Which Data Attributes Stimulate Math and Code Reasoning? An Investigation via Influence Functions

NeurIPS 2025poster

Large language models (LLMs) have demonstrated remarkable reasoning capabilities in math and coding, often bolstered by post-training on the chain-of-thoughts (CoTs) generated by stronger models. However, existing strategies for curating such training data predominantly rely on heuristics, limiting…

MetaFill: Text Infilling for Meta-Path Generation on Heterogeneous Information Networks

EMNLP 2022main

Heterogeneous information network (HIN) is essential to study complicated networks containing multiple edge types and node types. Meta-path, a sequence of node types and edge types, is the core technique to embed HINs. Since manually curating meta-paths is time-consuming, there is a pressing need to…
