Just kidding: Thanks for pointing this out again. II just have realized an example where this indeed could be very useful. So we have added a new parameter to the linear regression learner called "use_bias" which can be turned off. You can obtain the new version via CVS (described here: http://rapid-i.com/content/view/25/48/
; please use the branch "Zaniah" for the latest developer version). Of course, this new feature will also be part of the next Enterprise Edition update.
