Adaptive Social Learning via Mode Policy Optimization for Language Agents

ICLR 2026poster

Effective social intelligence simulation requires language agents to dynamically adjust reasoning depth, a capability notably absent in current studies. Existing methods either lack explicit reasoning or employ lengthy Chain-of-Thought reasoning uniformly across all scenarios, resulting in excessive…

DEMO: Reframing Dialogue Interaction with Fine-grained Element Modeling

ACL 2025finding

Large language models (LLMs) enabled dialogue systems have become one of the central modes in human-machine interaction, which bring about vast amounts of conversation logs and increasing demand for dialogue generation. The dialogue’s life-cycle spans from Prelude through Interlocution to Epilogue,…

IOPO: Empowering LLMs with Complex Instruction Following via Input-Output Preference Optimization

ACL 2025long

In the realm of large language models (LLMs), the ability of models to accurately follow instructions is paramount as more agents and applications leverage LLMs for construction, where the complexity of instructions are rapidly increasing. However, on the one hand, there is only a certain amount of…

On the Role of Attention Heads in Large Language Model Safety

ICLR 2025oral

Large language models (LLMs) achieve state-of-the-art performance on multiple language tasks, yet their safety guardrails can be circumvented, leading to harmful generations. In light of this, recent research on safety mechanisms has emerged, revealing that when safety representations or component a…

Revealing and Mitigating the Challenge of Detecting Character Knowledge Errors in LLM Role-Playing

EMNLP 2025

Large language model (LLM) role-playing has gained widespread attention. Authentic character knowledge is crucial for constructing realistic LLM role-playing agents. However, existing works usually overlook the exploration of LLMs’ ability to detect characters’ known knowledge errors (KKE) and unkno

Adaptive Data Augmentation for Aspect Sentiment Quad Prediction

ICASSP 2024accepted

Aspect sentiment quad prediction (ASQP) aims to predict the quad sentiment elements for a given sentence, which is a critical task in the field of aspect-based sentiment analysis. However, the data imbalance issue has not received sufficient attention in ASQP task. In this paper, we divide the issue…

How Alignment and Jailbreak Work: Explain LLM Safety through Intermediate Hidden States

EMNLP 2024finding

Large language models (LLMs) rely on safety alignment to avoid responding to malicious user inputs. Unfortunately, jailbreak can circumvent safety guardrails, resulting in LLMs generating harmful content and raising concerns about LLM safety. Due to language models with intensive parameters often re…

Improving Chinese Spelling Correction with Text-Phonetics Differentiation and Adaptive Fusion

ICASSP 2024accepted

Chinese Spelling Correction (CSC) aims to detect and correct the misspelled characters in Chinese texts. Recent studies have achieved great success by incorporating the phonetic information for task predictions. Still, existing methods suffer from two limitations: 1) The differentiated information b…

Win-Win: A Privacy-Preserving Federated Framework for Dual-Target Cross-Domain Recommendation

AAAI 2023technical

Cross-domain recommendation (CDR) aims to alleviate the data sparsity by transferring knowledge from an informative source domain to the target domain, which inevitably proposes stern challenges to data privacy and transferability during the transfer process. A small amount of recent CDR works have…

Exploring Periodicity and Interactivity in Multi-Interest Framework for Sequential Recommendation

IJCAI 2021poster

Sequential recommendation systems alleviate the problem of information overload, and have attracted increasing attention in the literature. Most prior works usually obtain an overall representation based on the user’s behavior sequence, which can not sufficiently reflect the multiple interests of th…

Improving Distantly-Supervised Named Entity Recognition with Self-Collaborative Denoising Learning

EMNLP 2021main

Distantly supervised named entity recognition (DS-NER) efficiently reduces labor costs but meanwhile intrinsically suffers from the label noise due to the strong assumption of distant supervision. Typically, the wrongly labeled instances comprise numbers of incomplete and inaccurate annotations, whi…
