Hello,
I am trying to reproduce the example in chapter 11 of Kotu and Deshpande's book Data Science Concepts and Practice. In particular, I am checking the results in Table 11.6 and they seem all wrong! they are doing centered cosine distances with respect to 2001: a space Odyssey.
My numbers are
and they say it should be
Can anyone please double-check?
Best,
Bernardo

I think all processes are available at http://www.introdatascience.com/.

thank you for your reply! I was not aware of the website of the book, thanks!
The processes will not solve the problem I posed (it is a computation by hand in some sense), but they will be extremely useful to get a better understanding of other chapters.
