The approach is based on some important properties of the GPTs and new invariants. A new shape representation is given and numerically tested in the presence of measurement noise. The stability and resolution of the proposed identification algorithm is numerically quantified.","authors_text":"Habib Ammari, Han Wang, Hy{\\oe}nb{\\ae} Kang, Josselin Garnier, Thomas Boulier, Wenjia Jing","cross_cats":["math-ph","math.AP","math.MP","math.NA"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.OC","submitted_at":"2012-04-13T16:00:20Z","title":"Target Identification Using Dictionary Matching of Generalized Polarization Tensors"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1204.3035","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:b9069e0e1a1badf7be47b660e1f5a74ca47f6a3b1aaaf49da026af97eba5c229","target":"record","created_at":"2026-05-18T03:32:31Z","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":"75dada20a9a3c984019cb633aa8955b491c5aec52f221f0f01cca97d198b0165","cross_cats_sorted":["math-ph","math.AP","math.MP","math.NA"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.OC","submitted_at":"2012-04-13T16:00:20Z","title_canon_sha256":"b58d9a69818eea9ea9dc40f06574c780f02040908fa1c90d4f2dd74ac3615324"},"schema_version":"1.0","source":{"id":"1204.3035","kind":"arxiv","version":2}},"canonical_sha256":"316270c078703fa69bd11b7059927b01adc2060349df041dfa5b38f7cc6b795f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"316270c078703fa69bd11b7059927b01adc2060349df041dfa5b38f7cc6b795f","first_computed_at":"2026-05-18T03:32:31.841552Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:32:31.841552Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"kImed9ywAyWtgNj2ZsCORvjP4bO+2OAqB932TX03a29REhVD6zpayWRg/wLNK/5oF9OzcTavfv0s3LITIYX1Bw==","signature_status":"signed_v1","signed_at":"2026-05-18T03:32:31.842141Z","signed_message":"canonical_sha256_bytes"},"source_id":"1204.3035","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b9069e0e1a1badf7be47b660e1f5a74ca47f6a3b1aaaf49da026af97eba5c229","sha256:bff8cbbb2ccf99356a229f43eb6bc35c353b88d6187730362a049f23b39e4729"],"state_sha256":"b29c74fa75c3ea06c09cba05b94a7988b0938276063de936a5e78ba0d1aa9367"}
