这里有一个原则同学们要记住：不重要的学术作品大可不读，但重要的要反复重读，读多遍。不要相信重要作品的简化阐释，因为作者究竟怎样想我们不可能从简化的阐释中学到。 - http://blog.sina.com.cn/s/blog_47841af70102ux5w.html

Rarely will I get through every section of every book. The idea is to create a kind of dialogue among the authors, identifying points of overlap and difference. Very often, the ideas from one book will trigger ideas that have you scouring the other books for elaboration. The mixture of ideas from several books will lead to a thought that is not contained in any of the books. When you read in parallel, it's like being in the room while the authors are conversing. The intersecting of ideas almost always stimulates fresh ways of thinking about (and applying) the topic at hand. - http://traderfeed.blogspot.hk[..]ding-in-parallel-becoming-better-at.html

在第一遍阅读时，你并不需要理解一个冗长计算的所有步骤。相反，默认它们是正确的，跳过它们，深入阅读关键的步骤。读公式之间的文字描述，读实验结果，读结论。当你大致明白了文章所谈论的东西之后，你再决定是否把时间花费在代数部分。不要在看不懂的步骤上花太多时间。当你以后有空时，可以重复阅读来慢慢理解它们。 - http://www.infoq.com[..]/2017/08/how-Read-machine-earning-papers https://www.reddit.com[..]achine_learning/?st=j6lm438g&sh=b1d9eba7
