Learn from Your Mistakes: Tree-like Self-Play on Vulnerability Nodes for Secure Code LLMs

ICML 2026poster

While Large Language Models (LLMs) excel in code generation, they remain prone to replicating subtle yet critical vulnerabilities endemic to their training data. Current alignment techniques, such as Supervised Fine-Tuning (SFT) and Reinforcement Learning (RL), typically apply coarse-grained optimiz…

Data Augmentation for Cross-domain Parsing via Lightweight LLM Generation and Tree Hybridization

COLING 2025main

Cross-domain constituency parsing remains a challenging task due to the lack of high-quality out-of-domain data. In this paper, we propose a data augmentation method via lightweight large language model (LLM) generation and tree hybridization. We utilize LLM to generate phrase structures (subtrees)…
