Random Forest Prototypes
Hi all,
am I correct that prototypes ( "a way of getting a picture of how the
variables relate to the classification.",
http://www.stat.berkeley.edu/~breiman/RandomForests/cc_home.htm#prototype) are
not yet implemented in Mahout?
I have not found them neither in org.apache.mahout.df.callback nor in mahout
jira tickets.
It it worth creating ticket?
Thanks,
Oleg.

Sounds reasonable so far. Short on details about how to make it happen.

Hi Ted,
thanks.
I will create ticket and will try to contribute patch if my current workload
allows.

Correct on all counts.
Not there and would be very cool to have a ticket (and a patch if you can
start the ball rolling!)
