Infant hip screening using multi-class ultrasound scan segmentation

no code implementations8 Nov 2022 Andrew Stamper, Abhinav Singh, James McCouat, Irina Voiculescu

Developmental dysplasia of the hip (DDH) is a condition in infants where the femoral head is incorrectly located in the hip joint.

Triple-View Feature Learning for Medical Image Segmentation

2 code implementations12 Aug 2022 Ziyang Wang, Irina Voiculescu

The confidence of each model gets improved through the other two views of the feature learning.

Learning Underrepresented Classes from Decentralized Partially Labeled Medical Images

no code implementations30 Jun 2022 Nanqing Dong, Michael Kampffmeyer, Irina Voiculescu

In the second stage, the decentralized partially labeled data are exploited to learn an energy-based multi-label classifier for the common classes.

Revisiting Vicinal Risk Minimization for Partially Supervised Multi-Label Classification Under Data Scarcity

no code implementations19 Apr 2022 Nanqing Dong, Jiayi Wang, Irina Voiculescu

Due to the high human cost of annotation, it is non-trivial to curate a large-scale medical dataset that is fully labeled for all classes of interest.

Contour-Hugging Heatmaps for Landmark Detection

1 code implementation CVPR 2022 James McCouat, Irina Voiculescu

We find that this method not only achieves localisation results on par with other state-of-the-art methods but also an uncertainty score which correlates with the true error for each landmark thereby bringing an overall step change in what a generic computer vision method for landmark detection should be capable of.

Federated Contrastive Learning for Decentralized Unlabeled Medical Images

no code implementations15 Sep 2021 Nanqing Dong, Irina Voiculescu

A label-efficient paradigm in computer vision is based on self-supervised contrastive pre-training on unlabeled data followed by fine-tuning with a small number of labels.

Negational Symmetry of Quantum Neural Networks for Binary Pattern Classification

1 code implementation20 May 2021 Nanqing Dong, Michael Kampffmeyer, Irina Voiculescu, Eric Xing

In this work, we provide some theoretical insight into the properties of QNNs by presenting and analyzing a new form of invariance embedded in QNNs for both quantum binary classification and quantum representation learning, which we term negational symmetry.

Quadruple Augmented Pyramid Network for Multi-class COVID-19 Segmentation via CT

no code implementations9 Mar 2021 Ziyang Wang, Irina Voiculescu

COVID-19, a new strain of coronavirus disease, has been one of the most serious and infectious disease in the world.

Towards Robust Partially Supervised Multi-Structure Medical Image Segmentation on Small-Scale Data

no code implementations28 Nov 2020 Nanqing Dong, Michael Kampffmeyer, Xiaodan Liang, Min Xu, Irina Voiculescu, Eric P. Xing

To bridge the methodological gaps in partially supervised learning (PSL) under data scarcity, we propose Vicinal Labels Under Uncertainty (VLUU), a simple yet efficient framework utilizing the human structure similarity for partially supervised medical image segmentation.
