Quantization-aware distillation (QAD) helps recover accuracy lost under low bit quantization by training a quantized student to match the output distribution of a frozen higher precision teacher via a KL-divergence loss. In this work, we first provide a representation level diagnosis of QAD: output matching alone can mask internal degradation, because many intermediate activation geometries can yield similar ","authors_text":"Chi Liu, Fangbo Tu, Haifeng Wu, Jian Wan, Junhua Zhao, Srinivasan Manoharan, Xin Chen","cross_cats":["cs.LG"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.AI","submitted_at":"2026-06-04T04:03:42Z","title":"Beyond Output Matching: Preserving Internal Geometry in NVFP4 LLM Distillatio"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2606.05682","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":"sha256:6345d86e50273ea1983d65a2753365e91381b20444d5967b7a43e2fb2088254e","target":"record","created_at":"2026-06-05T01:14:59Z","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":"9b59e0dfc22e300ed042453b9ddd711858151b9ee80580d756d11bc214b43ebe","cross_cats_sorted":["cs.LG"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.AI","submitted_at":"2026-06-04T04:03:42Z","title_canon_sha256":"e406525cd53e0f858621ffc7addfde4cbbdcd17657f8d2454f7908d79050caec"},"schema_version":"1.0","source":{"id":"2606.05682","kind":"arxiv","version":1}},"canonical_sha256":"4a192fbedc7656a72c8b8206d5a2e330b3b9c83a6fe7b0b2e68125ee4352f492","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4a192fbedc7656a72c8b8206d5a2e330b3b9c83a6fe7b0b2e68125ee4352f492","first_computed_at":"2026-06-05T01:14:59.170981Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-05T01:14:59.170981Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Dsw+wpLPNvp6eKcovGb+EruEnGgwnUlujMSA1ePLie4XSsiVHeunwfPzydSJsFEFoFeKEKO8lQc/SD8aqHVxDA==","signature_status":"signed_v1","signed_at":"2026-06-05T01:14:59.171410Z","signed_message":"canonical_sha256_bytes"},"source_id":"2606.05682","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6345d86e50273ea1983d65a2753365e91381b20444d5967b7a43e2fb2088254e","sha256:994f6effc8b21663ed9461304afa1ae60d6812c857cee7c4f3c8b64bb17825f0"],"state_sha256":"7bbf7c474032010698d0a3008a4fc5a118c08c8bc0f1b7def4dec0e17076c72a"}
