Extra-Merge: Tracing the Rank-1 Subspace of Model Merging in Language Model Pre-Training
Wenjie Zhou, Bohan Wang, Hongtao Zhang +3
Model merging has emerged as a lightweight paradigm for enhancing Large Language Models (LLMs), yet its underlying mechanisms remain poorly understood. In this work, we analyze lat…

Generalization Bounds of Stochastic Gradient Descent in Homogeneous Neural Networks
Wenquan Ma, Yang Sui, Jiaye Teng +3
Algorithmic stability is among the most potent techniques in generalization analysis. However, its derivation usually requires a stepsize under non-convex…

Exposing Vulnerabilities in Explanation for Time Series Classifiers via Dual-Target Attacks
Bohan Wang, Zewen Liu, Lu Lin +4
Interpretable time series deep learning systems are often assessed by checking temporal consistency on explanations, implicitly treating this as evidence of robustness. We show tha…
