Unfortunately, such data has been difficult to faithfully represent in a way that most machine learning techniques would expect, i.e. as a real-valued vector of a fixed, pre-specified size. In this work, we introduce a novel approach that compiles structured data into a satisfiability problem which has in its set of solutions at least (and often only) the input data. The satisfiability problem is constructed from constraints which are generated automatically a priori from a given signature, thus trivially ","authors_text":"Achille Fokoue, Constantine Nakos, Kenneth Forbus, Lingfei Wu, Maria Chang, Maxwell Crouse, Michael Witbrock, Pavan Kapanipathi, Ryan Musa","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.AI","submitted_at":"2019-01-09T00:26:00Z","title":"High-Fidelity Vector Space Models of Structured Data"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1901.02565","kind":"arxiv","version":2},"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:bb8fd2aa37c5956ed52a2040f3410218f9761fd8f3577ac3c3f89fc4c6d6c403","target":"record","created_at":"2026-05-17T23:56:22Z","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":"75ec5046e967d986be92818f09eaa9de4b12e171797c9a952d929acd94e1e0ba","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.AI","submitted_at":"2019-01-09T00:26:00Z","title_canon_sha256":"037a64f04d749a23f92e43852e767c16901074d328fb26594655b1b3f0e529b4"},"schema_version":"1.0","source":{"id":"1901.02565","kind":"arxiv","version":2}},"canonical_sha256":"f1a1873223ef33f79e468665c77cd4d68dc65ba90ac031ea23e38ef27ea8268b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f1a1873223ef33f79e468665c77cd4d68dc65ba90ac031ea23e38ef27ea8268b","first_computed_at":"2026-05-17T23:56:22.702522Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:56:22.702522Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"tv8e8W70WmgBj/veQAxi6K2dD+kuk2vRF0UL3FD4FRQ9EKAKiMCF4fuypeAKudbwCmQwx1eZ28ZJkT4OQysPDQ==","signature_status":"signed_v1","signed_at":"2026-05-17T23:56:22.702984Z","signed_message":"canonical_sha256_bytes"},"source_id":"1901.02565","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:bb8fd2aa37c5956ed52a2040f3410218f9761fd8f3577ac3c3f89fc4c6d6c403","sha256:3594e5f7a7b31aea389a02368773e90028f38f75621502aa955b08e3555c98d8"],"state_sha256":"e56ec9283de5b4920f2d47b54d83d5119bb39cb769f96915f4640774d76a6825"}
