In this paper, we derive an alternative variational lower bound from the one common in VAEs, which aims to minimize aggregate information loss. Using our lower bound as the objective function for an auto-encoder enables us to place a prior on the bulk statistics, corresponding to an aggregate posterior for the entire dataset, as opposed to a single sample posterior as in the original VAE. This alternative form of prior constraint allows i","authors_text":"Niki Trigoni, Robert Birke, Ronald Clark, Shuyu Lin, Stephen Roberts","cross_cats":["stat.ML"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2019-02-16T21:20:48Z","title":"WiSE-ALE: Wide Sample Estimator for Approximate Latent Embedding"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1902.06160","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:ef81c5cc32213d94e4007108f341cd78d6111f060b905cba11e74d5a7b91c8f1","target":"record","created_at":"2026-05-17T23:50:55Z","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":"aa12d2ef80b9cd9e8a32b6eb515a7792f8f003bbe9a600c7887077fc33b3978f","cross_cats_sorted":["stat.ML"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2019-02-16T21:20:48Z","title_canon_sha256":"fd6e393aa42ddac3c75e99a66f4ab6d9c2b50bbeeaeeb649795aced0f82edea4"},"schema_version":"1.0","source":{"id":"1902.06160","kind":"arxiv","version":3}},"canonical_sha256":"9fe4781438c6380f7f246f34407baf85cd81bf1ced9ff3e04e036681d30d1f81","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9fe4781438c6380f7f246f34407baf85cd81bf1ced9ff3e04e036681d30d1f81","first_computed_at":"2026-05-17T23:50:55.622701Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:50:55.622701Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"+NhYR5r6vKasn7u8BPaqtG1zVzPpV7lo1+ypqOW0PSMcVqLdMtVV8ciSF1N5szS+MH4ythATJ5fu13MdfrCtCg==","signature_status":"signed_v1","signed_at":"2026-05-17T23:50:55.623377Z","signed_message":"canonical_sha256_bytes"},"source_id":"1902.06160","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ef81c5cc32213d94e4007108f341cd78d6111f060b905cba11e74d5a7b91c8f1","sha256:a14526cfa40b2ae562cf2a4e3e2c78d9c1c79d4beaea07776b8fe9fa3184d592"],"state_sha256":"b8dd946cb96a8585c93963298465631dfa6b40046abdcad9a142f6846749ae01"}
