Choose artificial intelligence. ArtificialIntelligence, abbreviated as AI in English, is a new technology science that studies and develops theories, methods, technologies and application systems that simulate, extend and expand human intelligence. It tries to understand the nature of intelligence and produces a new intelligent machine that can respond in a way similar to human intelligence. The research in this field includes robot, language recognition, image recognition, natural language processing and expert system. Mathematical modeling is a practice of using mathematical methods to solve practical problems. That is, through the process of abstraction, simplification, hypothesis and introduction of variables, the actual problem is mathematically expressed, the mathematical model is established, and then advanced mathematical methods and computer technology are used to solve it. Mathematical modeling can be commonly understood as mathematics+modeling, that is, using mathematical knowledge such as statistics, linear algebra and integral calculus to build mathematical models and solve problems through models.
