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 
0.25
1.00
-0.52
-0.73
-0.01

and they say it should be 



Can anyone please double-check?

Best,
Bernardo

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

    Hello Sven,

    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. 

    Best,
    Bernardo
