CODEBLOCK: Learning to Supervise Code at the Right Granularity

Zhijie Deng, Ling Li, Jinlong Pang +5

Supervised fine-tuning of code LLMs typically applies uniform cross-entropy loss to all response tokens, implicitly assuming that every token provides equally useful learning signa…

Reclaiming Low-Quality Instruction Data with Rule-Guided LLM Reconstruction

Zile Yang, Ling Li, Na Di +5

Data selection for supervised fine-tuning (SFT) often discards low-scoring instruction examples that may retain useful supervision. We propose a rule-guided LLM reconstruction fram…

Recognition through Reasoning: Reinforcing Image Geo-localization with Large Vision-Language Models

Ling Li, Yao Zhou, Yuxuan Liang +2

Previous methods for image geo-localization have typically treated the task as either classification or retrieval, often relying on black-box decisions that lack interpretability.…
