Quasi-Binarized Autoencoders: An Architecture-Independent Information Bottleneck for Medical Image Anomaly Detection

Shouhei Hanaoka, Takahiro Nakao, Atsushi Takamatsu +2

Unsupervised anomaly detection, which learns only from normal images, is a central task in medical image analysis and remains an open problem. Reconstruction-based methods pass an…

CADD: Context aware disease deviations via restoration of brain images using normative conditional diffusion models

Ana Lawry Aguila, Ayodeji Ijishakin, Juan Eugenio Iglesias +5

Applying machine learning to real-world medical data, e.g. from hospital archives, has the potential to revolutionize disease detection in brain images. However, detecting patholog…

Local Differential Privacy Image Generation Using Flow-based Deep Generative Models

Hisaichi Shibata, Shouhei Hanaoka, Yang Cao +5

Diagnostic radiologists need artificial intelligence (AI) for medical imaging, but access to medical images required for training in AI has become increasingly restrictive. To rele…

Aging prediction using deep generative model toward the development of preventive medicine

Hisaichi Shibata, Shouhei Hanaoka, Yukihiro Nomura +2

From birth to death, we all experience surprisingly ubiquitous changes over time due to aging. If we can predict aging in the digital domain, that is, the digital twin of the human…

X2CT-FLOW: Maximum a posteriori reconstruction using a progressive flow-based deep generative model for ultra sparse-view computed tomography in ultra low-dose protocols

Hisaichi Shibata, Shouhei Hanaoka, Yukihiro Nomura +4

Ultra sparse-view computed tomography (CT) algorithms can reduce radiation exposure of patients, but those algorithms lack an explicit cycle consistency loss minimization and an ex…

KART: Parameterization of Privacy Leakage Scenarios from Pre-trained Language Models

Yuta Nakamura, Shouhei Hanaoka, Yukihiro Nomura +5

For the safe sharing pre-trained language models, no guidelines exist at present owing to the difficulty in estimating the upper bound of the risk of privacy leakage. One problem i…

On the Matrix-Free Generation of Adversarial Perturbations for Black-Box Attacks

Hisaichi Shibata, Shouhei Hanaoka, Yukihiro Nomura +2

In general, adversarial perturbations superimposed on inputs are realistic threats for a deep neural network (DNN). In this paper, we propose a practical generation method of such…
