Weakly supervised classification of aortic valve malformations using unlabeled cardiac MRI sequences. [PDF]

open access: yesNat Commun, 2019
Biomedical repositories such as the UK Biobank provide increasing access to prospectively collected cardiac imaging, however these data are unlabeled, which creates barriers to their use in supervised machine learning. We develop a weakly supervised deep

Semi-Supervised Hierarchical Graph Classification

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2022
Node classification and graph classification are two graph learning problems that predict the class label of a node and the class label of a graph respectively. A node of a graph usually represents a real-world entity, e.g., a user in a social network, or a document in a document citation network.

Effects of Training Set Size on Supervised Machine-Learning Land-Cover Classification of Large-Area High-Resolution Remotely Sensed Data

open access: yesRemote Sensing, 2021
The size of the training data set is a major determinant of classification accuracy. Nevertheless, the collection of a large training data set for supervised classifiers can be a challenge, especially for studies covering a large area, which may be ...

A Weakly-Supervised Framework for COVID-19 Classification and Lesion Localization From Chest CT

open access: yesIEEE Transactions on Medical Imaging, 2020
Accurate and rapid diagnosis of COVID-19 suspected cases plays a crucial role in timely quarantine and medical treatment. Developing a deep learning-based model for automatic COVID-19 diagnosis on chest CT is helpful to counter the outbreak of SARS-CoV-2.

Self-Supervised Learning for Solar Radio Spectrum Classification

open access: yesUniverse, 2022
Solar radio observation is an important way to study the Sun. Solar radio bursts contain important information about solar activity. Therefore, real-time automatic detection and classification of solar radio bursts are of great value for subsequent solar
