Spectral Insights into Data-Oblivious Critical Layers in Large Language Models

ACL 2025finding

Understanding how feature representations evolve across layers in large language models (LLMs) is key to improving their interpretability and robustness. While recent studies have identified critical layers linked to specific functions or behaviors, these efforts typically rely on data-dependent ana…

Exploring Consistency in Graph Representations: from Graph Kernels to Graph Neural Networks

NeurIPS 2024poster

Graph Neural Networks (GNNs) have emerged as a dominant approach in graph representation learning, yet they often struggle to capture consistent similarity relationships among graphs. To capture similarity relationships, while graph kernel methods like the Weisfeiler-Lehman subtree (WL-subtree) and…

TreeMAN: Tree-enhanced Multimodal Attention Network for ICD Coding

COLING 2022main

ICD coding is designed to assign the disease codes to electronic health records (EHRs) upon discharge, which is crucial for billing and clinical statistics. In an attempt to improve the effectiveness and efficiency of manual coding, many methods have been proposed to automatically predict ICD codes…
