The requirement of artificial intelligence (AI) application and the enhancement for inflammatory bowel disease (IBD) studies. The high-quality data at a certain volume are the basis of building and training the machine learning (ML) models. Making the appropriate match between the dataset and analysis methods is also an essential step, which can influence both accuracy and interpretability of results. The AI application in IBD study was summarized and sorted by the research purpose. In the field of IBD etiology, diagnosis, and treatment, AI methods played distinct roles.
