Key challenges across three stages: Data, Modeling, and Application. Data-related issues include transparency, strict cohort selection, preprocessing-related information loss, and lack of interoperability. In modeling, challenges stem from uncertainty in model superiority and poor interpretability. Application limitations include costly deployment, inadequate evaluation metrics, lack of generalizability, and interoperability barriers.
