Efficient In-Context Medical Segmentation with Meta-Driven Visual Prompt Selection
Medical Image Computing and Computer Assisted Intervention – MICCAI 2024Pages 255–265https://doi.org/10.1007/978-3-031-72114-4_25AbstractIn-context learning (ICL) with Large Vision Models (LVMs) presents a promising avenue in medical image segmentation by reducing the reliance on extensive labeling. However, the ICL performance of LVMs highly depends on the choices of visual ...

AgrAmplifier: Defending Federated Learning Against Poisoning Attacks Through Local Update Amplification
IEEE Transactions on Information Forensics and Security (TIFS), Volume 19Pages 1241–1250https://doi.org/10.1109/TIFS.2023.3333555The collaborative nature of federated learning (FL) poses a major threat in the form of manipulation of local training data and local updates, known as the Byzantine poisoning attack. To address this issue, many Byzantine-robust aggregation rules (<...

WWW '23: Proceedings of the ACM Web Conference 2023Pages 2371–2382https://doi.org/10.1145/3543507.3583542The Poisoning Membership Inference Attack (PMIA) is a newly emerging privacy attack that poses a significant threat to federated learning (FL). An adversary conducts data poisoning (i.e., performing adversarial manipulations on training examples) to ...
Better Together: Attaining the Triad of Byzantine-robust Federated Learning via Local Update Amplification
ACSAC '22: Proceedings of the 38th Annual Computer Security Applications ConferencePages 201–213https://doi.org/10.1145/3564625.3564658Manipulation of local training data and local updates, i.e., the Byzantine poisoning attack, is the main threat arising from the collaborative nature of the federated learning (FL) paradigm. Many Byzantine-robust aggregation algorithms (AGRs) have been ...

A geometry-informed deep learning framework for ultra-sparse 3D tomographic image reconstruction
Computers in Biology and Medicine (CBIM), Volume 148, Issue Chttps://doi.org/10.1016/j.compbiomed.2022.105710AbstractDeep learning affords enormous opportunities to augment the armamentarium of biomedical imaging. However, the pure data-driven nature of deep learning models may limit the model generalizability and application scope. Here we establish ...
Highlights- We propose a geometry-informed deep learning framework for ultra-sparse 3D tomographic image reconstruction (GIIR) by integrating geometric priors of the ...

Scalable Person Re-identification: A Benchmark
ICCV '15: Proceedings of the 2015 IEEE International Conference on Computer Vision (ICCV)Pages 1116–1124This paper contributes a new high quality dataset for person re-identification, named "Market-1501". Generally, current datasets: 1) are limited in scale, 2) consist of hand-drawn bboxes, which are unavailable under realistic settings, 3) have only one ...
