Optimization and Robustness-Informed Membership Inference Attacks for LLMs

AAAI 2026technical

The proliferation of Large Language Models (LLMs) has raised concerns over training data privacy. Membership Inference Attacks (MIA), aiming to identify whether specific data was used for training, pose significant privacy risks. However, existing MIA methods struggle to address the scale and comple

EM-MIAs: Enhancing Membership Inference Attacks in Large Language Models through Ensemble Modeling

ICASSP 2025accepted

With the widespread application of large language models (LLM), concerns about the privacy leakage of model training data have increasingly become a focus. Membership Inference Attacks (MIAs) have emerged as a critical tool for evaluating the privacy risks associated with these models. Although exis…

Prompt-Driven Referring Image Segmentation with Instance Contrasting

CVPR 2024poster

Referring image segmentation (RIS) aims to segment the target referent described by natural language. Recently large-scale pre-trained models e.g. CLIP and SAM have been successfully applied in many downstream tasks but they are not well adapted to RIS task due to inter-task differences. In this pap…

CrossDet: Crossline Representation for Object Detection

ICCV 2021poster

Object detection aims to accurately locate and classify objects in an image, which requires precise object representations. Existing methods usually use rectangular anchor boxes or a set of points to represent objects. However, these methods either introduce background noise or miss the continuous a…

Scene Parsing via Integrated Classification Model and Variance-Based Regularization

CVPR 2019poster

Scene Parsing is a challenging task in computer vision, which can be formulated as a pixel-wise classification problem. Existing deep-learning-based methods usually use one general classifier to recognize all object categories. However, the general classifier easily makes some mistakes in dealing wi…
