The Pitman-Yor process, a generalization of Dirichlet process, provides a tractable prior distribution over the space of countably infinite discrete distributions, and has found major applications in Bayesian non-parametric statistics and machine learning. Here we show that it also provides a natural family of priors for Bayesian entropy estimation, due to the fact that moments of the induced posterior distribution over $H$ can be ","authors_text":"Evan Archer, Il Memming Park, Jonathan Pillow","cross_cats":["math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2013-02-02T01:04:11Z","title":"Bayesian Entropy Estimation for Countable Discrete Distributions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1302.0328","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:fff582cf7fa64df620f279ef3c4682b35e6dfdc9cd268821ed27e5ded45e9f5f","target":"record","created_at":"2026-05-18T02:54:30Z","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":"551c3a36bd906d426ccadf481eae5429b7c74689eec1172515dd9b2f137504a1","cross_cats_sorted":["math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2013-02-02T01:04:11Z","title_canon_sha256":"38f16cb1dddc5c3ad018765158e5ddcd2d7eb8f1c9ceb5abb544d7e5b40b4f3d"},"schema_version":"1.0","source":{"id":"1302.0328","kind":"arxiv","version":3}},"canonical_sha256":"ceec325c6c73d006bb7840ecaa8486b383500ebd2b1453a67ccd30866f039735","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ceec325c6c73d006bb7840ecaa8486b383500ebd2b1453a67ccd30866f039735","first_computed_at":"2026-05-18T02:54:30.856180Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:54:30.856180Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"/dfYvT30M5rjWMGNLN/50rK31r7ixKI1Kg2913oBSQvN0uviW7q6W0O6LswCmnIMUg3/MWKzvrzlLAhy16e+CA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:54:30.856681Z","signed_message":"canonical_sha256_bytes"},"source_id":"1302.0328","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:fff582cf7fa64df620f279ef3c4682b35e6dfdc9cd268821ed27e5ded45e9f5f","sha256:8b544d1f4c7e03f93faf7fc27ed122408c81a28cb4f50e22504af0f598e0f540"],"state_sha256":"8bd1544855c055836f23c0b1abeb5ab9d2b1a964686486017b31c8a346e00f69"}
