A workflow for data integration for AI/ML modeling in precision medicine. ① A wide variety of data sources with diverse features exists. Hence, different approaches to data collection and pre-processing are needed ②. ③ Integrating such diverse and heterogeneous data is one of the grand challenges to the successful application of AI/ML approaches to Precision Medicine. Overcoming such challenges will bring important improvements to Precision Medicine ④.
