[PLearn-developers] Modification to LinearRegressor.cc

[Christian D. <do...@ap...>]

Hello PLearners,

 We are currently working on the replication under PLearn of some 
results obtained otherwise using a very complicated model: An Evil 
Linear Regression! Obvisously, in this tremendous task, we could not 
succeed at first trial...  After a few hours of gdb,
I finally understood that, while weight decay means weight decay for the 
rest of the universe,  in a LinearRegressor it meant
 
    weight_decay*train_set.length()

After some voodoo incantations and a little conversation with some well 
known PLearners, we decided that, from now on, weight decay will mean 
weight decay even in the fascinating world of PLearn. Hence, 
LinearRegressor.cc was modified and committed.

If it may, anyhow, cause any problem to anyone, please let me know.
'Till then, tata.

PS: For those who'd like to know, I finally succeeded, thanks to that 
modification, in the colossal challenge of linear regression!
