A common assumption adopted in the literature is that the realized (ground truth) reward by taking the selected action is observed by the learner at no cost, which, however, is not realistic in many practical scenarios. When observing the ground truth reward is costly, a key challenge for the learner is how to judiciously acquire the ground truth by assessing the benefits and costs i","authors_text":"Jie Xu, Linqi Song","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2017-01-24T04:12:25Z","title":"A Contextual Bandit Approach for Stream-Based Active Learning"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1701.06725","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:d15a199db99142b29e7ceed86952fb4a09faadd24ee13734b2e0d0b79346d240","target":"record","created_at":"2026-05-18T00:52:12Z","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":"e89d5bae24ae63c584657e718a1b7b7d8dcaf4ea93a078e0e293b4476e641ad3","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2017-01-24T04:12:25Z","title_canon_sha256":"9ca1ea88cb3305480daea96fa9875051ee1579e26c5c93b5051feb83c59f8098"},"schema_version":"1.0","source":{"id":"1701.06725","kind":"arxiv","version":1}},"canonical_sha256":"327c430d077c5081a8634c29220873108c40e19d780ed322fd857bd3c5687785","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"327c430d077c5081a8634c29220873108c40e19d780ed322fd857bd3c5687785","first_computed_at":"2026-05-18T00:52:12.304608Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:52:12.304608Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"VfdSXOtW9v6Nor2w9bXIaesk4kPJTncQZGCkgd9t9gCCM4zGaWnhKY/CuiU+abG7dd9E8bqJ4CBuwXvmVi7yCw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:52:12.305019Z","signed_message":"canonical_sha256_bytes"},"source_id":"1701.06725","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d15a199db99142b29e7ceed86952fb4a09faadd24ee13734b2e0d0b79346d240","sha256:81819deff0b1520f2513710de2a729fe3c353ba181b5092bc3accd8379109f7e"],"state_sha256":"2be8b2316f2ee0f181b86055b199e514d3a1884d0c44ceacf117d5ca532d98a6"}
