...We have preserved the meaning of the original book Deep Learning as much as possible and retained the original language of the book. However, our level is limited, and we cannot eliminate the variance of many readers. We still need everyone's advice and help to reduce translation bias together. All you have to do is read, then aggregate your suggestions and raise issues (preferably not one by one). If you are sure that your suggestion does not need to be discussed, you can directly initiate a PR. Please download the PDF directly to read. We do not intend to provide formats such as EPUB. Please modify it yourself if necessary.
