Typically, an iterative procedure is pursued: an approximate model is devised, prescribed experiments are then performed and the resulting data is exploited to refine the model. To help to reduce the cost of trial-and-error approaches, strategies for model-based design of experiments suggest experimental points where the expected gain in information for the model is the largest. It requires the resolution of a large nonlinear, generally nonconvex, optimization problem, whose solution may greatly","authors_text":"Charlie Vanaret, Gleb Karpov, Gleb Ryzhakov, Ivan Oseledets, Jan Schwientek, Michael Bortz, Norbert Asprion, Philipp Seufert","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.OC","submitted_at":"2021-01-22T17:07:11Z","title":"Two-phase approaches to optimal model-based design of experiments: how many experiments and which ones?"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2101.09219","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:c670aedbcfa360af4d6a511b9bd345baf8874d213f7c7555467c70f3c526f844","target":"record","created_at":"2026-07-05T02:08:55Z","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":"85c75d3b2445b170fba79aad3d357853b02d64e8bce0bc4288e4428d58b9fa15","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.OC","submitted_at":"2021-01-22T17:07:11Z","title_canon_sha256":"3af2dc51b294c81cb6f1b98ad68af2ab2940310a77a8183d17e08c212301ed29"},"schema_version":"1.0","source":{"id":"2101.09219","kind":"arxiv","version":1}},"canonical_sha256":"678d2f5425fd1d3a4050a5af996cbac1d740ad0ab4ec4495a45df8ea443a5ee8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"678d2f5425fd1d3a4050a5af996cbac1d740ad0ab4ec4495a45df8ea443a5ee8","first_computed_at":"2026-07-05T02:08:55.260163Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T02:08:55.260163Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"XSwlp5W+r3mAJ3az8S30KhVbzgEDMTLCwJlA/4NYj4MEOEYkms4c8RbIoXNO6d5ScnVGbg6khSidVhBhKbbHAw==","signature_status":"signed_v1","signed_at":"2026-07-05T02:08:55.260560Z","signed_message":"canonical_sha256_bytes"},"source_id":"2101.09219","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c670aedbcfa360af4d6a511b9bd345baf8874d213f7c7555467c70f3c526f844","sha256:8928d7dfd8486dac969849fc86be35e9bf2c1908562a69293a69c598f0caadba"],"state_sha256":"4136f7ae869355d625fab44b6ebf5664b7039eda5f006da01d53568896e8e90c"}
