However, the high computational requirements to fine-tune these LLMs on downstream tasks pose significant challenges, particularly when resources are limited. In response to this challenge, we introduce L1RA, a novel technique aimed at dynamically distributing the rank of low-rank adapters during fine-tuning using LoRA. Given a rank budget (i.e., total sum of adapters rank), L1RA leverages L1 regularisation to prune redundant ranks and redistribute them across a","authors_text":"Mark James Carman, Nicolo Brunello, Raul Singh, Vincenzo Scotti","cross_cats":["cs.PF"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CL","submitted_at":"2025-09-05T08:03:01Z","title":"L1RA: Dynamic Rank Assignment in LoRA Fine-Tuning"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2509.04884","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:ef7f8940e53aa4eec871a2c6c3a6e91277099ef576b776998143119af4a00777","target":"record","created_at":"2026-07-05T12:05:31Z","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":"02d6f370225c4ce36698fbc51bb29e979ced6edee69e398f87f55ff12a4ff437","cross_cats_sorted":["cs.PF"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CL","submitted_at":"2025-09-05T08:03:01Z","title_canon_sha256":"aff70c221b411a325a16414c8d8ff4039de67b87d2d1b069b19f8713270de045"},"schema_version":"1.0","source":{"id":"2509.04884","kind":"arxiv","version":1}},"canonical_sha256":"32945b00150a918b43d0be66abe41f8ed2a5b40982e7a4b9e580ff9b07ad684b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"32945b00150a918b43d0be66abe41f8ed2a5b40982e7a4b9e580ff9b07ad684b","first_computed_at":"2026-07-05T12:05:31.602682Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T12:05:31.602682Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"E5H/aUWB7pKSzw0Q/6hT1I2E0MznT+uW5xAeS0FDxAh7MgiK2kllmsPKjfx2lVvVfZhLIWHKYQX/gR9xfd+7CQ==","signature_status":"signed_v1","signed_at":"2026-07-05T12:05:31.603184Z","signed_message":"canonical_sha256_bytes"},"source_id":"2509.04884","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ef7f8940e53aa4eec871a2c6c3a6e91277099ef576b776998143119af4a00777","sha256:d0ee9d570317143159f6091ce3d048a3c87e75da853eb75258d62bb6ad661516"],"state_sha256":"7aaf09018e38f13214ca1af6a77ec20d05fab3943b2ce1e96f2f91793fa378d4"}
