Artificial intelligence is a branch of computer science capable of analyzing complex medical data to promote diagnosis processes, treatment protocol development, drug development, personalized medicine, and patient monitoring. It usually integrates big data, machine learning, algorithm modeling, and data bioinformatics. AI can be divided into two parts: 1) machine learning, structured data (i.e. images and genetic data) are analyzed; 2) natural language processing, unstructured data are analyzed. With the development of analysis methods, algorithms, and applications, AI has revolutionized medical diagnostics in cancer, nervous system disease, cardiovascular disease, liver disease, congenital cataract disease, etc.
