LIFT: A Novel Framework for Enhancing Long-Context Understanding of LLMs via Long Input Fine-Tuning

Yansheng Mao, Yufei Xu, Jiaqi Li +5

Long-context understanding remains challenging for LLMs due to limited context windows. This paper introduces Long Input Fine-Tuning (LIFT), a framework that improves the long-cont…

GREPO: A Benchmark for Graph Neural Networks on Repository-Level Bug Localization

Juntong Wang, Libin Chen, Xiyuan Wang +4

Repository-level bug localization-the task of identifying where code must be modified to fix a bug-is a critical software engineering challenge. Standard Large Language Modles (LLM…

LiteToken: Removing Intermediate Merge Residues From BPE Tokenizers

Yike Sun, Haotong Yang, Zhouchen Lin +1

Tokenization is fundamental to how language models represent and process text, yet the behavior of widely used BPE tokenizers has received far less study than model architectures a…
