MAC-Tuning: LLM Multi-Compositional Problem Reasoning with Enhanced Knowledge Boundary Awareness

no code implementations30 Apr 2025 Junsheng Huang, Zhitao He, Sandeep Polisetty, Qingyun Wang, May Fung

With the widespread application of large language models (LLMs), the issue of generating non-existing facts, known as hallucination, has garnered increasing attention.

Enhancing Language Multi-Agent Learning with Multi-Agent Credit Re-Assignment for Interactive Environment Generalization

no code implementations20 Feb 2025 Zhitao He, Zijun Liu, Peng Li, May Fung, Ming Yan, Ji Zhang, Fei Huang, Yang Liu

To address these issues, we propose CollabUIAgents, a multi-agent reinforcement learning framework with a novel multi-agent credit re-assignment (CR) strategy, assigning process rewards with LLMs rather than environment-specific rewards and learning with synthesized preference data, in order to foster generalizable, collaborative behaviors among the role-free agents' policies.

Group-Adaptive Threshold Optimization for Robust AI-Generated Text Detection

1 code implementation6 Feb 2025 Minseok Jung, Cynthia Fuertes Panizo, Liam Dugan, May Fung, Pin-Yu Chen, Paul Pu Liang

The advancement of large language models (LLMs) has made it difficult to differentiate human-written text from AI-generated text.

CALM: Unleashing the Cross-Lingual Self-Aligning Ability of Language Model Question Answering

no code implementations30 Jan 2025 Yumeng Wang, Zhiyuan Fan, Qingyun Wang, May Fung, Heng Ji

To address this, we explore the Cross-Lingual Self-Aligning ability of Language Models (CALM) to align knowledge across languages.

MentalArena: Self-play Training of Language Models for Diagnosis and Treatment of Mental Health Disorders

1 code implementation9 Oct 2024 Cheng Li, May Fung, Qingyun Wang, Chi Han, Manling Li, Jindong Wang, Heng Ji

In this paper, we introduce MentalArena, a self-play framework to train language models by generating domain-specific personalized data, where we obtain a better model capable of making a personalized diagnosis and treatment (as a therapist) and providing information (as a patient).

Aligning LLMs with Individual Preferences via Interaction

1 code implementation4 Oct 2024 Shujin Wu, May Fung, Cheng Qian, Jeonghwan Kim, Dilek Hakkani-Tur, Heng Ji

To address this gap, we train LLMs that can ''interact to align'', essentially cultivating the meta-skill of LLMs to implicitly infer the unspoken personalized preferences of the current user through multi-turn conversations, and then dynamically align their following behaviors and responses to these inferred preferences.
