In our contribution to this discussion, we argue for a probe metric that reflects the fundamental trade-off between probe complexity and performance: the Pareto hypervolume. To measure complexity, we present a number of parametric and non-parametric metrics. Our experiments using Pareto hypervolume as an evaluation metric show that probes often do not conform to our expectations -- e.g., why should the n","authors_text":"Adina Williams, Naomi Saphra, Ryan Cotterell, Tiago Pimentel","cross_cats":["cs.LG"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2020-10-05T17:27:31Z","title":"Pareto Probing: Trading Off Accuracy for Complexity"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2010.02180","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":"sha256:814c66a65bec0df0b87d56234b2d3126997745887e99d34c1047b462e88d7525","target":"record","created_at":"2026-07-05T07:19:39Z","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":"97af3e60539b03a9054f68a80633c36311543690bb3069cc7c7f551a9510621e","cross_cats_sorted":["cs.LG"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2020-10-05T17:27:31Z","title_canon_sha256":"3f1a6d67cc803f4d359319609b44a05cd581f585728d54ef10f2cb7acea68a87"},"schema_version":"1.0","source":{"id":"2010.02180","kind":"arxiv","version":3}},"canonical_sha256":"45bb1218588b681ed350ab10666449c68c68cbccffbd8b62a923817df31a5ca5","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"45bb1218588b681ed350ab10666449c68c68cbccffbd8b62a923817df31a5ca5","first_computed_at":"2026-07-05T07:19:39.883126Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T07:19:39.883126Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"MDKaa0C6+ElJVz9sQRRcqDtkUEK5I/NReCoIGtOH/pH694188HNT8baJkjocIlP4sDi2ea/mkZ4spjtxs89CAw==","signature_status":"signed_v1","signed_at":"2026-07-05T07:19:39.883622Z","signed_message":"canonical_sha256_bytes"},"source_id":"2010.02180","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:814c66a65bec0df0b87d56234b2d3126997745887e99d34c1047b462e88d7525","sha256:39d3b24de7499beb833b8a5684590fb4a811b90a74b457d3cd869e5fa12b32de"],"state_sha256":"2b15e0e7bc84b4b1af38cc3775a8e47073f5d8a0ff53fe3a67f178c438783285"}
