Improving Cross-Format Robustness in Language Models with Multi-Format Training

June M. Liu, Shaomian Zheng, He Cao +3

Large language models often remain sensitive to answer format: a question solved correctly in one form may fail in another semantically equivalent form. To study this gap, we defin…

Measuring language complexity from hierarchical reuse of recurring patterns

Junyi Zhou, Rui Liu, Pengyu Liu +1

We introduce the ladderpath index as a measure of language complexity grounded in algorithmic information theory. It counts the minimum steps needed to reconstruct a sequence throu…

RubricBench: Aligning Model-Generated Rubrics with Human Standards

Qiyuan Zhang, Junyi Zhou, Yufei Wang +8

As Large Language Model (LLM) alignment evolves from simple completions to complex, highly sophisticated generation, Reward Models are increasingly shifting toward rubric-guided ev…

LLaDA-o: An Effective and Length-Adaptive Omni Diffusion Model

Zebin You, Xiaolu Zhang, Jun Zhou +2

We present \textbf{LLaDA-o}, an effective and length-adaptive omni diffusion model for multimodal understanding and generation. LLaDA-o is built on a Mixture of Diffusion (MoD) fra…

GRIP: Geometric Refinement and Adaptive Information Potential for Data Efficiency

Changhao Wang, Jiaolong Yang, Xinhao Yao +7

The performance of Large Language Models (LLMs) is increasingly governed by data efficiency rather than raw scaling volume. However, existing selection methods often decouple globa…

Improving Autoformalization Using Direct Dependency Retrieval

Shaoqi Wang, Lu Yu, Siwei Lou +4

The convergence of deep learning and formal mathematics has spurred research in formal verification. Statement autoformalization, a crucial first step in this process, aims to tran…
