Typically, the observation noise is assumed to be independent of the evaluation point and to satisfy a tail bound uniformly on the domain; a restrictive assumption for many applications. In this work, we consider bandits with heteroscedastic noise, where we explicitly allow the noise distribution to depend on the evaluation point. We show that this leads to new trade-offs for information and regret, which are not taken into account by existing approaches like upper confidence boun","authors_text":"Andreas Krause, Johannes Kirschner","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ML","submitted_at":"2018-01-29T18:52:38Z","title":"Information Directed Sampling and Bandits with Heteroscedastic Noise"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1801.09667","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":"sha256:96d9386c869500cc2be83cb7b4b479be8038160bca3a69b8a5e9b69d95289feb","target":"record","created_at":"2026-05-18T00:18:03Z","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":"629f74f72f1c142718d04b353cd758f1844dcdf68cff4bddd039dc379fb68cf4","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ML","submitted_at":"2018-01-29T18:52:38Z","title_canon_sha256":"be6fddfaed10768a83a833f499f744814a197faba8e6795a94db7ec6c794dad6"},"schema_version":"1.0","source":{"id":"1801.09667","kind":"arxiv","version":2}},"canonical_sha256":"58ae4916ac80909108afa09d58efa3b3753e64bdf70a0509b330c6a77430cf66","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"58ae4916ac80909108afa09d58efa3b3753e64bdf70a0509b330c6a77430cf66","first_computed_at":"2026-05-18T00:18:03.792223Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:18:03.792223Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"pJRAFZdTbxcoWQisw2rjR71Soq0Gwsc8znP20aTY/5ihMyxPwzySNMD/JQ1QsPZrn2aBmpGDsK96AxU4kUkPAQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:18:03.792828Z","signed_message":"canonical_sha256_bytes"},"source_id":"1801.09667","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:96d9386c869500cc2be83cb7b4b479be8038160bca3a69b8a5e9b69d95289feb","sha256:3cceb92990254b29577d3580f206f4281e9645fe963d0edb505e04b8b0fd309e"],"state_sha256":"b81e73e4490f97659d5a3b7e29ecfbbfd9caa3442bd8470c3b17336ab30db745"}
