title_canon_sha256":"562920172433b37e895f72a00368c0113ae3bb326c29e8d1fd2d25deee5bbc76"},"schema_version":"1.0","source":{"id":"2305.03393","kind":"arxiv","version":1}},"canonical_sha256":"a253575faaaada4bdfa0d3cac7eee95a22edf2cb6493585c33fdfb9d4c921ce1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a253575faaaada4bdfa0d3cac7eee95a22edf2cb6493585c33fdfb9d4c921ce1","first_computed_at":"2026-07-05T06:07:22.871473Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T06:07:22.871473Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"JOzn+1G6tygCDB808JYhIf90saeArrayq7qbyJJ2GJlPe7O+2Hw9ELDd6TGReEvZcXyBOFhtBsios7uoWEwaCg==","signature_status":"signed_v1","signed_at":"2026-07-05T06:07:22.872113Z","signed_message":"canonical_sha256_bytes"},"source_id":"2305.03393","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:eda1f71eb60b960705c5708f10c9446872dc38272e32062eb0007b18d232d806","sha256:cb4351eb8b16cf82e84c066802952b9da786cafb19c7852ea12db0620c1fa874"],"state_sha256":"e4867f7c50fb9b2e14efabe0c5e6e4f540c49054c7328e3ccf65b73362bb4dc6"}
