Recognize Your Orchestrator: An Entropy Dynamics Perspective for LLM Multi-Agent Systems

ICML 2026poster

The transition from single-turn models to Multi-Agent Systems (MAS) promises enhanced problem-solving capabilities, yet the centralized orchestration topology remains a critical point of fragility. To analyze this, we propose a Mean-Field Entropy Dynamics framework, modeling the orchestration proces…

Breast Ultrasound Computer-Aided Diagnosis Using Structure-Aware Triplet Path Networks

ICASSP 2024accepted

Breast ultrasound (BUS) is an effective imaging modality for breast cancer diagnosis. The structural characteristics of breast lesions play an important role in computer-aided diagnosis. In this paper, a novel structure-aware triplet path network (SATPN) was designed to integrate classification and…

EFUF: Efficient Fine-Grained Unlearning Framework for Mitigating Hallucinations in Multimodal Large Language Models

EMNLP 2024main

Multimodal large language models (MLLMs) have attracted increasing attention in the past few years, but they may still generate descriptions that include objects not present in the corresponding images, a phenomenon known as object hallucination. To eliminate hallucinations, existing methods manuall…
