ChLogic: Evaluating Robustness of Logical Reasoning in Chinese Expressions

Peixian Zhou, Yuxu Chen, Chaorui Zhang +3

Large language models perform increasingly well on standardized logical reasoning benchmarks, but whether this ability remains robust beyond English is unclear. We introduce ChLogi…

On the Non-decoupling of Supervised Fine-tuning and Reinforcement Learning in Post-training

Xueyan Niu, Bo Bai, Wei Han +1

Post-training of large language models routinely interleaves supervised fine-tuning (SFT) with reinforcement learning (RL). These two methods have different objectives: SFT minimiz…

Memo-SQL: Structured Decomposition and Experience-Driven Self-Correction for Training-Free NL2SQL

Zerui Yang, Weichuan Wang, Yanwei Xu +4

Existing NL2SQL systems face two critical limitations: (1) they rely on in-context learning with only correct examples, overlooking the rich signal in historical error-fix pairs th…

ER-RAG: Enhance RAG with ER-Based Unified Modeling of Heterogeneous Data Sources

Yikuan Xia, Jiazun Chen, Yirui Zhan +6

Large language models (LLMs) excel in question-answering (QA) tasks, and retrieval-augmented generation (RAG) enhances their precision by incorporating external evidence from diver…
