Rank Measures of Fine-Tuning Updates Need a Noise Baseline

arXiv cs.LG ↗ · 2026-10-19 Cached

该论文指出,用秩来衡量微更新ΔW时必须加入噪声基线:方向计数类指标显示微更新仅略低于噪声,而稳定秩则显示远低于噪声,二者共同揭示更新具有少数强方向加长尾的结构。研究还发现指令数据、DPO偏好标签对更新并无显著特殊性,并质疑了'后训练是表面性的'相关论断。

Breaking Diffusion: Parallel Reasoning with Draft Refinement

Hugging Face Daily Papers ↗ · 2026-10-19 Cached

The paper introduces Draft Refinement Language Models (DRLMs), which generate complete drafts and iteratively refine them using a single denoiser and a cavity-energy score, outperforming autoregressive and discrete diffusion baselines on Countdown, Sudoku-Extreme, and Maze-Hard with only 6M parameters.

Competing Learning in Hybrid Architectures

Hugging Face Daily Papers ↗ · 2026-10-19 Cached

The paper identifies a Competing Learning phenomenon in hybrid language models where recurrence and attention layers compete to learn the same functions, and proposes a staged training procedure that improves language modeling loss, common-sense reasoning, and retrieval tasks on models up to 1B parameters.

Learning to Read Out: Unembedding Dynamics in Language Model Pretraining

arXiv cs.CL ↗ · 2026-10-16 Cached

论文提出 parameter-trajectory crosscoding 方法,追踪语言模型预训练中 unembedding(读出矩阵)的动态变化,发现模型隐藏状态编码任务信息的时间早于其输出所能表达的时间,早期的行为学时间点可能反映的是读出层的学习而非模型能力的习得。

One Bias Score, Two Factors: How Mitigations Affect Option Bias in Multiple-Choice Evaluation

arXiv cs.CL ↗ · 2026-10-16 Cached

This paper unifies selection bias and order sensitivity in multiple-choice LLM evaluation by showing the pooled selection-rate standard deviation factorizes into flip rate and positional skew. Across 41 checkpoints and 12 benchmarks, it shows prior correction mainly reduces positional skew while ordering aggregation mainly reduces the flip rate, recommending both be reported.

Wrong Votes, Right Gradients: Why Majority-Vote Rewards Track Verifiable RL

arXiv cs.LG ↗ · 2026-10-16 Cached

This paper explains why majority-vote self-rewards match verifiable-reward RL by showing that, at the batch level, incoherent label errors cancel out so the update direction aligns with the gold gradient; it finds error coherence—not error rate—determines when self-generated labels can replace verification.
