By utilizing a method grounded on constrained low-rank approximation, our model takes advantage of patients' clinical data and digital interaction data, including browsing and search, to construct patient profiles. As a result of the method, nonnegative embedding vectors are generated, serving as a low-dimensional representation of the patients. Our model was assessed using real-world patient data from a healthcare web portal, with a comprehensive evaluation approach which considered clusterin","authors_text":"Andy Xiang, Barry Drake, Deep Shrestha, Dongjin Choi, Faizan Javed, Haesun Park, Hamid Haidarian, Ozgur Ozturk","cross_cats":["cs.AI"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2023-08-22T19:25:04Z","title":"Patient Clustering via Integrated Profiling of Clinical and Digital Data"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2308.11748","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":"sha256:10d3ea574c7ad5ee5c109388226162464f4f488eb555f63adb590f2eb620dbdf","target":"record","created_at":"2026-07-05T06:43:54Z","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":"fd75613b32b484c7b16ff1cf07734c899eca65f650c7c28b25b87bde49562cb1","cross_cats_sorted":["cs.AI"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2023-08-22T19:25:04Z","title_canon_sha256":"e021d88233cb80703640634d415c7fd6e8af502e4eaae4d70dbcffa617ad508b"},"schema_version":"1.0","source":{"id":"2308.11748","kind":"arxiv","version":1}},"canonical_sha256":"5d263c1584f1f690cffd8e49488472a3a7e635168633da80ec2a5aff8c614eec","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5d263c1584f1f690cffd8e49488472a3a7e635168633da80ec2a5aff8c614eec","first_computed_at":"2026-07-05T06:43:54.419745Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T06:43:54.419745Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"0ybvHzkwGVpGHg7hvYFpr2GgTE9FVLurw5f2kUsCet5PzdCsbDD+m4vBVcr+VcPPHPvlisaW9HV+7xrXeHeqAQ==","signature_status":"signed_v1","signed_at":"2026-07-05T06:43:54.420198Z","signed_message":"canonical_sha256_bytes"},"source_id":"2308.11748","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:10d3ea574c7ad5ee5c109388226162464f4f488eb555f63adb590f2eb620dbdf","sha256:dd8274b89c7d10adeb9a988c6f3bd7364bf1b8576a6f3ca96d96811ceda98a14"],"state_sha256":"3ded5d121c20fe3274a8aba8c2214432bec0e60373cdb263bd0decf619497f5a"}
