Embedding a de Rham Complex Structure into Eig-PIELM for Maxwell Eigenvalue Problems

Hao Kang, Liang Li, Xing Li

The perfect electric conductor (PEC) boundary condition alone does not eliminate the gradient nullspace of the Maxwell curl-curl operator. Consequently, a boundary-only Maxwell imp…

Automated Enrichment Analysis with GraphRAG: Efficient Multi-Database ORA Extraction and Biological Interpretation

Guangcan Li, Shuyuan Zheng, Jiayao Liu +2

Over-representation analysis (ORA) is widely used to interpret gene-expression studies, but its outputs are often fragmented across gene-set databases and presented as flat term li…

ToolBottleneckBench: Measuring Tool-Agent Performance under Controlled Pressures and Fixed Harness Budgets

Zichuan Xu, Yuyang Dong, Makoto Onizuka +1

The success score of a tool agent reflects both its model and the budgets of the harness that runs it. We present ToolBottleneckBench, a benchmark that measures tool-agent performa…

Nonlinearity-Aware LoRA: Structured Gate Adaptation under Low-Rank Constraints

Shuai Yuan, Sudong Cai, Bingzhi Chen +4

Low-rank adaptation (LoRA) is commonly viewed as an update-space approximation to full fine-tuning, yet this view is incomplete for self-gated Transformer feed-forward networks. In…

ShapleyLaw: A Game-Theoretic Approach to Multilingual Scaling Laws

Xuyang Cao, Qianying Liu, Chuan Xiao +7

In multilingual pretraining, the test loss of a pretrained model is heavily influenced by the proportion of each language in the pretraining data, namely the \textit{language mixtu…

Data Overvaluation Attack and Truthful Data Valuation in Federated Learning

Shuyuan Zheng, Sudong Cai, Chuan Xiao +4

In collaborative machine learning (CML), data valuation, i.e., evaluating the contribution of each client's data to the machine learning model, has become a critical task for incen…
