MedCLIP: Contrastive Learning from Unpaired Medical Images and Text

1 code implementation18 Oct 2022 Zifeng Wang, Zhenbang Wu, Dinesh Agarwal, Jimeng Sun

Existing vision-text contrastive learning like CLIP aims to match the paired image and caption embeddings while pushing others apart, which improves representation transferability and supports zero-shot prediction.

Knowledge-Driven New Drug Recommendation

no code implementations11 Oct 2022 Zhenbang Wu, Huaxiu Yao, Zhe Su, David M Liebovitz, Lucas M Glass, James Zou, Chelsea Finn, Jimeng Sun

However, newly approved drugs do not have much historical prescription data and cannot leverage existing drug recommendation methods.

AutoMap: Automatic Medical Code Mapping for Clinical Prediction Model Deployment

no code implementations4 Mar 2022 Zhenbang Wu, Cao Xiao, Lucas M Glass, David M Liebovitz, Jimeng Sun

To tackle this problem, we propose AutoMap to automatically map the medical codes across different EHR systems in a coarse-to-fine manner: (1) Ontology-level Alignment: We leverage the ontology structure to learn a coarse alignment between the source and target medical coding systems; (2) Code-level Refinement: We refine the alignment at a fine-grained code level for the downstream tasks using a teacher-student framework.
