Towards Comprehensive Post Safety Alignment of Large Language Models via Safety Patching

IJCAI 2026

Safety alignment of large language models (LLMs) has been gaining increasing attention. However, current safety-aligned LLMs suffer from the fragile and imbalanced safety mechanisms, which can still be induced to generate unsafe responses, exhibit over-safety by rejecting safe user inputs, and fail

AdaSteer: Your Aligned LLM is Inherently an Adaptive Jailbreak Defender

EMNLP 2025

Despite extensive efforts in safety alignment, large language models (LLMs) remain vulnerable to jailbreak attacks. Activation steering offers a training-free defense method but relies on fixed steering coefficients, resulting in suboptimal protection and increased false rejections of benign inputs.

Beware of Your Po! Measuring and Mitigating AI Safety Risks in Role-Play Fine-Tuning of LLMs

ACL 2025long

Role-playing enables large language models (LLMs) to engage users in immersive and personalized interactions, but it also introduces significant safety risks. Existing role-play fine-tuning techniques improve role adaptability but may degrade safety performance, particularly for villainous character…

Chain of Strategy Optimization Makes Large Language Models Better Emotional Supporter

EMNLP 2025

The growing emotional stress in modern society has increased the demand for Emotional Support Conversations (ESC). While Large Language Models (LLMs) show promise for ESC, they face two key challenges: (1) low strategy selection accuracy, and (2) preference bias, limiting their adaptability to users

Teaching Language Models to Evolve with Users: Dynamic Profile Modeling for Personalized Alignment

NeurIPS 2025poster

Personalized alignment is essential for enabling large language models (LLMs) to engage effectively in user-centric dialogue. While recent prompt-based and offline optimization methods offer preliminary solutions, they fall short in cold-start scenarios and long-term personalization due to their inh…

When Less Language is More: Language-Reasoning Disentanglement Makes LLMs Better Multilingual Reasoners

NeurIPS 2025spotlight

Multilingual reasoning remains a significant challenge for large language models (LLMs), with performance disproportionately favoring high-resource languages. Drawing inspiration from cognitive neuroscience, which suggests that human reasoning functions largely independently of language processing,…

Both Matter: Enhancing the Emotional Intelligence of Large Language Models without Compromising the General Intelligence

ACL 2024findings

Emotional Intelligence (EI), consisting of emotion perception, emotion cognition and emotion expression, plays the critical roles in improving user interaction experience for the current large language model (LLM) based conversational general AI assistants. Previous works mainly focus on raising the…

SAPT: A Shared Attention Framework for Parameter-Efficient Continual Learning of Large Language Models

ACL 2024long

The continual learning (CL) ability is vital for deploying large language models (LLMs) in the dynamic world. Existing methods devise the learning module to acquire task-specific knowledge with parameter-efficient tuning (PET) block and the selection module to pick out the corresponding one for the…
