Usually, raw data from such storage sites can hardly be described by theoretical statistical distributions since only very limited data is available. Hence, exact information on distribution shapes for all uncertain parameters is very rare in realistic applications. We discuss and compare four different methods tested for data-driven uncertainty quantification based on a benchmark scenario of carbon dioxide stora","authors_text":"Andrea Barth, Bernard Haasdonk, Christian Rohde, Dirk Pfl\\\"uger, Dominik Wittwar, Fabian Franzelin, Gabriele Santin, Ilja Kr\\\"oker, Markus K\\\"oppel, Sergey Oladyshkin, Wolfgang Nowak","cross_cats":["cs.NA","math.NA"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CE","submitted_at":"2018-02-08T22:27:38Z","title":"Comparison of data-driven uncertainty quantification methods for a carbon dioxide storage benchmark scenario"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1802.03064","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:efe3678443376ab09e95c2a3e580d6be15f356b5da5ddee7d2ae6ca7a6cfbd47","target":"record","created_at":"2026-05-18T00:01:09Z","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":"f13443ad213411b10a67a15558320f44b8839c4f5135814b41d88db8278b001e","cross_cats_sorted":["cs.NA","math.NA"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CE","submitted_at":"2018-02-08T22:27:38Z","title_canon_sha256":"3a69e09bf66a915caca810368901d0826712221ac4300dfc69341c980a917708"},"schema_version":"1.0","source":{"id":"1802.03064","kind":"arxiv","version":1}},"canonical_sha256":"e3e1952ca5cdff20b7b43e67658123b40c338a2fe5c94fc7a6441d117bf79fe3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e3e1952ca5cdff20b7b43e67658123b40c338a2fe5c94fc7a6441d117bf79fe3","first_computed_at":"2026-05-18T00:01:09.848335Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:01:09.848335Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"3QsNampYtCu+kPloEpqNt63ObffgIgBySm3z+bHt5V4vm92qDQnUJdVlOspqWSLKN9r9gcsYmRzOa21SRkZACA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:01:09.849013Z","signed_message":"canonical_sha256_bytes"},"source_id":"1802.03064","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:efe3678443376ab09e95c2a3e580d6be15f356b5da5ddee7d2ae6ca7a6cfbd47","sha256:586df3bc428feabe17d1eab187c31b9dd60d82373a0a2a52a650454ec6cadfa4"],"state_sha256":"0d52fd6c86cb75b71c9e2f4842900d1241d80cc91fbf58f1da95cf78c20940b8"}
