dis criminative tasks

Advancements in Medical Vision-Language Pre-training (Medical-VLP) progress rapidly by learning representations from paired radiology reports. Nevertheless, there still remain two issues that restrict the development of Medical-VLP: the scarcity of parallel image-report pair and monotony of pre-training tasks. Thus, we propose Multi-Grained Cross-Domain Report Searching (CDRS) strategy, and Multi-Task Driven Language-Image Pre-Training (MLIP) framework.
