In group recommendation, the core is to design preference aggregation functions to obtain a quality summary of all group members' preferences. Such user and group preferences are commonly represented as points in the vector space (i.e., embeddings), where multiple user embeddings are compressed into one to facilitate ranking for group-item pairs. However, the resulted group representations, as points, lack adequate flexibility and capacity to account","authors_text":"Hongzhi Yin, Jing Long, Meng Wang, Quoc Viet Hung Nguyen, Tong Chen, Yang Wang","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.IR","submitted_at":"2022-04-06T05:52:08Z","title":"Thinking inside The Box: Learning Hypercube Representations for Group Recommendation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2204.02592","kind":"arxiv","version":3},"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":"sha256:23b03769fad2116c19d7d1bded74cbfd756a3aa02e0a1164b119dbca3fad3e5b","target":"record","created_at":"2026-07-05T05:22:07Z","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":"8687c8d29607bbeda178c392672743afab3c28fb461a721281042c5ee786bc82","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.IR","submitted_at":"2022-04-06T05:52:08Z","title_canon_sha256":"3e00574048207bbfc6b0d77f61939467d816a78f4a4c9d6791dc398ee4ff24e7"},"schema_version":"1.0","source":{"id":"2204.02592","kind":"arxiv","version":3}},"canonical_sha256":"d1f6cf456e298e59737b4f311280d55b11aa191507e5e05548ede84724c6434e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d1f6cf456e298e59737b4f311280d55b11aa191507e5e05548ede84724c6434e","first_computed_at":"2026-07-05T05:22:07.152747Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:22:07.152747Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"LuCmZOKV/cv5yqX7s3Vvgwi9sJRp3nKpr93DzdYCB6635ADURnaVEabZ+n8aMSIX13GRXNgx9I2/52jaQA+zBQ==","signature_status":"signed_v1","signed_at":"2026-07-05T05:22:07.153149Z","signed_message":"canonical_sha256_bytes"},"source_id":"2204.02592","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:23b03769fad2116c19d7d1bded74cbfd756a3aa02e0a1164b119dbca3fad3e5b","sha256:e392013c403097de5fa01d5f96e70a2e7aa3a47159ed04cea6ecc40e02657665"],"state_sha256":"36fa1fc1e423f7fb42477296e2ea4432cee8a4d2e2488e076e2d3ae073e55f19"}
