MedCLIP: Contrastive Learning from Unpaired Medical Images and Text
Zifeng Wang, Zhenbang Wu, Dinesh Agarwal +1
Existing vision-text contrastive learning like CLIP aims to match the paired image and caption embeddings while pushing others apart, which improves representation transferability…
PromptEHR: Conditional Electronic Healthcare Records Generation with Prompt Learning
Zifeng Wang, Jimeng Sun
Accessing longitudinal multimodal Electronic Healthcare Records (EHRs) is challenging due to privacy concerns, which hinders the use of ML for healthcare applications. Synthetic EH…
Artificial Intelligence for In Silico Clinical Trials: A Review
Zifeng Wang, Chufan Gao, Lucas M. Glass +1
A clinical trial is an essential step in drug development, which is often costly and time-consuming. In silico trials are clinical trials conducted digitally through simulation and…
Lifelong Learning based Disease Diagnosis on Clinical Notes
Zifeng Wang, Yifan Yang, Rui Wen +3
Current deep learning based disease diagnosis systems usually fall short in catastrophic forgetting, i.e., directly fine-tuning the disease diagnosis model on new tasks usually lea…
Information Theoretic Counterfactual Learning from Missing-Not-At-Random Feedback
Zifeng Wang, Xi Chen, Rui Wen +3
Counterfactual learning for dealing with missing-not-at-random data (MNAR) is an intriguing topic in the recommendation literature since MNAR data are ubiquitous in modern recommen…
Online Disease Self-diagnosis with Inductive Heterogeneous Graph Convolutional Networks
Zifeng Wang, Rui Wen, Xi Chen +4
We propose a Healthcare Graph Convolutional Network (HealGCN) to offer disease self-diagnosis service for online users based on Electronic Healthcare Records (EHRs). Two main chall…
