From Characters to Words: Hierarchical Pre-trained Language Model for Open-vocabulary Language Understanding

Li Sun, Florian Luisier, Kayhan Batmanghelich +2

Current state-of-the-art models for natural language understanding require a preprocessing step to convert raw text into discrete tokens. This process known as tokenization relies…

DrasCLR: A Self-supervised Framework of Learning Disease-related and Anatomy-specific Representation for 3D Medical Images

Ke Yu, Li Sun, Junxiang Chen +3

Large-scale volumetric medical images with annotation are rare, costly, and time prohibitive to acquire. Self-supervised learning (SSL) offers a promising pre-training and feature…

Context-aware Self-supervised Learning for Medical Images Using Graph Neural Network

Li Sun, Ke Yu, Kayhan Batmanghelich

Although self-supervised learning enables us to bootstrap the training by exploiting unlabeled data, the generic self-supervised methods for natural images do not sufficiently inco…

Can contrastive learning avoid shortcut solutions?

Joshua Robinson, Li Sun, Ke Yu +3

The generalization of representations learned via contrastive learning depends crucially on what features of the data are extracted. However, we observe that the contrastive loss d…

Context Matters: Graph-based Self-supervised Representation Learning for Medical Images

Li Sun, Ke Yu, Kayhan Batmanghelich

Supervised learning method requires a large volume of annotated datasets. Collecting such datasets is time-consuming and expensive. Until now, very few annotated COVID-19 imaging d…
