DataDignity: Training Data Attribution for Large Language Models

cs.AI · 2026-05-07 · unverdicted · novelty 7.0

ScoringModel raises mean Recall@10 to 52.2 on the FakeWiki provenance benchmark from 35.0 for the best baseline, winning 41 of 45 model-by-condition comparisons and gaining 15.7 points on jailbreak-style queries.

LoRA: Low-Rank Adaptation of Large Language Models

cs.CL · 2021-06-17 · accept · novelty 7.0

Adapting large language models by training only a low-rank decomposition BA added to frozen weight matrices matches full fine-tuning while cutting trainable parameters by orders of magnitude and adding no inference latency.

Combining pre-trained models via localized model averaging

stat.ME · 2026-05-13 · unverdicted · novelty 6.0

Localized model averaging with covariate-dependent weights achieves asymptotic optimality and weight consistency for combining pre-trained models under a general loss framework.

TLoRA: Task-aware Low Rank Adaptation of Large Language Models

cs.CL · 2026-04-20 · unverdicted · novelty 6.0

TLoRA jointly optimizes LoRA initialization via task-data SVD and sensitivity-driven rank allocation, delivering stronger results than standard LoRA across NLU, reasoning, math, code, and chat tasks while using fewer trainable parameters.

HyperAdapt: Simple High-Rank Adaptation

cs.LG · 2025-09-23 · unverdicted · novelty 6.0

HyperAdapt performs parameter-efficient fine-tuning by row- and column-wise diagonal scaling to induce high-rank updates with only n+m trainable parameters.

LoCO: Low-rank Compositional Rotation Fine-tuning

cs.LG · 2026-05-15 · unverdicted · novelty 5.0

LoCO is a PEFT technique that constructs orthogonal transformations via low-rank skew-symmetric matrices and compositional rotation chains with a parallelizable approximation, validated on transformer adaptations.

Training Transformers in Cosine Coefficient Space

cs.PF · 2026-04-06 · unverdicted · novelty 5.0

Training transformers by optimizing only half the DCT coefficients per linear layer achieves validation loss within 0.024 of a dense baseline on Shakespeare character prediction, outperforming matched-parameter LoRA due to preserved rank flexibility.
