t3 and t4 : CanopyDriver

[Paritosh Ranjan <pr...@xebia.com>]

Hi,

I am not able to find any info on what t3 and t4 parameters are in 
CanopyDriver's run method. Can someone explain these two parameters ( t3 
and t4 )  or point me to a link where it is explained?

PS : In CanopyClustering's explanation I only see t1 and t2 which I 
understand.

Thanks and Regards,
Paritosh Ranjan

I found this link about t3 and t4 parameters.

http://mail-archives.apache.org/mod_mbox/mahout-user/201106.mbox/%3C99CF5A2B2A1D9542A589C5F5EBD3DA03040B124B14@rock.narus.com%3E

This discussion, says that, t3 and t4 values needs to be guessed. And, 
the vectors will not be that sparse in reduce phase.
I have tried t1/1000000000 and t2/1000000000 values for t3 and t4. Still 
it does not work.

I am stuck due to this, because I am getting different results on 
sequential and mapreduce for Canopy Clustering, and, I am not able to 
guess t3 and t4's value which is supposed to solve this problem ( 
according to the discussion in the link pasted above ).

Can someone help me?
