如果你喜欢这类讲解，Joel Grus 写的《数据科学从零起步》（Data Science from Scratch）讲解了许多机器学习算法，并且让你在阅读过程中顺手用 Python 手写实现它们的简易版本。书里还讲了线性回归，我在想那本书是不是就是……
If you enjoy these kinds of explanations, "Data Science from Scratch" by Joel Grus explains many machine learning algorithms and has you implement simple versions of them in Python as you read along. It also covers linear regression and I wonder if that book is where the…
……科学？我正在啃这本书，感觉确实挺喜欢的：https://www.amazon.com/Data-Science-Scratch-Principles-Pytho... 我正用 Swift 重写其中的示例来辅助自己学习：https://github.com/melling/data-science-from-scratch-swift 不过来点理论更扎实的书可能会更好。里面的很多问题似乎都需要更多的理论知识。
…science? I working through this book, which I do like: https://www.amazon.com/Data-Science-Scratch-Principles-Pytho... I’m rewriting the examples in Swift to help me learn: https://github.com/melling/data-science-from-scratch-swift Something with a little more theory might be good. Lots of the questions seem to require more theoretical knowledge.
深有同感。我会推荐从 Joel Grus 的《数据科学从零起步》（Data Science From Scratch）之类的书入手，以此来掌握 Python 基础（或者去读 R 语言的对应书籍，我对 R 的书不太熟）。不过我确实越来越发现自己希望能掌握一些专为数据科学定制的 Unix 命令，而且……
I agree. I'd start with something like Joel Grus's Data Science From Scratch to get a handle on the basics in Python (or whatever the R equivalent is, I'm not familiar with R books). I do however find myself more and more wishing I knew data science-specific Unix commands, and…
我很喜欢 Joel Grus 写的《数据科学从零起步》（Data Science from Scratch，2019），现在已经是第二版了，里面用 Python 手动实现各种算法。但我其实更希望作者能直接用 Numpy，或者自己手写数组类，总感觉把“从零起步”搞得有点太……
I like the book "Data Science from Scratch" (2019) by Joel Grus, now in its 2nd edition, which implements algorithms in Python. But I wish the author used Numpy and implemented his own array classes, which I think is taking "from scratch" too…

你可能会喜欢 Joel Grus 写的《数据科学从零起步》（Data Science from Scratch）。他不用任何机器学习库，纯手搓 Python，把底层逻辑讲得一清二楚。
You might like the book 'data science from scratch' by Joel Grus. He uses Python without ML libraries and explains clearly what's going on.
