However in many instances we may not have a Hamiltonian or good information about the degrees of freedom (or, in a roughly complementary sense, the redundancies in observed data), but on the other hand we have access to a preponderance of raw data. The development outlined here is an attempt to apply the principles of thermodynamics and statistical mechanics generically to such cases.","authors_text":"David Ford","cross_cats":["cond-mat.other","nlin.CG","physics.data-an"],"headline":"","license":"","primary_cat":"cond-mat.stat-mech","submitted_at":"2004-02-12T01:26:01Z","title":"Application of Thermodynamics to the Reduction of Data Generated by a Non-Standard System"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"cond-mat/0402325","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":"sha256:1fc70fc20b2400b058776e412c6ec0181cdc751cd5638393b2350f5e0c6a2088","target":"record","created_at":"2026-07-04T14:49:38Z","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":"dcaaf10ee6fce83948619bccb272888a4398e3b8cdd7327d3bb82cb3aedc1fc7","cross_cats_sorted":["cond-mat.other","nlin.CG","physics.data-an"],"license":"","primary_cat":"cond-mat.stat-mech","submitted_at":"2004-02-12T01:26:01Z","title_canon_sha256":"9d30700883087e57ae741a3fba8813f5ac1b415b89577656faf817383a3290b7"},"schema_version":"1.0","source":{"id":"cond-mat/0402325","kind":"arxiv","version":1}},"canonical_sha256":"33f759614b69c87e6b5751200e7f9174464c9cfd5e0c22ba03774b4574de1899","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"33f759614b69c87e6b5751200e7f9174464c9cfd5e0c22ba03774b4574de1899","first_computed_at":"2026-07-04T14:49:38.436089Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T14:49:38.436089Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"wCWkwjCiMPnflNfDizFMvJK6rdlhYdhJu7RBLq6pPTMFstcEP347g546F4zTK3B3V7MtgK/ytHYv0OZIKro6CQ==","signature_status":"signed_v1","signed_at":"2026-07-04T14:49:38.436496Z","signed_message":"canonical_sha256_bytes"},"source_id":"cond-mat/0402325","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1fc70fc20b2400b058776e412c6ec0181cdc751cd5638393b2350f5e0c6a2088","sha256:1be3d107dcfda2b656b5417e3e923a003543024005ceb9529fd2db516f1a340d"],"state_sha256":"d71f87d6aeae1e5904d191d7ecde33ba983d24809e40dcea64b2b46d36b24eb4"}
