Projected Gradient Descent (PGD) is one of the most effective and conceptually simple algorithms to generate such adversaries. The search space of PGD is dictated by the steepest ascent directions of an objective. Despite the plethora of objective function choices, there is no universally superior option and robustness overestimation may arise from ill-suited objective selection. Driven by this observation, we postulate that the combination of different objectives thro","authors_text":"Alexandros Potamianos, Efthymios Georgiou, Nikolaos Antoniou","cross_cats":["cs.CR","cs.CV"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2022-12-15T17:44:31Z","title":"Alternating Objectives Generates Stronger PGD-Based Adversarial Attacks"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2212.07992","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":"sha256:67ec8d230a9f2fe84f8077daf8e3a51f5527e7d5f533b3c9fcd08707d603f045","target":"record","created_at":"2026-07-05T05:25:39Z","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":"259e29d095d28faead431e879eea1ddd0539a97cb4e41ec49888ed384d4e30bb","cross_cats_sorted":["cs.CR","cs.CV"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2022-12-15T17:44:31Z","title_canon_sha256":"533a5ec806318879952050f5c448621c88f511c6397ee4c0e0389a4fc3922763"},"schema_version":"1.0","source":{"id":"2212.07992","kind":"arxiv","version":1}},"canonical_sha256":"ac32b7aba3ea8330766815c153537f95602ecb086d5306a8c5ff941f0cd9c512","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ac32b7aba3ea8330766815c153537f95602ecb086d5306a8c5ff941f0cd9c512","first_computed_at":"2026-07-05T05:25:39.679577Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:25:39.679577Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"p8euJ3NICVz0xlqEhJTnA0THAfqNGZOu2VK4xkPsxlMTWpv8DjxT512QQuQAdpfzN5eRdJWE//rwEACCEUInBg==","signature_status":"signed_v1","signed_at":"2026-07-05T05:25:39.680010Z","signed_message":"canonical_sha256_bytes"},"source_id":"2212.07992","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:67ec8d230a9f2fe84f8077daf8e3a51f5527e7d5f533b3c9fcd08707d603f045","sha256:2db13f82ab3166d657df68e9a50e2c79ab519e1d504f63b1121167bfdb84b423"],"state_sha256":"12fb9b00ddd52e1b01dac3e87463dcea2d1354998f88337cd324611a198b6c70"}
