Similar to the development of children from appearance and color to older children, they can be classified according to concepts. For example, if they know the concept of "food", no matter what kind of vegetables they look like, they should be classified into one category. The classification of biology has also developed in this way. The earliest method is to identify and distinguish species according to phenotypic characteristics, and to classify them step by step according to the degree of phenotypic similarity, so as to establish a classification system that is easy to retrieve. This is the principle of phenotypic classification. However, the problem of phenotypic classification is that it is difficult to reveal the essential laws of things. Many creatures with very different shapes may have kinship relationships. For example, the online sentence "When I knew sunflowers belonged to Compositae, I collapsed" is what it means.

1. As a math student, I have studied math for four years, and I don't agree with the bibliography you gave at random. First, there is no step type and it is unfriendly to beginners. Your title and the purpose of writing this series are probably for Xiaobai to see. So, may I ask, a Xiaobai needs to see the principle of mathematical analysis? ? Is it necessary to look at Princeton Calculus Principle to learn artificial intelligence? ? In my shallow understanding, the biggest difference between mathematical analysis and advanced mathematics is the same theorem. High numbers only require that they can be used. Mathematical analysis is rigorous and will definitely give proof. However, for the mathematics needed in most artificial intelligence, you need to prove the correctness and completeness of this theorem in your work? ? I'm afraid the project will be closed long ago when you prove it. You replied to me that this is only a bibliography, not a recommended bibliography, but most of the following comments decided to give up when they saw the book list. If you put these books out, it will be instructive to those who read your articles. I think you are misleading people. Second, I have roughly deduced from the number of references you have made that you may not have a framework for the mathematics of the whole artificial intelligence, otherwise there would not have been such irresponsible recommendations. However, out of respect for you, I did not question your ability. I only gave a brief recommendation in the comments on the suitable math bibliography for beginners.
