How is the content of a confusion matrix print?
Hi,
I ‘d like to know how is the content of a confusion matrix print, something like the table in page 226 of version 7 of <Mahout in action>.
Listing 15.2 on page 227 uses the summarize() method of ConfusionMatrix class, but I can’t find the definition of it?
Regards,
Xiaobo Gu

This is merely the toString() method now.
