While it has been common practice to use some form of shuffling in DP-SGD implementations, privacy accounting algorithms have typically assumed that Poisson subsampling is used instead. Recent work by Chua et al. (ICML 2024), however, pointed out that shuffling based DP-SGD can have a much larger privacy cost in practical regimes of parameters. In this work we show that the Balls-and-Bins sampling achieves the \"best-of-both\" samplers, namely, the implementation of Balls-and-Bins sampli","authors_text":"Amer Sinha, Badih Ghazi, Charlie Harrison, Chiyuan Zhang, Ethan Leeman, Lynn Chua, Pasin Manurangsi, Pritish Kamath, Ravi Kumar","cross_cats":["cs.CR","cs.DS","stat.ML"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2024-12-21T23:09:14Z","title":"Balls-and-Bins Sampling for DP-SGD"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2412.16802","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:e115908d0c479c69d551cd79a3a8a6d9913d0fe6ce02f31c4bf51b80776307ed","target":"record","created_at":"2026-07-05T10:42:14Z","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":"29b30064bac8962dc79711e766f5987c24ef0e460e2fc6b2879cf8dbcf9b46c3","cross_cats_sorted":["cs.CR","cs.DS","stat.ML"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2024-12-21T23:09:14Z","title_canon_sha256":"f53341c1fd4951161924c5f7d6a18113a5ab7497f729e96705ab4bd99aa05247"},"schema_version":"1.0","source":{"id":"2412.16802","kind":"arxiv","version":2}},"canonical_sha256":"7b998f0fa9e9cdfb45fd023205db48a56f54d0728362afce2c2795547e4c3034","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7b998f0fa9e9cdfb45fd023205db48a56f54d0728362afce2c2795547e4c3034","first_computed_at":"2026-07-05T10:42:14.344071Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:42:14.344071Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"9W5imrJvdh13T6aXT1D+ZTOm2RWqfXOZyuMOHNimeBzjHjyeo0dheHYq6UTKrTaUoT0LkVdbt8eGjCsKa9TcCg==","signature_status":"signed_v1","signed_at":"2026-07-05T10:42:14.344601Z","signed_message":"canonical_sha256_bytes"},"source_id":"2412.16802","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e115908d0c479c69d551cd79a3a8a6d9913d0fe6ce02f31c4bf51b80776307ed","sha256:3aa6e9dde75153a60cc04363268c04896eef8d981581670435ea7f1715b88245"],"state_sha256":"7d6899e5ab08786379ccb0ac143741019d483a47885a50b1bc71ae39ea9f232a"}
