Through theoretical analysis, we demonstrate that the fine-tuned result of LoRA is highly sensitive to initialization, which is likely to lead suboptimal low-rank results. While this issue can be mitigated by adjusting the initial direction towards the main singular vectors of the target $\\Delta W$, which is, however, typically unknown in real-world scenarios. To approximate this initial direction, we propose High-Rank Preheating (HRP), which first trains LoRA with a higher preheating rank for a few steps, t","authors_text":"Dacheng Tao, Li Shen, Shi Fu, Xinmei Tian, Yingjie Wang, Yongcheng Jing, Yuzhu Chen","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2025-02-11T17:59:35Z","title":"HRP: High-Rank Preheating for Superior LoRA Initialization"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2502.07739","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:d95875f24b9e4f7e6e298a75efaf9ac46c6d4de5b581d3b995f122b76e55900f","target":"record","created_at":"2026-07-05T11:09:08Z","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":"58c721dd080ec5582140f62b3e17388c6d0821ee0072c40470eeaeadb65fc8d6","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2025-02-11T17:59:35Z","title_canon_sha256":"371e69bd572a6a7314cd970acbdc915cde910052beedc3981e7470deb8501410"},"schema_version":"1.0","source":{"id":"2502.07739","kind":"arxiv","version":3}},"canonical_sha256":"92a103853944891a5d2d2aebbf12e89610633bb1269d34a692e38cd0210f3fb0","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"92a103853944891a5d2d2aebbf12e89610633bb1269d34a692e38cd0210f3fb0","first_computed_at":"2026-07-05T11:09:08.054112Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:09:08.054112Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"fWih+Tky+gwRiivzYnLXfP5r5nk/VQ9Gyno8CNbMonu+UtLbmGx0ry58JzTdaGiVUdeLOEzqWhg3A80i04CmDQ==","signature_status":"signed_v1","signed_at":"2026-07-05T11:09:08.054594Z","signed_message":"canonical_sha256_bytes"},"source_id":"2502.07739","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d95875f24b9e4f7e6e298a75efaf9ac46c6d4de5b581d3b995f122b76e55900f","sha256:b32fc592527838c6f364bbca70ea7f9bc78858962e6175cbaf1ed6f8b8f43971"],"state_sha256":"c7d541e6537bb91d51f2e7c619a5bbd10a0cc445d288da37f90f774e73c21f98"}
