Explanation of mathematical principles in word2vec (1) contents and Preface

      
Word2vec is a toolkit launched by Google in 2013 by open source for obtaining word vector. It is simple and efficient, so it has aroused the attention of many people. Tomas Mikolov, the author of word2vec, did not talk about too many algorithm details in two related papers [3, 4], thus increasing the mystery of this toolkit to a certain extent. Some people who couldn't help but choose to take a look at the source code through anatomy. Out of curiosity, I became one of them. After reading the code, I felt that I had gained a lot. I wrote it into my documents and gave it to anyone who needed it.
