2. "mathematical beauty" book review:

 　　Mathematical beauty at first glance thought it was dedicated to mathematics book, found it to be looked after and Information Science, a closely related works. After the turn of the articles inside, I was shocked to the wonderful world of information described in the book, let me a deep understanding of the importance of mathematics. That article first 1.9 "How to determine the relevance of web pages and queries", the query phrase, we must take the keyword phrase in the ability to predict the subject of consideration. Examples cited in the book is "the application of atomic energy," according to the normal way of thinking to think, it is clear on the importance of "atomic energy"> "Applications" >> "" but how to get the computer to distinguish between the importance of it? That is the need to use mathematics, using mathematical methods to investigate the frequency of keywords to determine the weight of keywords. TF / IDF concept mentioned in the book is used in many fields, and even now the search engines are widely used. Turning back to just words, the computer needs these six words separated into three keywords, which in turn statistical language models related to Chinese word, which is the content of the book's first 1.2. Visible mathematics is used in all aspects of the computer field, mathematical problem solving in natural language aspect is even more significant effect, is significant. Since the mathematical advantage to spend on the computer, it naturally can not do without the algorithm, the algorithm can be described as the soul of software development, a good algorithm to save space and time, decide the merits of the software. Since there is no complete reading this book, plus limit the level of knowledge, I can only point out these thoughts, but I'm sure this is a book of information in the field of a very good, worth repeating to read, understand mathematics and computer Charm.
