Rewiring Experts on the Fly:Continuous Rerouting for Better Online Adaptation in Mixture-of-Expert models

Guinan Su, Yanwu Yang, Li Shen +3

Mixture-of-Experts (MoE) models achieve efficient scaling through sparse expert activation, but often suffer from suboptimal routing decisions due to distribution shifts in deploym…

When Fewer Layers Break More Chains: Layer Pruning Harms Test-Time Scaling in LLMs

Keyu Wang, Tian Lyu, Guinan Su +4

Layer pruning has emerged as a widely adopted technique for improving the efficiency of large language models (LLMs). Although existing methods demonstrate strong performance reten…

Demystifying the Roles of LLM Layers in Retrieval, Knowledge, and Reasoning

Xinyuan Song, Keyu Wang, PengXiang Li +2

Recent studies suggest that the deeper layers of Large Language Models (LLMs) contribute little to representation learning and can often be removed without significant performance…

Model Unmerging: Making Your Models Unmergeable for Secure Model Sharing

Zihao Wang, Enneng Yang, Lu Yin +2

Model merging leverages multiple finetuned expert models to construct a multi-task model with low cost, and is gaining increasing attention. However, as a growing number of finetun…

Double-Checker: Enhancing Reasoning of Slow-Thinking LLMs via Self-Critical Fine-Tuning

Xin Xu, Tianhao Chen, Fan Zhang +11

While slow-thinking large language models (LLMs) exhibit reflection-like reasoning, commonly referred to as the "aha moment:, their ability to generate informative critiques and re…

AlphaDecay: Module-wise Weight Decay for Heavy-Tailed Balancing in LLMs

Di He, Songjun Tu, Ajay Jaiswal +4

Weight decay is a standard regularization technique for training large language models (LLMs). While it is common to assign a uniform decay rate to every layer, this approach overl…

The Curse of Depth in Large Language Models

Wenfang Sun, Xinyuan Song, Pengxiang Li +3

In this paper, we introduce the Curse of Depth, a concept that highlights, explains, and addresses the recent observation in modern Large Language Models (LLMs) where nearly half o…
