However, designing effective recommender systems faces the key challenges: the exploration-exploitation tradeoff in securing incentive to explore new products against user's self-interested preferences. While prior work addresses Bayesian Incentive Compatibility (BIC) in fixed-design linear bandits (Sellke & Slivkins, 2023), we tackle the challenge of stochastic user covariates sampled online. Unlike standard black-box reductions (Mansour et al., 2020), our two-stage framework exploits the","authors_text":"Guang Cheng, Xiaowu Dai, Yuantong Li","cross_cats":["cs.GT","cs.LG","stat.ML"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IR","submitted_at":"2024-06-04T23:46:10Z","title":"Incentivized Exploration with Stochastic Covariates: A Two-Stage Mechanism Design for Recommender System"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2406.04374","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":"sha256:3af02d7d902a91dcaf000b9ecc985af9aada49f25ba3a0ed2ab7dae321c56b27","target":"record","created_at":"2026-05-26T02:03:46Z","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":"0afbb56d706d14ae912c3c4da8decd2753b10d6444231849418a0c6c4d0178d6","cross_cats_sorted":["cs.GT","cs.LG","stat.ML"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IR","submitted_at":"2024-06-04T23:46:10Z","title_canon_sha256":"b6cdf4cc612535439b9b2d5063046a987b9bd0ac2f8b7dd6f771fa03b2d39516"},"schema_version":"1.0","source":{"id":"2406.04374","kind":"arxiv","version":2}},"canonical_sha256":"71076b2598865dd7a2b1f355d605a5b23bfc52701bed6a747e2ba5d44f9fb5a2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"71076b2598865dd7a2b1f355d605a5b23bfc52701bed6a747e2ba5d44f9fb5a2","first_computed_at":"2026-05-26T02:03:46.115020Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-26T02:03:46.115020Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"HJEygYscealto+yjkiKgSdNv2lW8jR/hJ6DwJfktFGSqkpWg5wXTsia5Qs3VSQX2vQhI6aJbopFPvse7qQv5Dw==","signature_status":"signed_v1","signed_at":"2026-05-26T02:03:46.115632Z","signed_message":"canonical_sha256_bytes"},"source_id":"2406.04374","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3af02d7d902a91dcaf000b9ecc985af9aada49f25ba3a0ed2ab7dae321c56b27","sha256:8ca199690b1df9fee3525565db5f911761215ef1e0552413409ae637ddae1e46"],"state_sha256":"726bdeaa2e11f603a963c946d383dc922e793fe7fcf7846356a835c89557287d"}
