ClaHF: A Human Feedback-inspired Reinforcement Learning Framework for Improving Classification Tasks

Tianxiang Xu, Xiaoyan Zhu, Xin Lai +1

Text classification models are typically trained via supervised fine-tuning (SFT). However, SFT essentially performs behavior cloning from instance-wise labels and thus fails to ad…

Making Every Head Count: Sparse Attention Without the Speed-Performance Trade-off

Mingkuan Zhao, Wentao Hu, Jiayin Wang +5

The design of Large Language Models (LLMs) has long been hampered by a fundamental conflict within their core attention mechanism: its remarkable expressivity is built upon a compu…

Mosaic Pruning: A Hierarchical Framework for Generalizable Pruning of Mixture-of-Experts Models

Wentao Hu, Mingkuan Zhao, Shuangyong Song +3

Sparse Mixture-of-Experts (SMoE) architectures have enabled a new frontier in scaling Large Language Models (LLMs), offering superior performance by activating only a fraction of t…
