I am implementing recommendation techniques in Mahout. However, I have a
requirement for a custom evaluation metrics other than predefined or
built-in ones. So,
Q: Can someone please point me to sample custom Evaluator or metric
implementation in Mahout?
Thanks

Hello All,
Can someone please guide me to an example of Spectral Clustering in Mahout
which uses NamedVectors?
Thanks
Vikas
Hello,
I am using Mahout Spectral clustering example which internally calls a map
reduce job. Right now, it is using */tmp/hadoop-/mapred/..*
directory by default for its operations.
Can someone please let me know how to make mahout to use a different path?
Thanks

It seems like I just require to set the right resource (Path or string) in
the Configuration object passed as the parameter of the Spectral
Clustering. But not able to figure out which one.
Thanks
