Self-supervised speech models offer rich multi-layer representations, yet existing approaches either use a single layer or fuse all layers indiscriminately, and only reveal layer importance after training.\n  We propose a model-agnostic, two-stage methodology that identifies informative depth zones before any task-specific model is trained. In the first stage, lightweight XGBoost probes evaluate each transformer layer's cross-domain discriminat","authors_text":"Bo Chen, Majid Rostami, Marjan Beheshti","cross_cats":["eess.AS"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.SD","submitted_at":"2026-06-29T18:19:37Z","title":"Probing-Guided Layer Selection from Self-Supervised Speech Models for Generalizable Audio Deepfake Detection"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2606.30791","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":"sha256:85f44d6ef0827283f5b7fe3112f9f7410728c869ebc64f8f5c6f22678eaa5573","target":"record","created_at":"2026-07-01T00:17:17Z","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":"1937595c26649a429fe8c987460d1ab0bc4a30358fbc34deae61c77e55beb156","cross_cats_sorted":["eess.AS"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.SD","submitted_at":"2026-06-29T18:19:37Z","title_canon_sha256":"9b3b54bdae6bb9420bad5be6a8aa3457f2338e7789669cc6b7390ba8a4e520fe"},"schema_version":"1.0","source":{"id":"2606.30791","kind":"arxiv","version":1}},"canonical_sha256":"7ae9728100db1cf394aa93fe0417601e56158a334f50d9adecdf36f74f199a47","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7ae9728100db1cf394aa93fe0417601e56158a334f50d9adecdf36f74f199a47","first_computed_at":"2026-07-01T00:17:17.066117Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-01T00:17:17.066117Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"+08C0pGyZoyPMJuySXj4d8gOOYsH7kNLOtNcnYDK0xs0AEYYwT6qtSKkQ5cm6dMHqXAJrnqzZngj9cN8u3jEAQ==","signature_status":"signed_v1","signed_at":"2026-07-01T00:17:17.066583Z","signed_message":"canonical_sha256_bytes"},"source_id":"2606.30791","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:85f44d6ef0827283f5b7fe3112f9f7410728c869ebc64f8f5c6f22678eaa5573","sha256:b3bc4f8bb3f7e70ed295a3a381b83d198f13b261b87469c315d4ac4e5c8be05a"],"state_sha256":"a8a89687a1b3711304ba78b27c0c16aebc4efa90f1f4273e92cbe360e56274fd"}
