Each student provides a partial ranking of the courses taken throughout his or her undergraduate career. We compute pairwise rank comparisons between courses based on the order students typically take them, aggregate the results over the entire student population, and then obtain a proxy for the rank offset between pairs of courses. We extract a global ranking of the courses via several state-of-the art algorithms for ranking with pairwise noisy information, including Se","authors_text":"Charlie Marshak, Dillon Montag, Mihai Cucuringu, Puck Rombach","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by-sa/4.0/","primary_cat":"cs.LG","submitted_at":"2016-03-03T17:29:03Z","title":"Rank Aggregation for Course Sequence Discovery"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1603.02695","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":"sha256:1bb405e9ed46f4a593152b7d4045cae419063133a328d6f50ab3ecce5b824d72","target":"record","created_at":"2026-05-18T01:19:20Z","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":"714d7c0f8a2d0c5f51c8433e95f7df5823ea3b497ee7d2f6c611acd40eb06d6b","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by-sa/4.0/","primary_cat":"cs.LG","submitted_at":"2016-03-03T17:29:03Z","title_canon_sha256":"18bfcb847f67472eac6bb3f32845775ee22645a8b35bd6c91a9ce5db7bd5d950"},"schema_version":"1.0","source":{"id":"1603.02695","kind":"arxiv","version":1}},"canonical_sha256":"d02c4316bc25d9b2b4e14ea6ec476e2b5e57dcc047d96eb5e5e5a4f71af30113","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d02c4316bc25d9b2b4e14ea6ec476e2b5e57dcc047d96eb5e5e5a4f71af30113","first_computed_at":"2026-05-18T01:19:20.020859Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:19:20.020859Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"00uBDh4/jwWKUKlFn9Js5AUgXZA6J/oR11Y2ma+58F0/7zITRc84IZBDtW3E8SRBNcFdUA6yVEvNhmxHekoCBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:19:20.021340Z","signed_message":"canonical_sha256_bytes"},"source_id":"1603.02695","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1bb405e9ed46f4a593152b7d4045cae419063133a328d6f50ab3ecce5b824d72","sha256:424b9cd355b8540d1738b9054e7553684f96576f7c0d94bd739a061c63afcd90"],"state_sha256":"d7dd96756fe6abf2c0955c95550b054c33d3d922f79dcf774b2119c7c4637918"}
