Joint-GCG: Unified Gradient-Based Poisoning Attacks on Retrieval-Augmented Generation Systems

AAAI 2026technical

Retrieval-Augmented Generation (RAG) systems enhance Large Language Models (LLMs) by retrieving relevant documents from external corpora before generating responses. This approach significantly expands LLM capabilities by leveraging vast, up-to-date external knowledge. However, this reliance on exte

From Allies to Adversaries: Manipulating LLM Tool-Calling through Adversarial Injection

NAACL 2025long

Tool-calling has changed Large Language Model (LLM) applications by integrating external tools, significantly enhancing their functionality across diverse tasks. However, this integration also introduces new security vulnerabilities, particularly in the tool scheduling mechanisms of LLM, which have…

Let Modalities Teach Each Other: Modal-Collaborative Knowledge Extraction and Fusion for Multimodal Knowledge Graph Completion

NAACL 2025findings

Multimodal knowledge graph completion (MKGC) aims to predict missing triples in MKGs using multimodal information. Recent research typically either extracts information from each modality separately to predict, then ensembles the predictions at the decision stage, or projects multiple modalities int…

Symmetric Bi-branch Modality-search Aggregation Network for Multi-modal Liver Segmentation

ICASSP 2025accepted

Medical image segmentation is crucial for diagnosis and surgical planning of liver diseases. The existing methods mainly focus on global or local features and neglect spatial dependencies among modalities and blurred boundaries. To tackle these challenges, we propose a symmetric bi-branch modality-s…

Integrating Representation Subspace Mapping with Unimodal Auxiliary Loss for Attention-based Multimodal Emotion Recognition

COLING 2024main

Multimodal emotion recognition (MER) aims to identify emotions by utilizing affective information from multiple modalities. Due to the inherent disparities among these heterogeneous modalities, there is a large modality gap in their representations, leading to the challenge of fusing multiple modali…
