Hi @rasbt,

I found that solution to the Excercise 2.1 already exists also in the notebook with the main code (section "Experiments with unknown words")

Thank you.

Ah yes, thanks. I think I used the code for generating the figure in the chapter and then forgot to remove it from the notebook. I just cleaned it up!
